How to install a sink in the kitchen: installation rules for mortise and free-standing models. Installing a sink in the kitchen - do-it-yourself, reliable and durable

Overhead sinks are the most popular design of kitchen sinks. Affordability and ease of installation form a high demand for overhead construction in the market kitchen furniture.

Overhead kitchen sinks got their name due to the installation method. The sink is superimposed on the kitchen cabinet from above and closes it instead of the countertop.

The overhead sink is table top with bowl made of stainless steel.

The operation of the overhead sink is impossible without the kitchen cabinet on which it is installed. Therefore, the sink and the supporting cabinet represent a single structure in the kitchen interior.

All overhead sinks on three sides (on the sides and in front) are equipped with sides for mounting on the pedestal. The rear side of the overlay structure adjacent to the wall does not have a side, but there is a raised edge to prevent water from draining to the floor (between the wall and the sink).

The shape of the sink in the overhead sink is most often rectangular with rounded edges. Smoothing right angles makes cleaning easier inner surface shells. It is possible that the sink will be provided with two bowls - main and additional.

In addition to the sink, the design may include a countertop, monolithically connected to the bowl. It is designed for storing wet dishes, as well as for laying out fruits and vegetables after washing. The surface of the metal countertop is made in the form of small protrusions and depressions so that dishes or food do not roll back into the sink. It can be located both to the right and to the left of the bowl.

An emergency drain can be provided in the back wall of the sink recess (in case the bowl overflows with water). When installing, the side hole is connected to the main drain. Often the bowl is supplied with a grate for sifting out large food residues, installed in drainer. Such a piece provides two functions: it prevents clogging of the drain pipe with leftover food and can close the sink hole as a plug.

Cabinet under the sink represents a special furniture design, in which there is no back wall(for connecting the siphon with drain pipe) and no shelves. Often the cabinet space is used to store auxiliary tools: a trash can, a floor bucket with a rag, empty cans, old pots. The front is closed with doors, its outer surface can look like any desired material: light or dark wood, marble.

Advantages and disadvantages of the overhead sink design

describe dignity countertop stainless steel sink can combination of four main features: it works for a long time, it is easy to install, it looks normal and it is inexpensive.

Availability in price. These are the cheapest sinks on the market.
Ease of installation. The assembly of the sink consists in laying it on top of the cabinet and fixing the assembled structure with self-tapping screws.
Sufficient service life. The overlays are resistant to water corrosion, so the sink lasts for many years without the need for painting or derusting.
Aesthetic look. The shiny surface of the metal is easily cleaned of grease, while it does not require special expensive cleaning products (such as marble).

disadvantages overhead structures are manifested in the case of cost savings and the purchase of a sink with thin walls(up to 1 mm). These sinks:

prone to dents;
do not hold the mixer well;
make a lot of noise when the water jet falls.

In general, increased noise production is typical for all metal sinks, regardless of the type of construction (consignment note or mortise). It can be significantly reduced by purchasing a sink with a normal metal thickness (1 mm).

Sometimes overhead structures are subject to claims of lack of diversity and design decoration shells. Indeed, overhead sinks are standard and are available in several of the most popular sizes. However, such an accusation is not relevant and is not a disadvantage. The fact is that this type of kitchen equipment (due to affordability) does not pretend to be a designer expensive kitchen arrangement.

Overhead sink dimensions

The dimensions of the overlapping sinks are standardized to the dimensions of the perimeter of the produced kitchen cabinets. The most common size of an overhead sink is 50x60 cm. Overhead sinks (and, accordingly, cabinets) are most often used in sizes of 50, 60 and 80 cm in various variations.

50×50 cm;
50×60 cm;
60×60 cm;
50×80 cm;
60×80 cm.

Washing width may be 50 or 60 cm (sometimes 55 cm), the size of 80 cm will be too wide and inconvenient to use (you will have to reach for the tap). Wash length varies in wider sizes and depends on the presence of a monolithic countertop. If there is a table for dishes, then the length of the sink reaches 80 cm, if there is only a bowl, the length of the sink will be 50 or 60 cm.

bowl depth can be 16, 18 and 19 cm, while 19 cm will be more convenient for washing, since the walls of the sink will better restrict water from splashing onto walls and clothes.

How to properly install a countertop sink? The installation of the overhead sink is carried out in two stages: first, the support cabinet is assembled, then the sink is mounted on it.

