The use of innovative technologies in the field of design has significantly expanded the range of interior solutions for the kitchen, where the equipment used must be not only aesthetic, but also functional. In accordance with existing requirements, modern kitchen should be equipped with a number of devices and accessories designed to optimize the cooking process. One of these devices is a kitchen sink, the installation of which only at first glance seems like a fairly simple task. However, given the variety of models and possible places its placement, it is important to approach the choice of design and the procedure for its placement most responsibly. Despite the wide model range, the most popular are mortise structures made of stainless steel and built into the kitchen countertop. Given the popularity of these products, it would be most appropriate to consider design features this product and searching for an answer to the question: “How to install a built-in sink into a countertop?”

Principles of ergonomics in the kitchen: the role of the kitchen sink

To optimize the cooking process, it is necessary to properly arrange kitchen furniture and appliances. Surely everyone is familiar with the concept of “ergonomics” and its basic principles, which may vary somewhat depending on the type of room. The kitchen is no exception - renovations in this area are subject to strictly defined ergonomic principles. In accordance with them, the arrangement of furniture and equipment in the kitchen depends on the order of work, and therefore, it is recommended to arrange furniture from left to right in a strictly defined sequence: refrigerator - dishwasher(if available) - sink - stove. It is recommended to place work surfaces with cabinets between the mentioned technical objects.

As for the minimum distances between objects, they are also subject to certain requirements:

• The distance between the sink and the stove, as well as between the refrigerator and the sink should be 40 cm;
• The refrigerator and stove should also be located at a distance of 40 cm from each other.

What should you consider when choosing a kitchen sink?

When choosing a kitchen sink, pay attention to the following factors:

• Functionality, determined by the nature of the work being done in the kitchen and depending on the number of additional bowls in the sink and drying wings. These compartments will be useful if you are used to carrying out several manipulations at once in the kitchen;
• Capacity, in the process of determining which it is necessary to pay attention to the number of dishes washed daily;
• Stability and durability, largely dependent on the material from which the structure is made;
• The design solution and design of the sink should be such that it fits perfectly into the surrounding environment and becomes a full-fledged element of a holistic interior concept;
• Ease of use: the configuration of the sink should be such that it is comfortable to stand and work near it.

Design types of kitchen sinks: brief description

There are a number of requirements for installing a kitchen sink, and therefore it must be carried out in accordance with a certain technology. The choice of the required technological solution, and, accordingly, the installation method depends on the design of the sink. Let's look at the most popular design types:

• Overhead sinks- most budget option, distinctive feature which is the ease of installation of the structure. The principle of their installation is based on the fact that the sink is placed on a separate cabinet, and therefore they become a continuation of the countertop, as if replacing it. Despite the undeniable advantage described above, sinks of this type also have disadvantages - the relatively small thickness of the product and the formation of a gap between the sink and the countertop, which leads to additional inconvenience;

Important! Experts recommend giving preference to overhead models if the kitchen set consists of separate sections. If kitchen modules are combined under a common countertop, it would be more appropriate to use built-in models.

• Built-in sinks- are models that are installed directly into the countertop, and therefore installation activities must begin with the preparation of the appropriate hole in the countertop. The technology for installing mortise sinks involves attaching the structure to the inside of the countertop using special clamps and brackets. Built-in sinks of this type are characterized by a solid appearance and ease of use. Despite the fact that the cost of such models is somewhat higher, experienced specialists often prefer them due to their practicality and the ability to avoid moisture accumulation between the cabinets;

• Underbench sinks- innovative models, the high cost of which reduces their widespread availability and limits their widespread use. The principle of installation of these plumbing products involves their fastening below the level of the countertop, and therefore they form a single whole with it. The advantages of undermount sinks are aesthetic appearance, high noise absorption and effective sealing of joints. In addition, such products are hygienic and durable.

Materials for the manufacture of mortise and overhead sinks

As for overhead and mortise sinks, both are made of stainless steel with the same frequency, remaining on at the moment one of the most popular. The appearance of mortise stainless steel sinks can be different - the most common are smooth sinks and sinks with a texture that imitates linen.

In addition to traditional sinks made of stainless and enameled steel, mortise sinks made of stone and mineral-epoxy are no less popular. composite materials. Artificial stone is also a popular material. Sinks made from composite materials have an impressive grain structure that resembles polished stone in appearance. Built-in sinks from artificial stone constitute a wide group of kitchen accessories characterized by high aesthetic and performance characteristics, including resistance to scratches, abrasion and sudden temperature changes.

The shape of sinks is no less varied - along with single-bowl sinks, there are also models with several (from two to four) bowls, which can be either shallow or deep, equipped with additional dryers.

