Selecting a sink

In the plumbing market you can buy wash basins on a pedestal, suspended, overhead and recessed. The last product is an integral part of the interior in the bathroom or in the kitchen. The overhead sink is installed on the countertop, which can be replaced by any flat, flat surface. Specialized stands are produced for this purpose. From conventional analogs, they are distinguished by the presence of a depression. The application of such an installation has advantages and disadvantages.

Experts consider the pluses:

  • absence of joints (guarantees protection against leaks);
  • The surface of the table top is suitable for storing accessories and bathing accessories;
  • The design can be placed above the washing machine.

The pipe to the overhead sink is supplied in the same way as to the hanging structure. Experts distinguish several variants of embedding of overhead sinks:

  • drowned in a curbstone;
  • towering in part;
  • installed at the top.

The drain valves are placed in the countertop under the sink. This will require a drill, a hacksaw (electric jigsaw), pliers, a screwdriver, a clamp, a sealer brush, a spatula, a silicone sealant, a pencil, a ruler, a clean rag.

Installation work

The marking in the place of installation is made according to the template that comes with the plumbing. Otherwise, the contour is drawn independently. When determining the location of the sink in the bathroom with the countertop, you will need to follow certain rules:

  1. The sink is not installed close to the wall.
  2. The product can not be placed on the edge of the countertop.
  3. Plumbing should be easy to use.

In the countertop under the sink, a hole is cut with a jig saw, and the product should not fall into it. To do this, it is necessary to secure a strong fastening. The sink is turned over, stacked on the countertop and circled around the contour with a pencil. Then you need to measure (to determine the distance from the edge of the sink to the eyes) for the fasteners. A certain value will indicate the distance that it will take to move away from the described contour inside.

Experts recommend to make an indentation of 1.5 cm inside from the outer contour, drawing an additional template. The formed figure is sawed out. To do this, use an electric jigsaw. With its help, you can cut the hole quickly and neatly. Using a conventional hacksaw will require later corrections of irregularities along the edges.

It is recommended to drill a hole along the inner edge of the contour (as close to the marking as possible).

The rest of the product is sawn off.

Experts advise to press not too strongly on the decorative countertop (to protect against chips). The edges are recommended to be treated with silicone gel, and the end surfaces - sanded using a file and sandpaper. Aligned areas must be covered with a layer of sealant with a silicone base. It is necessary to carry out this procedure carefully, so that there is no leakage during the operation of the sink in the bath. The sealant used should be suitable for working with the material from which the table top is made. If the bathroom is equipped with wooden and plastic structures, then apply sealants, which include alcohol.


The sink is installed in the countertop after filling the ends with silicone. It is necessary to firmly seat the sink. Silicone, squeezed out during the planting of the structure, is removed with a cloth, and the sanitary ware is left to solidify the lubricant.

The next stage involves the assembly of all parts of the structure. It is especially necessary to mount the mixer. Difficulties do not arise if the hole for it is made in the process of manufacturing the shell. The missing hole for the mixer requires its cutting in the countertop. To conduct this procedure is necessary at the stage of preparing a niche for the installation of sanitary ware.

Then you should install the hoses into the mixer. The finished product is inserted into the hole with the sink installed and securely fixed with fasteners. After installing the fasteners, it is recommended to tighten them tightly. Then connect the drain valves.

The installation of a sink in the counter does not require special skills. However, poor-quality mounting of the product in the countertop can ruin the interior of the bathroom, becoming the main cause of structural failure (due to regular moisture penetration into the slices).

If necessary, the installation of sanitary ware is made by specialists.