How to install an overhead sink on a cabinet (video):

Like any cabinet furniture, the sink cabinet is delivered unassembled after purchase. The package contains cabinet walls and fasteners (corners and self-tapping screws). The body parts of the pedestal are rectangles cut from a chipboard sheet of the required dimensions with machined edges:

two sides;
three tsargi (transverse sticks that ensure the rigidity of the structure);
two doors;
fittings (four hinges and a door handle).

Drawers are located between the side panels in the following places:

front bottom (under the bottom);
front top (under the sink);
back in the middle.

To assemble the cabinet, you will need a screwdriver. The details of the cabinet are assembled using metal corners and self-tapping screws. Sequencing next:

Dismantle the packaging, remove the packing material and lay the parts on the floor.
We assemble the sidewalls and the front sides: first the lower, then the upper sidewalls are fastened to each sidewall at the corners.
We collect the bottom in such a way that its edge lies on top of the lower front side. The bottom is attached to each sidewall and to the lower front side.
We install the back tsargu.

Further installation of the cabinet will consist in hanging the doors. It is performed after installing the sink on top of the cabinet.

Attaching a countertop sink to a pedestal

The sink is turned upside down and smeared silicone sealant around the perimeter, where the sink will rest on the walls of the cabinet.
Placed on top of the sealant rubber gasket. Next, a second layer of sealant is applied.
The sink is turned over and put on the side walls and the front top drawer side.
From the inside, the sink is screwed with self-tapping screws: through the surface of the side walls from the inside of the cabinet.

The final installation consists in connecting the water supply and hanging the doors on the cabinet. Flexible connecting hoses make it possible to slightly move the sink away from the wall (for ease of installation). The drain is connected to the drain pipe with a flexible corrugated hose. Connection to hot and cold water pipes can be done in two ways:

Special flexible braided hoses.
flexible metal-plastic pipe the corresponding diameter.

The metal-plastic connection is more reliable and durable than the use of flexible hoses.

To evenly hang the doors on the kitchen cabinet, the hinges are first screwed directly to the door, then the door is applied to the sidewall and the locations of the hinges and their holes on the sidewalls are marked with chalk. Then the doors are screwed in turn, applying them to the sidewall and controlling the coincidence of the drawn arrangement of the hinges.

After installation, you can evaluate the convenience of using finished kitchen furniture. Under democratic affordable price(let's rate it at 5 points on a five-point system) the overhead sink is very practical. It is easy to mount, if necessary, disassemble and rearrange to another place (5 points for practicality and functionality of use). The comfort of the sink loses a little, as water can flow between the sink and the back wall, or between the side of the sink and the table next to it. In such cases, it will be necessary to control the presence of water under the sink on the floor, which is especially inconvenient to check in the gaps between the sides of the sink and adjacent kitchen furniture (grade 4, in some installations the quality of comfort is average, grade 3). Reliability in operation of the overhead sink is sufficient, rating 5.

The most difficult thing is to evaluate the appearance of the overhead sink. If compared with marble, the evaluation of the exterior design of a metal sink will be low - 3 points. In comparison, overheads lose in design not so much and can get 4 points.

Corner sink with original design

Among various characteristics and features of installation and operation of overhead sinks, the advantages prevail over the disadvantages. The popularity of the overhead design indicates its significant (for the majority of the population) advantages and not so significant disadvantages, so buying an overhead kitchen sink is the best solution for the average family. Therefore, overhead models are sinks No. 1 in a row.

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

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

So, convenient plumbing was purchased, which fully meets the needs of the owners in terms of practicality and appearance. By the way, stainless steel sinks are popular for the kitchen today. Firstly, they have an acceptable cost, low weight, and are durable in use.

Universal color "metallic" can be combined with a variety of color solutions in room.

Installation is quite simple, there are only two steps:

Assembly of cabinets under the sink;
Installation of a stainless steel sink on a pedestal.

The sink is an indispensable attribute of the kitchen. It can be easily installed with your own hands - for this you do not need to have special knowledge and skills.

Furniture assembly

The first stage requires the preparation of the furniture itself so that plumbing can be installed. Usually delivered to the customer unassembled. If you do not know how to assemble a cabinet for a sink, the instructions included with the furniture will help.

Looks like a diagram.

The standard set are:

2 side walls;
2 doors (or one);
Bottom;
3 frames for rigidity;
Accessories, corners, self-tapping screws.

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

Sink installation: what is needed for this?

How to fix a stainless steel sink on a cabinet so that it holds well and the installation itself does not drag on for a long time? To do this, you need to have accessories and tools, thanks to which the installation of the sink on the cabinet will not be any particular problem.