Installation Basics for an Overmount Sink

• Installation of an overhead sink is carried out on a separate module kitchen countertop so that it completely covers its upper part. This installation is quite simple - the equipment is fastened using L-shaped elements with an oblique slot. To fasten one sink, you need to prepare at least 4-5 fasteners.

Important! Before you begin installing the sink, you need to connect the faucet, which will subsequently avoid difficulties during the installation process.

• Attach the fasteners prepared in advance to the inside of the cabinet and leave the appropriate marks;
• Prepare the shortest self-tapping screws (15 mm) and screw them in the marked places so that at least 5 mm protrudes above the mark;
• Treat the end of the cabinet with sealant, which will protect the furniture and increase the reliability of the sink;
• Install the sink on the screwed-in screws and move until it fits completely;
• Fix the fasteners and, after removing excess sealant, connect the sink to the water supply and sewerage systems.

Installing an undermount sink into a countertop: a step-by-step guide

Let's consider the principle of installing a mortise sink in a countertop made of chipboard, covered with plastic on top. If you are wondering how to attach a mortise sink to a countertop made of other materials, including artificial stone, carefully read the product data sheet, where the manufacturer must describe in detail recommendations for working with this material.

Preparation of materials and tools

Before you begin installing the sink, check that it is complete with mounting materials. Most often, these are special clips that are mounted on both sides - on the cut end of the countertop and on the inner surface of the sink. In addition, the kit should include a tubular sealant, which will be required to seal the joints. In addition, prepare the following set of tools:

• A jigsaw that can be replaced with a regular one hand tools, and a set of spare wood saws;
• Drill with a 10 mm drill (for metal) and self-tapping screws;
• Standard set of measuring tools: construction knife, level, corner, tape measure, Phillips screwdriver, ruler and pencil;
• Colorless silicone sealant necessary for sealing cracks and joints.

Performing markup: important nuances

• Markings made in accordance with the recommendations below will be relevant when installing a standard mount sink rectangular shape. When installing a round mortise sink, familiarize yourself with the additional installation nuances.
• Using a pencil, in the place where you plan to install the sink, draw two perpendicular lines, at the intersection of which the drain will be located;
• Turn the sink over and place it on the countertop with the bowl facing up and align it in accordance with the prepared markings (you can see the intersection of the axes through the drain hole). Take a simple pencil and trace the outer boundaries of the sink around the perimeter. In this case, it is important to take into account the dimensions of the mortise sinks, as well as the relative position of the boundaries of the sink and the remaining free edge of the countertop, the presence of which is necessary for the rational installation of cabinet doors;

Important! To prevent a sink embedded in the countertop from becoming an obstacle to closing the cabinet doors, it must be located inside the cabinet.

• Next, measure the width of the side of the sink and, in accordance with the obtained value, draw an internal contour along which the cutting line will run. Despite the fact that the width of the side is an individual value for each sink, on average it fluctuates within 12 mm.

Important! The size of the hole must be such that the sink fits freely into it, while the permissible deviation from the markings should not exceed 3 mm.

How to properly cut a hole in a tabletop?

• This process is carried out using a jigsaw, however, before the saw of the tool enters the full depth of the material from which the tabletop is made, it is necessary to make technological holes to facilitate the work process. Holes are made using a drill or screwdriver in the corners of the internal markings.

Important! The corner holes should be located in the inner plane of the cutting area, and their edges should only be in contact with the cutting line.

• To avoid chipping the laminated surface, the entire cutting area must be performed on the front side of the tabletop.
• After you have made holes in the corners of the cutting plane, use a jigsaw to cut a hole along the inside cutting line. To prevent the cut part of the tabletop from falling, screw in self-tapping screws along the cut line, which will ensure its fixation.
• After you have made a hole in the tabletop, remove the screws and the cutting part of the tabletop from the main plane, clean the cut from dust. Pre-install the sink into the resulting hole, which is necessary in order to check the product’s compliance with the dimensions of the hole.

Important! The sink should fit freely into the resulting hole (if difficulties arise, you need to trim the edges with a jigsaw).

• During the preparation of the hole, all kinds of microchips and roughness can form on the internal cut line. In this regard, it is necessary to consider the rules for processing a slice; if neglected, the following problems may arise:
• Absolute sealing of untreated chipboard surfaces practically impossible;

Important! Insufficient sealing will lead to moisture entering the unprotected area of ​​the countertop, which will cause the activation of rotting processes and the formation of fungal plaque. Subsequently, the cut edge will become brittle, which will reduce the stability of the sink and lead to its distortion.

