Step-by-step instructions on how to securely attach the sink to the cabinet

Preparation of materials and tools

Before installing an overhead stainless steel sink on the cabinet, you should prepare all the necessary tools and consumables. Here's what you'll need to get started:

• Screwdriver or screwdriver.
• A hacksaw, if the pipeline is open, is laid along the outer surface of the wall. In this case, you will need to cut out the walls of the cabinet so that you can move it tightly against the wall.
• Flexible meter, ruler, angles, level, if you need to check the horizontal installation.

You won't be able to install a sink without tools.

Selecting a sealant

The sealing material plays a major role in installation work. 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.

Making a kitchen sink cabinet

There are 2 options for this method of installing a stainless steel sink:

1. When buying a cabinet or a complete set of kitchen furniture. In this case, the section that will be fixed in the place of the room where the sink needs to be installed must be open at the top. That is, it is a cabinet with a frame, side walls, front doors and a bottom.
2. The second option is to make your own cabinet.

Naturally, for the second option to resolve the issue you will need to acquire:

• Lumber - this will be timber, the cross-section of which should be about 10x20 mm.
• MDF, chipboard, fiberboard for creating sides, bottom and doors.
• Metal corners.
• Screws for connecting elements.
• Additionally, glue may be needed.

To make your own cabinet you will need chipboard and other materials and tools.
After this, a drawing is selected in accordance with the dimensions of the stainless steel sink that is planned for purchase.

At this point, it is important to consider the following parameters:

1. The sink can be simple, that is, it can consist solely of the bowl itself. Most often, the dimensions in this case along the upper plane of the cabinet will be 600x500 mm. And the height is standard 850 mm. Although there are other options for the height of the working surface.
2. The second option is a sink that has either a double compartment or a drainer that is located either to the right or left of the main sink. In this case, the dimensions on the upper plane are 600x800 mm.
3. The depth of the sink most often occupies 150 mm.

The drawing must take into account certain parameters.
When making a cabinet yourself, first:

1. Select a suitable drawing.
2. Then the amount of materials needed is calculated. They buy them.
3. The cut is made in accordance with the dimensions in the drawing.
4. The frame is made of timber.
5. Then, using screws, the sides and bottom, as well as the back wall, are attached to the frame.
6. Using metal corners, individual elements are fixed relative to each other. This eliminates distortion of parts during operation and exposure of furniture to loads.
7. After this, the doors are sawed and trimmed at the end with a special edge in order to fix the open edge.
8. Then they are hung on hinges that are attached to the sides.
9. It is important to take into account that along the upper plane, in the place where the stainless steel sink will be installed, there should be strips around the entire perimeter. It is on them that the shell is hung, as it were. They serve as a support for her.

Distinctive features of overhead models

If we do not take into account sinks that are a thing of the past, which are attached directly to the wall on special brackets and do not require a cabinet or countertop as a support, all products for washing kitchen utensils can be divided into 2 categories: overhead and mortise.

The main difference between the two types is the installation method. The first ones, chosen exactly to size, are “put on” the top of the cabinet, and to install the second ones, you need to cut a hole in the tabletop.

From here follow the distinctive features expressed in design, material, and shape.

Products that do not require additional processing of the base are preferable for self-installation, and they are on average cheaper.

However, design features rarely allow the use of “overlays” in modern kitchen sets with a single countertop and built-in appliances. Overhead models are also quite often chosen for installation in the bathroom, but these plumbing fixtures have a more attractive design, material and size than kitchen fixtures.

For installation, you need a separate cabinet without a table top, which you can make yourself by cutting parts from a sheet of laminated chipboard or MDF and connecting the parts with self-tapping screws

But there are similarities between the two types of sinks. For example, installation of a tap and siphon, as well as connection to water supply and sewerage, is carried out using the same technology.

Preparing the sink

Once you have a cabinet on which the overhead sink will be installed, you should first prepare it for the installation process.

Before installation, the sink must be prepared.

To do this, you need to perform the following manipulations:

1. Unpack the metal product. The packaging film must be removed very carefully so as not to scratch the surface. Especially if it is glossy.
2. Carefully try it on the cabinet and make sure it fits snugly enough. It is important at this moment to analyze whether the sink fits too tightly on the sides and, conversely, whether it is wobbly. If it doesn’t fit, you will have to sharpen the sides a little in the place where it is necessary. If, on the contrary, it dangles too much, then you will have to glue thin wood chips onto the sides.
3. After this, to ensure long-term operation, care should be taken to ensure that the ends of the lumber are protected from moisture. To do this, they are treated with special materials that repel liquids or covered with a special edge film.

Installation of tap and siphon

Installing a siphon without experience is not so easy. Therefore, those who have not had experience in such work should use the step-by-step instructions provided:

1. A gasket must be attached to the bottom of the siphon. Then screw it on.
2. The following parts must be attached to the pipe in strict sequence - a plastic nut and a cone-shaped gasket.
3. Combine the pipe with the flask.
4. After this, tighten the nut. Do this very carefully.
5. Next, the pipe should be connected to the siphon using a coupling nut.
6. The cone-shaped gasket must be fixed on the reverse side, and this part is connected to the sewer.
7. A gasket is also placed in the drain hole. An additional metal mesh is fixed here.
8. Then we fix the screw and attach the pipe.
9. At this stage, you should make sure that there are no distortions, and also make sure that the pipe does not touch the bottom in the sump. Otherwise, draining will be difficult or impossible.