It is possible to attach the sink to the sealant without additional devices if it is light. If the overhead sink is heavy, then its installation on the sealant will lead to the collapse of the structure. In this case, it is necessary to mount on 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 will 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 just a sealing agent and corners are sufficient.

Installation

Lay out the tools and accessories in advance so that they are at hand. It is also desirable to decide on a mixer and a siphon so that everything is installed immediately, otherwise it will be difficult to install later.How to attach a stainless steel sink to a cabinet? This is not difficult if the steps to assemble the frame itself have already been completed.

L-shaped mounts are installed, both in the kit and purchased separately.

As fasteners, it is better to purchase l-shaped plates with oblique slots in the fastener store. Plates will need 4-5 pieces.
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 a through hole) 0.5 cm higher from the mark, screw in a self-tapping screw and put the mount. Do the same actions in other places of the structure.

During assembly, pay attention to ensure that all holes are at the same level.
Next, a sanitary ware is assembled, a siphon with all gaskets is attached to it, and a mixer is fixed.

Before you install the overhead sink itself on the underframe or cabinet and fix it, you need to assemble it completely - fix the siphon and mixer in their places, install gaskets.
Treat the ends of the walls with sealant. It is needed so as not to protect the furniture from moisture.

This tool provides additional fastening of the sink to the cabinet in the kitchen.
Now you can start fixing- put on a furniture frame, where the fasteners are placed on self-tapping screws.

Fasteners are placed on self-tapping screws and shifted along the slot. This presses the sink against the cabinet.
to do plumbing work for connecting the water supply and drain in the kitchen.

Take care of the accuracy of the work and reliability.
After the attachment of the stainless steel sink to the cabinet is completed, you can check it for leaks. The sink is filled with water. Check if water is leaking from the junction of the sink and siphon.

If water leaks out, then the system is assembled incorrectly.
Installing kitchen cabinet doors- the final stage, which will become the final point in plumbing work.

The sink is attached to the cabinet with fasteners and a hermetic agent. This is the most reliable way, durable enough.

So the question of how to install a stainless steel sink on a cabinet has been resolved. With proper performance of work, it is able to stand for a long time.

Many 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 stipulated. Then there will be little work with the installation of the sink.

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

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

Remember that the gap from the edge of the countertop to the edge of the sink must exceed 50 mm. If this distance is less than 50 cm, then the sink must be deepened.
Make a hole at the corners of the outline.

In order to make a hole in the countertop, you need an electric jigsaw.
Glue masking tape from the outer side of the contour so that the surface around it is not damaged during work. Before cutting the opening, fix the part to be removed from below so that it does not damage the surface under it when it falls.

To avoid chipping on the front surface, choose the opposite direction of the tooth.
Treat the ends of the countertop with sealant, assemble the complete plumbing elements (faucet 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 flagellum in thickness just above the side of the sink.
Fix with clamps (included in its package when buying).

The sink must be inserted into the hole and the edges are pressed firmly so that the silicone bundles take the shape of the sink, and leave for a few minutes.

So, having considered how to fix a stainless steel sink on a cabinet with fasteners and on a countertop, you can see that doing this is not as difficult as it seems.

The hardest part is getting the hole right. If it turns out to be more than it should be, then the paws will not be able to hold the sink.

Sealant selection

big role in installation work plays a sealing material. The following types of funds are on the market:

silicone acrylic;
Elastic silicone;
Polyurethane silicone.

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

The agent is applied to a dry, cleaned surface so that there is maximum adhesion. If the surface is not fully prepared for sealing, then moisture can penetrate into the cracks, which is fraught with the reproduction of fungus and mold.

A flexible silicone sealing material is usually used. It is easy to use and quite reliable.

Summing up

Benefits of installing a do-it-yourself sink:

There are tools in almost every home, fastening the overhead sink to the cabinet can be done with almost improvised means;
You can save on professional plumbing by doing the steps yourself;
If there were no fasteners included with the plumbing product, then it is not a problem to purchase them.

If you can’t install plumbing yourself, then it would be better to turn to professionals.

1 Ergonomics in the kitchen

Food preparation should be accurate and fast. This is primarily influenced by the location of kitchen furniture and appliances. In accordance with the principles of ergonomics, kitchen equipment must be arranged depending on the order of work, that is, from left to right: refrigerator, Dishwasher, sink, stove, and between them work surfaces with cabinets.