• Rotting of the countertop will soon lead to a decrease in its physical, aesthetic and operational characteristics, and therefore there will be a need to replace it.
• To avoid this, the end side of the cut is sanded with fine-grained sandpaper;
• Carefully treat the entire cut area with plumbing sealant. Experts recommend doing this work with a spatula; if you don’t have one, you can do it with your finger. By taking such protective measures, you will prevent the tabletop from getting wet and swelling.

Important! If during the work you find chips on the plastic (the front side of the tabletop), carefully coat them with sealant, and it is not at all necessary that the layer be thick - its thickness in this case does not matter.

• There is another way to protect the end side of the cut - treatment with PVA glue. Despite the fact that it is more labor-intensive - in terms of its reliability it is not inferior to the previous one, however, for greater protection, the applied layer of glue must dry for 30-50 minutes.
• The next stage involves gluing a seal made of foamed polyethylene (it was previously noted that it should be included with the sink). It is glued to the side of the sink along its entire perimeter. If, after gluing the sealant, you find protruding edges of the material, carefully trim them with a knife. If you neglect this advice, you will find that the edges of the sink do not fit tightly to the countertop, and water entering the gaps will lead to swelling and subsequent rotting of the ends of the countertop.

Due to the fact that the process of gluing the seal directly determines the wear resistance and performance characteristics future headset, let's look at it in more detail.

• Take the seal and, using a rag moistened with gasoline and solvent, degrease it;
• Apply sealant to the seal using a continuous strip (the sealant strip should be thin enough so that the glue does not come out during compression);
• Press the seal against the outer edge of the sink.

How to attach a built-in sink to a countertop?

• Apply a layer of silicone to the countertop (between the cut and the outer marking line);
• Install the fasteners on the inside of the sides of the sink and, making sure that they are not fully secured, proceed to install the sink. It begins with a recess on the side where the faucet will be attached;

• Subsequently, the rest gradually fits into the hole until the sides of the sink come into close contact with the inner surface of the countertop.

Important! When installing the sink, press firmly on the entire surface of the structure, which will allow you to remove excess silicone from under the sides of the sink.

• Using building level, make sure that the installation is correct, and then proceed to the final stage - the final fastening of the fixing elements;
• Having completed the activities described above, proceed to connecting communications. For this purpose, hot and cold water connect to plumbing system using a sealing gasket.

After securing the hoses, installation activities look like this:

• Insert a siphon outlet into the sink (it is recommended to give preference to the S-shaped design);
• Add a hard corner or soft corrugated pipe to the siphon;
• Lead the pipe from the siphon into the sewer pipe;
• Check all system connections for leaks.

How to cut a hole in a countertop if it is made of artificial stone?

• In most cases, countertops made of artificial stone are ordered with holes designed for a specific sink, however, if such conditions were not agreed upon in advance during the ordering process, you can contact specialists who, using special tools, will cut a hole of the required shape and size.
• If you want to carry out the work yourself, in accordance with the technology described above, use an angle saw instead of a jigsaw grinder(grinder), as well as a disc for cutting concrete with diamond coating.

Features of installing corner, round, and granite sinks

The process of inserting a corner and round sink is identical to that described above, however, for both types there are certain installation features.

Features of installing a round sink:

• Experts recommend making several holes along the cutting line in increments of 7-10 cm, which will facilitate this process;
• If the sink model you choose does not come with a template for the cutout, make one yourself.

Features of installing a corner sink:

• Due to the fact that the angle of rotation of the cutting lines is less than 90 degrees, in order to improve the passage of the jigsaw saw, make several holes along the cutting line - in corner connection lines and at a distance of 2-3 mm from it.

Specifics of installing a granite sink:

• The point is that the design of a granite sink does not imply the presence of holes for installing the drain siphon of a mortise sink and tap. You need to do them yourself using a drill equipped with a special attachment. If you have no experience working with artificial stone equipment, you need to be extremely careful, since the slightest mistake can cause the equipment to become defective.

1 Ergonomics in the kitchen

Food preparation must occur accurately and quickly. This is primarily influenced by the location kitchen furniture and technology. In accordance with the principles of ergonomics, kitchen equipment must be placed depending on the order of work, that is, from left to right: refrigerator, dishwasher, sink, stove, and between them work surfaces with cabinets.

The minimum distance between individual devices should be:

• 40 cm between the refrigerator and the sink, as well as between the sink and the stove,
• 40 cm between the refrigerator and the stove.

For right-handed people, the most convenient way is to place separate workspaces from right to left. Regarding the sink, this means that the sink should be on the right and the drain on the left.

It is best if the sink is installed near the connection to the water supply and sewerage system.

The drainage system at the sink is made of pipes and siphons with a diameter of 40 and 50 mm.

