How to calculate the number of tiles for the bathroom

People, who at least once in their life were engaged in laying tiles in the bathroom or any other room, know how time-consuming this process is. And it is not even in the laying of tiles on the floor and walls, but in carrying out preliminary measurements and calculating the materials required for laying. During the calculations to calculate the amount of materials needed to repair the bathroom, it is important not only to correctly measure the area that will be covered with tiles, but also to calculate the stock of materials.

Boxes with tiles

You may ask why it is necessary to have a stock of tiles. And its necessity is that in the case of a large number of cutting operations, the probability of getting a defect increases much more. The quality of the material also has its effect on the consumption of tiles. Experts say that the most acceptable amount of material reserve for laying is 10% of the required minimum. How to correctly calculate the materials in order to lay tiles in the bathroom, you will learn in this article.

Measuring the area

First of all, when calculating the required amount of material, you need to know the area of all the surfaces to be treated in the bathroom. This is a fairly simple process that requires a responsible approach.

The algorithm for calculating the area of the working surface is quite simple:

  • To calculate the total area of the walls, you must first measure the length of each wall, add up all the values and multiply by the height of the ceiling. As a result, we get the total area of the room.
  • Be sure to determine the dimensions of the doorway and window. And if there are also niches and protrusions in the bathroom, you also need to know their dimensions.
  • After that, it is necessary to subtract the value of the area of doorways and windows from the total area of the whole bathroom. Thus, we get the value of the surface area that will be covered with tiles. In order to calculate the area of the bathroom floor, its length must be multiplied by the width. In the case of a complex configuration, dividing the floor area into simple shapes can help you calculate its area. Dividing the room into simpler shapes, calculating their area, you can determine the total by summing up the results.

Do not forget to write down the results. The most illustrative will not be just a record, but a drawn on paper plan of the room, where you can also specify the location of furniture and plumbing.

Laying methods and their influence on the number of tiles

After all the measurements are made it is necessary to decide on the method of laying tile units. There are several basic ways of laying tiles on the walls and floor of the bathroom. The choice of one or another method depends on what final effect you want to achieve as a result of the repair and laying of tiles in the bathroom.

Let's consider the main ways of laying tiles.

Regular "seam to seam" with or without borders

With this method, the tiles are laid in rows under each other, parallel to the walls and corners. In addition to the simplicity of this method, it is also very economical, leaving very little waste and scraps during installation.

Diagonal

Diagonal - a more complicated method of laying. The first row is formed of tiles cut diagonally, and the seams between the plates in this case are located perpendicularly and at a 45-degree angle to the wall.

Diagonal method of laying

Tile overlap

This is also one of the simplest methods of tiling, in which each successive row in relation to the previous one is shifted by half a tile. The final pattern in this tiling looks like a brick wall. When installing tiles on the floor in this way, two laying directions can be used - diagonally or "deck" and horizontally or vertically - "braiding".

Checkerboard

This variant of laying is almost the same as the diagonal method, the only difference is the use of tiles of contrasting colors. The result is a surface that resembles a chessboard. Very often this method is used when creating the interior of bathrooms in black and white.

Tile laying in a staggered pattern

There are several other options for laying tiles, but they are used much more rarely, require a high professionalism of the master and a large expenditure of time and materials. For example, the carpet method of laying floor tiles.

Note that the choice of the method of laying tiles has an impact on the amount of material needed for the work.

Basic rules for calculating the number of tiles

Maximally accurately calculate the required number of tiles for the repair in the bathroom, you need to follow a few simple rules:

  1. First of all, you need to determine the necessary parameters of the walls - width, length and height. The size of the doorway, the size of niches and protrusions, should be measured and subtracted.
  2. Then you need to choose the desired size of tiles. Keep in mind that if you use tiles from different manufacturers or from different collections, they may also not match in size.

When the size of the room is determined and the chosen method of laying, calculate the area to be tiled. At the same time will be good to make the calculation of the required number of tiles, in pieces.

To the obtained results must be added about 10% more reserve, to avoid unforeseen moments: the damage to the tiles during trimming or installation, and in the case of a manufacturing defect in the batch.

For walls

Consider an example of calculating the required number of tiles for the walls of the bathroom:

  1. We calculate the number of tiles that fit the length and height of the wall in 1 row.
  2. Multiply the values and get the number of tiles for the wall design.
  3. Add at least 10% for contingencies.