Minimum distance between individual devices should be:

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

For right-handers, the most convenient is the placement of individual workspaces from right to left. Regarding the sink, this means that the sink should be on the right and the dryer on the left.

It is best if the sink is mounted 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:

Spaciousness. It determines the number and size of daily washed dishes.
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.
The convenience of use. You should 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 the interior of the kitchen. The sink must match the style, design, color scheme and, of course, the size of the entire kitchen.

In terms of installation, there are two main types of sinks:

superimposed on the kitchen cabinet (overhead),
built into the kitchen worktop (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 chipboard, this is not big problem, but if the countertop is made of stone, conglomerate or composite, then you cannot do without special tools for cutting.

MATERIALS USED FOR THE PRODUCTION OF SINKS

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.

Mortise sinks are made from stainless steel, mineral epoxy composites and hard plastics.

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

WASHING SHAPES

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

3 Installation of a surface sink

The overhead sink is designed for installation on standard pedestals with a standard width of 50, 60, 80 cm. For installation, you need: a tape measure, a screwdriver, 4 wood screws, clamps for an overhead sink 4 pcs, sanitary silicone.
Installation is carried out after installing the cabinet in the place chosen in the kitchen.
We determine how far the sink should hang over the front wall of the cabinet. Subtract the second dimension from the first and get the distance where the screws should be screwed.
We screw the screws into the upper part of the walls of the cabinet - 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 enter the round fragments of the holes.
Push the sink towards the wall so that the screws lock at the end of the base.
Check if the sink is firmly inserted; if it moves, remove it and tighten the screws.
Insert it back into the cabinet.
This installation method ensures a stable installation of the sink. If there is a metal apron on the back of the sink, it should rest firmly against the wall.

4 Installation of a mortise sink

Mortise sinks are designed for installation in kitchen worktops.

The first step is to cut an appropriate hole in the countertop. In wood and laminated worktops particle boards cut the hole with a jigsaw on wood.

For countertops made of stone, conglomerates or composites, special devices are used when cutting holes, so this service must be ordered at the time of purchase. In this case, it is necessary to indicate the dimensions of the hole and the exact place 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 is used for stable installation of the sink. Some sinks come with a sample sink hole that you only need to draw on the countertop.

2. Cut a hole in the countertop with a jigsaw.

3. Insert the seal under the sink, which is included with the sink.

ATTENTION

Wooden and laminated worktops must be protected from moisture after cutting the hole. We cover the edges of the cut hole abundantly with sanitary silicone. After it dries, you can proceed with the installation of the sink.

Steel sinks are fixed in the hole with clamps. Top part fasteners are attached to the holes drilled in the sink apron. The lower part rests against the bottom of the tabletop. Both parts are connected with a screw. Tightening the screw, clamp the mount and fix the sink in the hole.

4. After centering the sink in the hole, fasten the first fastener. We do not twist it to the end, leaving a little free.

5. In the same way, we fasten the mount located opposite.

6. In turn, carefully fasten all the fasteners.

7. The last stage of installation is to tighten all the screws in turn so that the sink rests on the countertop with its entire contour.

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

9. We screw the clamps into the designated places. They can be from 6 to 12 pieces.

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

11. We fix the sink by carefully inserting it into the hole in the countertop. First, the countertop will rest against the edge of the apron on the tabs of the latches.

12. We squeeze the sink in the places where the latches are mounted. The tabs will snap into place in the recesses made on the sink apron. After fixing is completed, you can proceed with the installation of the mixer and the siphon for draining.

ATTENTION

Precise latches and a precisely cut hole ensure that the sink is properly fixed.

Reliable fastening of the kitchen sink to the countertop, cabinet or other structure is a guarantee of long-term operation of the plumbing fixture. Achieving a rigid fixation of the product is possible only if the process is approached correctly, in terms of using the installation method corresponding to the model of the installed sink. Therefore, fasteners for sinks to a countertop, cabinet or console are determined by the model of the plumbing fixture.