2 Types of sinks

When choosing a kitchen sink, you should pay attention to the following factors:

• Capacity. It is determined by the number and size of dishes washed daily.
• Functionality. It is determined by the nature of the work carried out in the kitchen, the number of additional bowls in the sink and wings for drying. If you have to carry out several personal manipulations in the sink at the same time, then these compartments will be very useful.
• Ease of use. You must be comfortable standing and working at the sink.
• Stability and durability. These parameters are determined by the material from which the sink is made.
• Combination with kitchen interior. The sink must match the style, design, color scheme and, of course, the size of the entire kitchen.

From an installation point of view, there are two main types of sinks:

• applied to a kitchen cabinet (overhead),
• built into the kitchen countertop (mortise).

When installing built-in sinks, it is necessary to accurately cut a hole in the countertop for the selected sink. In the case of slabs made of chips, this is not a big problem, but if the tabletop is made of stone, conglomerate or composite, then special cutting tools are necessary. 

MATERIALS USED FOR THE PRODUCTION OF WASHES

Surface-mounted sinks are made of stainless or enameled steel. The two most common options for the appearance of steel sinks are smooth and linen-textured.

Drop-in sinks are made from stainless steel, mineral-epoxy composites and solid artificial materials.

Composite sinks often have an impressive grain structure, reminiscent of polished stone. Sinks made of artificial materials can be completely one-color. This group of kitchen accessories is characterized by an impressive appearance and high resistance to abrasion, scratches, dents and high temperatures.

WASH FORMS

Steel sinks have the widest range of shapes and varieties. In addition to the usual single-bowl sinks, there are sinks with several bowls (usually 2-4), which can be either shallow or deep, with additional side drains.

3 Installation of an overhead sink

The surface-mounted sink is designed for installation on standard cabinets standard width 50, 60, 80 cm. For installation you need: tape measure, screwdriver, 4 wood screws, clamps for overhead sink 4 pcs, sanitary silicone. Installation is carried out after installing the cabinet in the chosen place in the kitchen. We determine how far the sink should hang over the front wall of the cabinet. We subtract the second size from the first and get the distance where the screws should be screwed in. We screw the screws into the upper part of the cabinet walls - do not screw them all the way, the heads should stick out a little so that they can snap into the holes in the base of the sink. We insert the sink - the heads of the screws should fit into the round fragments of the holes. Push the sink towards the wall so that the screws are locked at the end of the base. Check to see if the sink is inserted tightly; if it moves, remove it and tighten the screws. We insert it into the cabinet again. This installation method ensures a stable installation of the sink. If there is a metal splashback on the back of the sink, it should fit snugly against the wall.

4 Installation of a mortise sink

Built-in sinks are designed for installation in kitchen countertops.

The first step is to cut a corresponding hole in the tabletop. In wood and laminated worktops particle boards We cut out the hole using a jigsaw for wood.

For countertops made of stone, conglomerates or composites, special devices are used when cutting holes, so this service must be ordered when purchasing them. It is necessary to indicate the dimensions of the hole and the exact location of installation of the sink. The size of the hole for the sink is obtained by measuring the length and width of the apron on the bottom of the sink.

ATTENTION

The hole should be 0.5 cm wider and longer than the apron.

1. The apron serves for stable installation of the sink. Some sinks come with a sample hole for the sink, which you just need to outline on the countertop.

2. Use a jigsaw to cut a hole in the tabletop.

3. We insert the seal under the sink, which is included with the sink.

ATTENTION

Wooden and laminated countertops must be protected from moisture after cutting the hole. Cover the edges of the cut hole generously with sanitary silicone. After it dries, you can begin installing the sink.

Steel sinks are fixed in the hole using clamps. Upper part fasteners are attached to holes drilled in the sink apron. Bottom part rests on the bottom of the tabletop. Both parts are connected with a screw. By tightening the screw, we clamp the fastener and fix the sink in the hole.

4. After centering the sink in the hole, screw the first fastener. We don’t twist it all the way, leaving it a little loose.

5. In the same way, screw on the fastening located opposite.

6. Carefully tighten all the fasteners one by one.

7. The last stage of installation is to tighten all the screws one by one so that the entire contour of the sink rests on the countertop.

8. We install the mounting points of the latches in the hole cut out in the countertop in accordance with the drawing attached to the product by the sink manufacturer.

9. Screw the clamps into the designated places. There can be from 6 to 12 pieces. 

10. We glue self-adhesive sealing tape along the edges of the sink, which, depending on the manufacturer, is included in the kit or sold separately.

11. Fix the sink by carefully inserting it into the hole in the countertop. First, the tabletop will rest against the edge of the apron on the latch tongues.