See below for a detailed example. It also takes into account the area of the door opening.

  1. Measurements and calculations for greater accuracy should be made for each of the walls separately. For example, the height of one of the measured walls is 270 cm. and you have chosen a tile height of 30 cm., divide 270 by 30, we get 9 tiles in one row.
  2. Similarly, find out and the number of facing tiles in the width of the wall. Round the received values should be rounded upwards.
  3. Multiply the number of tiles received separately for length and width, thus obtaining the total number of tiles for each wall.
  4. Also take into account the size of the borders, if the tiles will be laid according to the method with the border.
  5. The presence of a doorway complicates the calculation a little. The height of the doorway, assuming it is 200 cm, we divide by the height of the selected tiles, e.g. 30 cm, round down and get the number of tiles in height, which in this case is 6.
  6. In the same way, we find the number of tiles for the width of the doorway, and then the total number of tiles that can fit in this doorway and subtract them from the total number of tiles needed for the entire wall.

Don't forget to add another 10% to the result!

For the floor

The number of floor tiles must also be pre-calculated. To do this, we measure the length of the floor, for example, it is 170 cm, and the width, for example, it is 150 cm. and the size of one floor tile is 33 by 33 cm.

The number of tiles in width, in this case it is 5 pieces, is determined by dividing the width of the floor by the width of the slab with rounding upwards. Also find the number of tiles required for the length, in this case it is 6 pieces.

Multiply the results with each other and add about a couple of pieces as a reserve. If we determine the number of floor tiles required by dividing the floor area by the area of one tile, we get a shortage of working material in the amount of 6 pieces.

Laying diagonally

The methods of calculation described above are used for installing tiles in the "joint to joint" method. To calculate the required number of tiles for diagonal tiling you need to represent it on a piece of paper in a box or on a millimeter paper.

Each wall is depicted separately and draw the necessary pattern. Then just count the number of whole and cut tiles. If two cut parts can be obtained from one tile, in this case you should specify only one tile. After this calculation, add approximately 15% stockpile and you have the total number of tiles for this method of laying.

Calculation of additional elements: borders, pencils

In order to calculate the number of curbs and pencils needed, you need to know the dimensions of the curbs and pencils used and the perimeter of the room, not including the size of the door opening. The number is determined by dividing the perimeter of the room by the length of one element used in laying. During the calculation, note that Twice as many pencils are needed due to the fact that they are laid on both sides of the curb.

Calculating the amount of glue and grout

The amount of tile glue will depend on the condition of the walls and floor, as well as the size of the selected tile unit. If the surface intended for tiling will be fairly even, then the consumption of glue will be small. Glue consumption will increase significantly if the size of the facing tiles is large, because the adhesive layer will need to be made thicker. The average data on the consumption of glue is always listed on the package, so they should be guided by them in the first place.

Tile Glue

To find out the required amount of grout for interstitial joints in kilograms, you should divide half the perimeter of one product by its area and multiply by the width. The resulting number must also be multiplied by the width of the seam (1.5 to 3 mm) and the depth, which is usually taken equal to 1.5 mm. Thus, we get the value of mass of grout for processing an area of one square meter.

Possible errors and mistakes

In order for the bathroom renovation to go easily, you need to be first of all careful in the calculations. Protect yourself from unnecessary hassles and problems - buy enough tiles, it is purchased about 10-15% more than necessary according to the made calculations. It should be remembered that diagonal, shaped and carpet laying will require significantly more tiles than installing "seam to seam" and "spread". When the bathroom has a complex geometric shape, niches and protrusions, their size must also be taken into account. In the number of tiles, of course, it is better to err in the larger side, and then with a shortage of several pieces is not the fact that the copied copies will be from one batch, and will not differ in color and texture with previously purchased tiles.

Programs for calculating online

In our age of information technology, there are many different programs and online services to determine the amount of required for the repair of facing tiles. Online programs are much more convenient, because they do not need to be downloaded from the Internet, they are freely available for use online. Such programs are easy to use and at the same time they give quite accurate calculation results. Very interesting are also 3-D programs that can not only calculate the number of tiles, but also show how will look like the selected pattern of tiling. Also such programs can help to calculate the number of decorative elements.