Types of sinks for washing

The lineup kitchen sinks represented by a huge range household appliances, differing not only in dimensional indicators and design, but also in the method of installation and fastening. So, according to the installation method, such models of kitchen sinks are distinguished as:

Desktop. These sinks are installed on top of countertops. kitchen set, to which are attached at the level of the siphon of the drain structure. This type of sink is rarely used in kitchens. In bathrooms, these sinks are found as premium appliances. Therefore, they are priced accordingly.
Overhead. Devices of this type are installed on floor cabinets. In the design of the shells there are sides that serve as support planes. The device is laid on them, leaning on the upper ends of the cabinet walls. Most often, these models are made of stainless steel, hence the low price of the product.
Mortise. Structurally, a device of this type is “recessed” into the countertop of the kitchen set, to which it is attached from the back of the plane with special fasteners. The installation process is associated with cutting out a part of the countertop exactly to the dimensions of the sink.
Underbench. Such sinks are installed just below the front surface of the countertop. These models are usually placed in countertops made of stone (natural or artificial). For their fastening, special brackets are used, and the ends of the devices are treated with a special adhesive, which not only glues the sinks to the countertop, but also creates a tight connection between the planes.
Integrated. Basically, such sinks are made of synthetic stone, less often of stainless steel. The main installation condition is the minimum clearance between the appliance and the worktop.

Attention! Underbench and integrated models are installed only by professional plumbers. This is due to the fact that the installation of such sinks is a complex process, which is based on an exact fit to the countertop. Therefore, it is better not to carry out such installation on your own.

Installation technologies

The easiest way to install is to mount the surface model.

The floor cabinet of the kitchen set is set in a horizontal plane with the help of a short building level.
If landing dimensions plumbing fixture comply mounting parameters pedestals, then the installation and fastening of the first is carried out on silicone sealant. To do this, the upper surfaces of the ends of the cabinet are treated with a sealant, on which the sink is installed. It is pressed harder against the ends, for which some kind of load is placed inside the bowl. After 12 hours, the device is connected to the water and sewer networks and operates in the desired mode.
There is a so-called regular mount. These are special brackets made of metal or plastic. They are installed on the inner walls of the cabinet with a self-tapping screw, which at first is not completely screwed. A bracket is put on it, pressing the top shelf of the sink to the ends of the cabinet. By shifting the bracket along the direction of the bevel angle, a tight pressing of the sink against the cabinet walls is achieved. After that, the screw is screwed to the end. Plumbers advise all work on screwing fasteners to be carried out with a screwdriver, and not with a screwdriver or drill. This is due to the fact that strong pressure on the thin metal of the sink leads to its deformation. The photo below shows this option.
Almost the same option as the previous one, only instead of brackets for attaching the sink, wooden blocks and furniture corners. The sink is planted on bars, which are pressed from above with hands, and the corners are installed on the bar and the wall of the cabinet. The connection is made with self-tapping screws.

Mortise structure installation

First of all, a cutout is made in the countertop for the sink. To do this, use the template that comes with the sink. If there is none, then it is made by hand. To do this, the shell is turned over and placed on a cardboard sheet. A line is drawn along its perimeter, which will indicate the shape of the hole. It is either round or rectangular.

Further, the same line is drawn inward from the applied line, showing the shape and size of the landing area. Application distance - 1-2 centimeters. On the second line, a hole is cut in the cardboard. After that, the template is applied to the countertop at the exact location of the plumbing fixture, a stroke is made on the surface, along which holes for the sink are cut.

The easiest way to cut out is to drill a lot of through holes along the perimeter of the applied line with a small drill with a diameter of 6-8 millimeters. An electric jigsaw blade is inserted into one of them, which cuts the material around the perimeter. If the countertop is made of laminated chipboard, then many holes do not need to be made, since this is a rather soft base, and the jigsaw will easily cut it.

Further, all cut planes are treated with silicone sealant, and a butyl tape is placed on top of the countertop along the perimeter of the cut hole. Both seals are designed to seal the joint and perform additional waterproofing functions. Now the most important point– sink attachment from below. For this, a special metal bracket is used, consisting of two parts: a clamp and a holder. The first one has teeth at the end, which, when pulled together, will cut into the material of the countertop and prevent the fasteners from moving. The second end is installed in the side of the sink, holds it, and when the screw is tightened, it presses the product to the plane of the table.

Both parts of the fastener are interconnected by a screw, often spring-loaded. By screwing or unscrewing the screw, the clamp is strengthened or loosened, respectively. In this case, the connection between the two parts is hinged, that is, the lower clamp rotates relative to the upper holder, which simplifies the installation of fasteners.

The bracket is made of metal: stainless steel, galvanized. Manufacturers today offer fastener with plastic inserts. It is clear that metal products are stronger. As in the case of overhead sinks, all threaded fasteners are screwed in with a screwdriver.

Rules for the installation of stone sinks

Sinks made of stone or granite and quartz agglomerate today are used in great demand. They are heavy, so during installation they have one important advantage over other models: pressure on the countertop, which ensures a minimum gap between the planes of the sink and the table. Therefore, the main thing is to accurately set the surface of the countertop of the kitchen set in a horizontal plane. Then all cut planes of the hole for the plumbing fixture are treated with silicone sealant or any other similar material. The main task is to conduct a thorough waterproofing.