12. We apply pressure to the sink at the places where the latches are installed. The tabs will snap into the recesses made on the sink apron. After fixing is completed, you can begin installing the mixer and siphon for draining.

ATTENTION

The precise placement of the latches and the precisely cut hole ensure that the sink is properly secured.

Having purchased kitchen furniture and plumbing fixtures, many turn to professionals for help. But it often happens that there is no one to expect help from and you have to do everything yourself.

You need to learn in advance how to install an overhead sink on a cabinet in the kitchen in order to be prepared for possible difficulties and nuances.

So, we purchased convenient plumbing fixtures that fully meet the owners’ needs in practicality and appearance. By the way, stainless steel sinks are popular for kitchens today. Firstly, they are affordable, light weight, and durable to use.

The universal metallic color can be combined with a variety of color solutions indoors.

Installation is quite simple, there are only two stages:

1. Assembling the sink cabinet;
2. Installation of an overhead stainless steel sink on a cabinet.

Washing – indispensable attribute kitchens. You can easily install it yourself - you do not need to have special knowledge and skills.

Furniture assembly

The first stage requires preparing the furniture itself so that the plumbing can be installed. Usually delivered to the customer in disassembled form. If you don’t know how to assemble a sink cabinet, the instructions included with the furniture will help.

Looks like a diagram.

The standard set is:

• 2 side walls;
• 2 doors (or one);
• Bottom;
• 3 frames for rigidity;
• Fittings, corners, screws.

You need to have a screwdriver on hand to carry out assembly, or a standard furniture hexagon.

Installing a sink: what is needed for this?

How to attach a stainless steel sink to a cabinet so that it holds well and the installation itself does not take too long? To do this, you need to have accessories and tools, thanks to which installing the sink on the cabinet will not be much of a problem.

Attach the sink to sealant without additional accessories It's possible if it's light. If the overhead sink is heavy, then installing it on the sealant will lead to the collapse of the structure. In this case, it must be fastened with self-tapping screws.

The classic tools and accessories used for such purposes are:

• Drill, screwdriver;
• Screwdrivers;
• Ruler;
• Pliers;
• Drills (for wood);
• Self-tapping screws;
• Sealant (we’ll give it special attention further);
• Masking tape;
• L-shaped corner.

The above items are also suitable for installing a sink on a countertop.

But experienced craftsmen All you need is a sealant and corners.

Installation

We lay out the tools and accessories in advance so that they are at hand. It is also advisable to decide on the mixer and siphon so that everything is installed at once, otherwise it will be difficult to install later.How to attach a stainless steel sink to a cabinet? This is not difficult if you have already completed the assembly of the frame itself.

1. L-shaped fasteners are installed, either included in the kit or purchased separately.
   

   

   For fastenings, it is better to purchase L-shaped plates with oblique slots at a fastening store. You will need 4-5 plates.

2. Attach with inside fasteners and mark under them the places where it is necessary to screw in the self-tapping screw. Drill a hole (not through) 0.5 cm above the mark, screw in a self-tapping screw and install the fastener. Do the same actions in other places of the structure.
   

   

   During the assembly process, make sure that all holes are at the same level.

3. Next, assemble the plumbing product, attach the siphon with all the gaskets to it, and attach the mixer.
   

   

   Before installing the overhead sink itself on the base or cabinet and securing it, you need to assemble it completely - secure the siphon and mixer in their places, install gaskets.

4. Treat the ends of the walls with sealant. It is needed so as not to protect the furniture from moisture.
   

   

   This product provides additional fastening of the sink to the cabinet in the kitchen.

5. Now you can start fixing- put on furniture frame, where the fastenings are placed on self-tapping screws.
   

   

   The fasteners are placed on self-tapping screws and moved along the slot. This presses the sink against the cabinet.

6. Do it plumbing work for connecting water supply and drainage in the kitchen.
   

   

   Take care of the accuracy of the work and reliability.

7. After attaching the stainless steel sink to the cabinet is completed, you can check it for leaks. The sink fills with water. Check if water is seeping out at the junction of the sink and siphon.
   

   

   If water leaks out, the system is assembled incorrectly.

8. Installing kitchen cabinet doors- the final stage, which will become the final point in plumbing work.
   

The sink is secured to the cabinet with fasteners and a sealant. This is the most reliable way, quite durable.

So the question of how to install a stainless steel sink on a cabinet has been resolved. If the work is done correctly, it can stand for a long time.

Many people attach the sink to the countertop. There are options when, when ordering kitchen furniture, the need for a hole in the countertop for installing plumbing is specified. Then there will be little work involved in installing the sink.

If there is no specially allocated space on the countertop, then you will have to do everything yourself.

