Despite the small size of the bathroom, during repair, it can take quite a lot of energy and financial investments. Walls and floors are usually laid out with tiles. This can be explained by the functional purpose of the room - due to constant moisture and temperature changes, another coating can quickly deteriorate. Some owners in the bathroom glue the wallpaper. This is an unreasonable choice, as soon they either fall away, or (worse) will be covered with a fungus. Sometimes the walls of the bathroom are plastered, but this option should not be considered optimal either.

Among all the criteria for selecting tiles in the bathroom you need to take into account its surface. Glossy tiles will be slippery.

The best choice is tiles. Before you start the work, you need to think in advance the shape, color and quantity of tiles. This will simplify the work in the future.

## Requirements for the tile

For floors and walls you need to choose different types of tiles. But there are general requirements for both options:

Layout of the tile in the bathroom.

- the moisture permeability of the coating should be minimal;
- The surface of the tile must be resistant to household chemical reagents;
- the color of the glaze should not fade with time;
- tiles should be resistant to temperature changes.

In turn, floor tiles have a number of features. Since it is constantly subject to mechanical action, it is worth paying attention to its main characteristics:

- high resistance to abrasion and mechanical stress;
- high resistance to bending;
- resistance to fine abrasives.

The last requirement can be explained by the fact that you often have to enter the bathroom in shoes. So that the dust and dirt from the shoes do not scratch the surface, the tiles must be resistant to the influence of such factors.

There are advice and recommendations from professionals how to choose a tile. By sticking to them, you can ease your work several times:

Characteristics of ceramic tiles.

- Gypsum for the bathroom is not suitable. This material absorbs moisture, so this tile on the wall will not hold. And if it does, it will not take long.
- Ceramic tiles of the first grade can last more than 10 years.
- Masters recommend buying tiles from Spanish and Italian manufacturers.
- On the flooring there should be no glaze. It eventually wears off, and the tile loses its appearance.
- In a small room, a huge tile will look ridiculous. But, in turn, in a large bathroom it will be just right.
- When choosing a mosaic, you should pay attention to the fact that its laying will require a lot of effort. It will not be easy to select a drawing.

Particular attention should be paid when choosing the color of tiles. Since this material can last for many years, it is necessary to give preference to a color that will not irritate and will look harmonious with any change of plumbing. Visually help to increase the space of light colors. The use of dark tiles is appropriate only if the bathroom is large enough. As an option - laying dark tiles in a mosaic way, so you can decorate individual zones.

## Required amount

Having defined the color, size and texture of the tile, it is necessary to correctly calculate how much material is required for laying the floor and walls. If it is not enough, then it may happen that the same kind of it will not happen later. There are situations when the same type of tiles in different batches has minor inconsistencies. If the tile is more than necessary, this is an extra financial cost.

To calculate, you need to perform 3 steps, counting thus:

- the area of the room;
- number of tiles;
- количество бордюра (фриза).

**In order to know the area of the bathroom, you need to measure the area of walls and floor.**

An example of calculating the number of tiles.

The floor area is very simple: the width should be multiplied by the length.

The wall area is calculated by the following formula: (A × B) -C, where A is the perimeter of the floor (the sum of all sides), B is the height of the walls, and C is the door area (height multiplied by the opening width).

Knowing these indicators, you need to calculate the amount of tile that is required for the bathroom. To do this, you need to determine the size of the material. For example, it will be equal to 0.25 × 0.33 m. It turns out that the area of one tile is 0,0825 sq.m.

Then you need to calculate the required number of tiles per square: 1: 0.0825. This figure is 12.12 pcs.

For example, the bathroom area is 30 sq.m. On this figure you need to multiply the number of tiles, which falls on one square. It turns out 363.6 pcs. However, this does not mean that there will be enough such quantity. It is necessary to take into account the human factor and architectural features of the room. The resulting calculations for floor tiles should be increased by 15%, and for wall tiles - by 10%.

Counting the required amount of curb (frieze) must be made by measuring the perimeter of the room. Knowing the size of the frieze, you need to divide the perimeter by the length of one border. The results should also be increased by 10%.

It is not difficult to independently calculate the necessary number of tiles for a bathroom.

To avoid problems, it is recommended to seek help from specialists.