After that, the sink is installed in the hole and pressed. Plumbers recommend immediately checking the horizontal installation building level. After 12 hours, the device can be operated, but first it will have to be connected to communication networks. No fasteners, the sink will hold firmly on the countertop due to the weight and sealant.

Conclusion on the topic

The question of how to properly fix the sink on the countertop is asked quite often. Home craftsmen are looking for simple but effective solutions with which you can independently carry out this assembly process. In any case, the main requirement for the installed sink is its rigid and reliable fastening.

If for the first time you are faced with the question of how to fix the overhead sink, then this instruction will definitely help you. Believe me, the installation of the overhead version is much easier than the mortise one. Here you do not have to equip a seat in the countertop itself. It will only be necessary to fold the frame from the side facade panels, attach the front door and place the selected sink directly on top. But let's look at everything in sequence.

Preparing for installation

Before installing the overhead sink, you need to carefully mount outlets for each siphon and mixer on it. When the structure is fixed on the cabinet, it will be much more difficult to do this.

Chipboard boards require additional protection. If the upper ends are not treated with silicone, then a water-repellent barrier will not form and over time the frame will simply swell and deform.

The process of installing a mortise sink in a countertop can be reflected in the form of a step-by-step diagram:

Step 1: contouring seat. We make a template from a dense material in the form of a purchased sink, leaving an allowance of 1-2 cm, and try it on the countertop.

Step 2: Position selection. Using the template, we determine the exact configuration of our element on the countertop. When choosing a position, we take into account the general organization of the space adjacent to the sink, think over how convenient this or that position is. Circle the stencil.

Step 3: Protecting the table. We cover the area around the proposed hole with masking tape to prevent scratches and other damage.

Step 4: We are working on the landing area. With a drill, we make the starting points for cutting (drill 2mm), connect them with a chisel and turn them into a slot. We cut along the contour with an electric jigsaw, observing the perpendicularity of the cut.

Step 5: Installation. We apply sealant to the resulting cut and, pressing, insert the sink. Removes excess funds, give the composition 10-12 hours to gain a foothold, connect water supply and sewerage.

Use of mounting brackets

Installing an overhead sink requires a little less time and can also be done using special metal corners. They usually come with it. In total, at least 4 mounting plates are required, which will be fixed on the outside of the cabinet with self-tapping screws. Since the wall of the cabinet-stand rarely exceeds a thickness of 18 mm, the screws in the set are 16 mm long.

The step by step process looks like this:

We screw in the screws by 5-6 mm.
We hang a mounting corner on them (with the inner corner part to the cabinet).
We clamp the screws, but not completely, leaving room for adjustment.
We put the sink on the stand so that the powerful main fastening screw is fixed in the very depths of the metal corner.
We clamp the screws until they stop and make sure that the fixation is secure

We fix the sink with glue

Installation of a surface sink is possible with the use of glue. But this method is only suitable if the underframe almost perfectly matches the sink itself. It will be placed on top, and the ribs will "sit" on the cabinet.

Advice! Do not spare the sealant on the entire contact surface. It plays the role of glue and additionally protects the joints from the penetration of moisture into them.

Installation with wooden blocks

You will have to think about how to fix the surface sink on wooden blocks if there are no mounting brackets at hand or defects are found on the surface of the cabinet frame. So what do we need?

bars, right size;
furniture corners;
small nails or screws.

The first step is to build a mounting platform in the form of a rectangular frame. It will serve as the top frame of the stand. It is he who will smooth out all the bumps. The assembled bars are sent to the overhead sink box and fixed there steel corners along the perimeter. And we put the already received design directly on the cabinet. We will fix it with the help of the same corners, but from the inside to the walls.

Final work

Important! If, after reading the instructions, the entire procedure is already clear to you, then you can proceed with the installation, otherwise we recommend that you see how to fix the surface sink in the video tutorial.

At the final stage, it remains to attach the siphon to the sewer pipe. And we connect flexible connections from the mixer to the source of cold and hot water supply. Now you can safely open the shut-off valves and use the mounted device. For very lazy plumbers, there is another way out. Fasteners for an overhead sink may look like ordinary hooks for hanging it on the wall. But in this case, appropriate holes must be made on the back of the sink. And you can simply put the cabinet under the sink separately.