1. Mark the contours on the surface with a pencil. Take into account the margins from the edges (5 cm). Take measurements for the bowl.
   

   

   Remember that the gap from the edge of the countertop to the side of the sink must exceed 50 mm. If this distance is less than 50 cm, then the sink needs to be deepened.

2. Make a hole in the corners of the outline.
   

   

   To make a hole in the tabletop you will need an electric jigsaw.

3. From the contour with outside glue masking tape so that the surrounding surface is not damaged during operation. Before cutting the opening, secure the part to be removed from below so that if it falls, it does not damage the surface underneath.
   

   

   To avoid chipping on the front surface, choose the opposite direction of the tooth.

4. Treat the ends of the countertop with sealant, assemble all the plumbing elements (mixer and siphon) and install. This will prevent moisture from getting under the structure, thereby spoiling the appearance of the furniture by deformation and delamination.
   

   

   Stepping back a couple of millimeters from the edge of the hole, we apply silicone with a bead of thickness just above the side of the sink.

5. Secure with clamps (included with purchase).
   

   

   The sink needs to be inserted into the hole and the edges should be pressed firmly so that the silicone strands take the shape of the sink and left for a few minutes.

So, having looked at how to attach a stainless steel sink to a cabinet with fasteners and to a countertop, you will notice that doing this is not as difficult as it seems.

The most difficult thing is to make the hole correctly. If it turns out to be larger than expected, the paws will not be able to hold the sink.

Selecting a sealant

Big role in installation work plays a sealing role. The following types of products are available on the market:

• Silicone acrylic;
• Elastic silicone;
• Polyurethane silicone.

When purchasing, you need to pay attention to the features and characteristics of the sealant: shrinkage, adhesion, purpose.

Apply the product to a dry, clean surface to ensure maximum adhesion. If the surfaces are not fully prepared for sealing, then moisture may penetrate into the cracks, which can lead to the growth of fungus and mold.

Typically, elastic silicone sealing material is used. It is easy to use and quite reliable.

Summing up

Advantages of installing a sink yourself:

• There are tools in almost every home; attaching an overhead sink to a cabinet can be done using almost improvised means;
• You can save on the cost of a professional plumber by doing the steps yourself;
• If the plumbing product did not come with any fasteners, then purchasing them is not a problem.

If you cannot install the plumbing yourself, it would be better to turn to professionals.

VIDEO: Installing a stainless steel kitchen sink.

Based on the principle of placement on the underframe, sinks are divided into overhead and built-in. The surface of the washing panel can be located above the plane of the countertop, be flush with it, or be below the level of the desktop. In any case, the bowl under the mixer should be installed between the sections of the headset to accommodate dirty dishes and for cooking and serving dishes.

The cabinet on which the overhead sink is mounted is often separate element kitchen interior. Mortise and integrated sinks are mounted into the continuous surface of the desktop of the floor-standing modules of the sets.

Installation of an overhead washing panel

Sink connection diagram: 1 – mixer pipe; 2 – gasket; 3 – fixing nut; 4 – flexible hose; 5 – pipeline supply; 6 – overflow hole; 7 – combined drain; 8 – drain device; 9 – compression ring; 10 – compression coupling; 11 – double-turn siphon; 12 – drain pipe.

Overhead types of sinks are easier to install than others. This traditional way installation of dishwashing equipment. In the kitchen interior, it is a free-standing cabinet with a sink, complemented by a panel for storing washed kitchen items.

The panel is fixed on the cabinet using fasteners in the form of brackets or pushed onto the base into the grooves of the cabinet using special slides.

The sink kit may include an adhesive tubular seal that is inserted into a groove on the panel. The joint between the cabinet and the washing panel is coated silicone sealant to protect against moisture penetration.

Rubber seals do not adhere tightly to the joining surfaces and have a short service life. More often they are replaced with a moisture-resistant sealant; it tightly fills the gaps and retains its properties for a long time when dry.

The underframe usually does not have additional internal elements; this provides access for repairing supply pipelines, cleaning the siphon and sewer pipes. Sometimes supporting bars are attached under the overhead sink to enhance the strength of the structure.

Before attaching the sink to the countertop, the faucet, water supply hoses and siphon are installed. The overhead sink is secured with L-shaped fasteners with an oblique slot. 4-5 such elements are installed. In marked on inner surface Self-tapping screws are screwed into the cabinets and places for fastening. They should protrude 5 mm from the walls of the underframe. It is better to screw in the screws with a screwdriver; if you use a screwdriver, the tabletop may be damaged.

During installation, the fastening grooves are placed on the screws and the sink is moved until it is firmly fixed to the overhead sink. Then the screws are tightened and the protruding sealant is removed.