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.

The standard set is:

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

1. The side walls and front frames are connected with screws and corners. One of the frames is attached from above, and the second from below.
2. Add a bottom to the structure, which rests with the front edge on the lower frame.
3. Next, the rear frame is attached.
4. The doors are installed last. This is done after installing the sink.

Sink installation

Immediately after assembling the cabinet and installing the siphon, you should begin installing the stainless steel sink. This is done by the following steps:

1. The metal product can be secured using special fasteners.
2. But each of them must be fixed to the cabinet body. This fastening is done using 2 self-tapping screws. They are driven along the inner surface, but it is worth retreating about 10 mm from the top edge of the cabinet.
3. After this, a thin layer of sealant is applied along the inner edge of the metal product. It will allow you to securely attach 2 structures to each other.
4. At the same time, if the upper end edge of the cabinet is not yet sealed, then it is worth covering it with sealant.
5. Then a gasket is fixed to the inner surface of the sink, which will ensure a tight fit.
6. After this, the sink and cabinet are assembled.

The situation is more complicated with the installation of a built-in sink if you have purchased a cabinet with a countertop. In this case, you will have to make a cut along the top plane so that the sink can be attached. This method is more labor-intensive.

Floor standing vanities with factory installed sink. They are as easy as possible to install. They do not require additional fastening systems. The structure can stand on legs or be equipped with a plinth. When arranging the latter, less dust and debris will accumulate under the bedside table. If you choose the option with legs, then there will never be problems with adjusting the required height of the sink.

Wall-mounted options will save space on the floor, since they do not come into contact with its surface at all. However, such structures should be installed only after making sure the strength of the wall. For such a set you need strong brackets that will hold the dowels in the wall.

Corner structures have a large capacity, but do not take up much space. The washbasin bowl itself is located in the middle and is held in place using internal fasteners provided by the manufacturer. The maximum that the user needs to do is to install such a headset at a level and connect it to communications.

Connection to water supply

To connect to the central water supply, special flexible hoses are used. It is better to give preference to reinforced ones, since they are able to last a longer period of time without changing their characteristics or failing.

Connection occurs using flexible hoses.

It is important to calculate their length so that it is enough from the place where the tap is fixed to the point of connection with the central pipeline. The hoses will be secured using nuts. They must be supplemented with washers with a seal to prevent leakage.

The hoses are secured with nuts.

When this method of connecting to a water supply is carried out, when tightening the nut, try to feel the moment when it is necessary to stop applying force in order to prevent damage to the thread. In addition, it is important not to overtighten the nut so that if the connection begins to leak, there will be a thread left to tighten it more tightly and eliminate the leak.

How to attach it correctly with your own hands

In order for the sink installation process to go quickly and efficiently, you need to choose the right sealant. This will allow you to reliably and permanently protect your sink from prolonged exposure to moisture. In addition, to successfully install an overhead sink, you will need the following tools:

• electric drill;
• Screwdriver Set;
• pliers;
• silicone sealant;
• ruler;
• wood drills;
• self-tapping screws;
• masking tape;
• L-shaped fastener.

Secure to the tabletop

For these purposes, it is important to adhere to the following action plan

1. It is necessary to draw the contours of the future sink on the countertop. For this spruce, a regular pencil will do. Be sure to take care of the indentations from the front and rear edges of at least 5 cm. After this, you can take measurements where the bowl will be concentrated. Using these measurements, it is worth drawing the outline of the hole for the sink.
2. the line along which the cut will take place should extend 1 cm outward from the sides of the bowl. Make a hole at one point of the contour. If the shape of the bowl is in the form of a rectangle, then the hole should be made in the corners of the designated contour.
3. Attach masking tape to the outside of the outlines. Thanks to it, it is possible to protect the tabletop from damage that a jigsaw can cause to it. In the process of cutting the opening, it is necessary to screw self-tapping screws into the cut to a small depth. Thus, it is possible to protect the inside from falling. The element to be removed should also be secured from below with support.
4. Treat the ends of the table top along the saw cut using silicone sealant. This way you will protect your products from moisture. Application of sealant is also possible along the drawn perimeter.
5. Insert the sink and installed mixer and siphon into the prepared opening. Secure it to the tabletop using clamps. These fasteners are included in the plumbing fixture complex. All that remains for you is to connect the mixer to the water supply and drain the product through the sewer siphon.

Here's a video of attaching the sink to the countertop from below:

Mounting on a kitchen cabinet

In this case, the DIY installation process is carried out as follows:

1. Prepare the place where the bowl will be installed. It is worth turning it upside down and tracing the outline with a pencil. You can cut the hole using a jigsaw.
2. To prevent the embedded part from falling prematurely, it must be secured with 2-3 self-tapping screws.
3. After this, try on the sink to the resulting hole. If it is placed normally, you can attach it to a set, equip it with a siphon or mixer.
4. Attach the faucet to the bottom using nuts and washers. Screw flexible hoses into it.
5. The siphon is assembled using union nuts. When the sink is equipped with an overflow, it is also worth connecting it to the siphon. Although it is not uncommon to find ready-made siphons for sinks with overflow. The finished sink is installed in a prepared place, and then connected to the water supply and sewerage system. Seal all existing spaces with sealant.