Installation of a mortise sink

To prevent water from splashing when washing dishes, choose a deep sink and install a low tap.

The sink is installed in a pre-cut hole in a solid countertop. In this case, the sink itself can be made of various materials: stainless alloy, earthenware, porcelain, etc.

To insert a washing container, you will need some tools and additional materials:

• jigsaw with a fine-toothed file;
• drill, screwdriver;
• pencil, ruler, tape measure;
• self-tapping screws, silicone sealant;
• wrenches for installing the mixer;
• sandpaper, construction knife.

The contours of the installed panel are marked with a pencil, turning it over and laying it on the countertop. The distances from the front and rear edges of the latter are at least 5 cm. Then the location of the bowl relative to the edges of the panel is measured. The outline of the hole cut for the sink appears along them.

The bowl can be of various shapes, so it is necessary to transfer its geometric parameters to the surface of the tabletop as accurately as possible. Manufacturers of mortise sinks often include a template with the kit, according to which the shape of the hole is drawn.

The cutting line should extend outward from the sides of the bowl by about 1 cm. A hole is drilled at one of the points on the contour to insert a jigsaw blade. For a rectangular bowl shape, holes are drilled in the corners of the intended contour.

Painting tape is glued to the outside of the outline. It will protect the surface of the tabletop from damage by the jigsaw foot when cutting. On a removable tabletop, the material is cut with a jigsaw with front side, this way the surface cladding is less damaged. In the process of cutting the opening, self-tapping screws are screwed into the cut to a small depth so that the inner part does not fall out during operation. The sector to be removed can also be secured from below with support.

The edges of the table top along the saw cut are covered with silicone sealant to protect the material from moisture penetration. The sealant is also applied under the edges of the panel along the drawn contour. The sink with built-in faucet and siphon is inserted into the prepared opening and secured to the countertop with clamps included in the kit. plumbing fixture. All that remains is to connect the mixer to the water supply and drain the sink through a siphon to the sewer.

Today there is a wide variety of all kinds of mortise (built into the countertop) kitchen sinks made of different materials having various shapes and colors. The most popular, inexpensive and at the same time durable type of kitchen sink can be considered stainless steel sinks. Let's look at how to install a stainless steel kitchen sink with your own hands, using simple household power tools. Absolutely any mortise sinks are installed using the same principle.

We will install the sink in a countertop made of chipboard, covered with plastic on top - the most common type of kitchen countertop. If necessary, e When installing a sink into a countertop made of another material (for example, artificial stone), you must follow the recommendations of the countertop manufacturer. There are also overhead sinks that are simply put on (placed) on top of the cabinet; such sinks are considered obsolete and are used extremely rarely; they will not be discussed in this article.

To install a kitchen sink, we need:

1. Pencil, tape measure, ruler, construction angle, Phillips screwdriver, sharp knife.
2. Jigsaw with file type Bosch T101B orT101BR.
3. Electric drill with a metal drill with a diameter of 10-12 mm.
4. Several self-tapping screws 16-30 mm long.
5. Silicone colorless sealant (universal or plumbing).

Marking.

Accurate marking is the key to successful installation. To begin with, you need to decide on the axis of symmetry, that is, symmetrically to what the sink will be installed. Usually, the line of the center of the sink bowl (for a round one - its diameter) goes along the center of the cabinet above which the sink is installed. Other installation options are possible, depending on the specific case (configuration kitchen set). As a rule, the distance from the front edge of the tabletop should not be less than 50 mm, and from the rear edge - less than 25 mm. However, these figures cannot be considered universal, and depending on the size of the sink, as well as the features of the insert, the figures may be different. With a pencil we draw two perpendicular axes on the front surface of the tabletop, indicating the center of the bowl and mark the boundaries of the sink (left, right, top, bottom).

Indentations from the edges of the tabletop.

Place the sink on the front surface of the countertop with the bowl facing up and align the sink relative to the markings made. Carefully, without moving the sink from its place, outline the outer contour of the sink with a pencil. We remove the sink from the countertop.

Depending on the manufacturer, the stainless sink kit (d Most sinks made of artificial stone do not have such fastenings.) may include metal, or plastic fastenings. If possible, preference should be given to metal (all-metal) fasteners, as they are more reliable. Before installing the fasteners on the sink, it is recommended to disassemble them (by separating the parts mounted on the sink and on the countertop from each other). By clicking, the parts of the fastenings are installed on the sink into the corresponding metal eyes so that the fastenings protrude minimally outward - “looking” into the inside of the sink.

Part of the fastening installed on the sink.

We accurately measure the width of the sink side (the distance from the outer edge of the sink to installed fasteners), taking into account the protrusions of the fasteners. As a rule, the width of the rim of a stainless steel sink ranges from 10 to 15 mm.

The sink is ready to be outlined on the countertop.

Parallel to the outer contour of the sink previously drawn on the countertop, draw by hand (or using a ruler to control accuracy) another contour - the cutting line - inside (closer to the center of the sink), indented by the width of the side of the sink minus 1-2 mm. The sink should fit freely into the future hole, allowing up to 2 mm of play on each side.

Marking the cutting line.

Cutting a mounting hole in the countertop.

In one (for a round sink) or several places (in the corners of the markings, for a rectangular sink) of the countertop, we make a through hole with a 10-12 mm drill so that the future hole is close to the cutting line, but does not touch it (it is closer to the center of the sink) . It is necessary to drill from the front surface of the tabletop! We get a hole(s) for the file to enter.

Using a jigsaw, exactly along the cutting line, we make a closed cut. To keep the inside of the tabletop in place (not fall down), you need to screw screws into the gap from time to time, which will act as temporary fasteners (wedges). We insert the sink into the countertop, check that the cutout is made correctly (the sink should fit freely with a slight play), if necessary, perform additional trimming with a jigsaw.

Close-up of the hole.

Small chips of plastic are acceptable.
To avoid chipping at all, you need to use a fileT101BRwith reverse direction of teeth.

After sawing is completed and the unnecessary (inner) part of the tabletop is removed, it is necessary to clean the cut from dust and carefully cover it with silicone sealant (using a small rubber spatula), this will prevent the tabletop from swelling when water gets in. You also need to lubricate the plastic chips that formed during sawing. There is no need to get too carried away - there is no point in covering the cut with a thick layer of sealant.

Applying sealant to the cut.

We glue the foamed polyethylene seal (included with the sink) to the side of the sink around the entire perimeter. If, after gluing the seal, it protrudes beyond the outer contour of the side (rises above it) by more than 1 mm, then the seal must be trimmed with the sharp tip of a knife, otherwise there is a possibility that the fasteners will not be able to fully press the seal and press the sink to the plane of the countertop . If we are dealing with a sink made of artificial stone, then there is no need to glue any seals.

Using a clean cloth soaked in gasoline or acetone, degrease the surface of the seal and the line of contact of the seal to the countertop. We apply the sealant to the sealant in a continuous strip, not being carried away by the thickness of this strip (it is assumed that the sealant is glued flush with the protrusion of the side). In practice, you can find a way to install a stainless steel sink without using a sealant at all; in this case, the entire space designed for inserting the sealant is filled with sealant. This is acceptable, but undesirable for several reasons: high consumption of sealant (as a result, long drying time), difficult control of filling the seam, and the labor-intensive process of dismantling the sink in case of unsuccessful installation. An exception is the installation of a sink made of artificial stone; such a sink is mounted only on sealant.

Applying sealant to the seal.

Sink fastening.

We insert the sink into the hole in the countertop and align it with the markings (the markings must be applied so that they are partially preserved after cutting out the countertop). We take two or four fasteners and, equidistant from each other, pre-fasten the sink (without fully tightening the fastenings), constantly monitoring its position relative to the markings. Attention! Tightening the sink fasteners must be done manually, without using a screwdriver, as the threads in plastic parts are easily torn off! We turn the tabletop upside down (for convenience), install all the fasteners, and finally tighten them, trying to do this evenly and consistently. So that the sharp spikes of the fastenings in the best possible way stuck into the countertop, you can sharpen them with a file and/or lightly tap them with a hammer while tightening them.

Mounting on the sink assembled form. By tightening the self-tapping screw, the sink is attracted to the countertop. The sharp ends of the metal part of the fastening must be securely fixed in the tabletop.

Tighten the fasteners with a screwdriver.

The fastening is tight. It is recommended to lightly tap the fastener with a hammer to sharp ends cut deeper into the tabletop.

All fastenings are tight.

Let's look at the result of the work: the sink should be pressed along the entire perimeter to the surface of the countertop, installed along the marking lines. Indirect confirmation of the complete fit of the sink can be the squeezed out sealant. Use a cloth to wipe off excess sealant and markings from the front surface of the countertop. Allow the sealant to harden overnight. If the sink is made of artificial stone and is not equipped with fasteners, it is necessary to ensure that it is completely immobile while the sealant is curing.

The sink is well pressed to the countertop. The sealant squeezed out slightly.

Installing a built-in kitchen sink is a responsible undertaking. Poor installation of the sink can not only spoil the appearance of the kitchen, but also lead to rapid failure of the countertop due to water penetrating under the sink onto the cut of the countertop. Primary importance should be given to sealing the sink-countertop joint; do not rely on well-executed processing of the cutout end.
