How to calculate the size of bathroom tiles. Mathematics for a fifth grader or how to calculate bathroom tiles with high accuracy. Example of a designer's work

The calculator itself is located a little lower, if you are not interested in the theoretical part, you can. Tiling a bathroom is becoming almost the only acceptable way of tiling the surfaces of sanitary facilities.

In this regard, it is important to know how to calculate tiles for a bathroom using a calculator specially developed for this purpose by our programmers.

This calculation will allow you to purchase materials in the right amount to optimize your expenses.

Similar wall cladding in a room with a bathroom can be laid with the most different ways, the choice of which depends on many factors, including the design of the material, its size and texture.

Of course, one of the decisive factors is the readiness of the performer and his professional training.

Calculate bathroom tiles - calculator

How to calculate correctly with an online calculator - preliminary considerations

The program provides for calculating the need for tiles when laying them in a standard way, that is, in rows parallel to the floor, horizontal arrangement decorative insert(decorum). Despite the large number of dimensions marked on bathroom diagrams, you should keep in mind that not all of them are required to be filled out.

For example, if there is only one window in the bathroom, you do not need to fill in dimensions L3 and L4 or L9 and L10; if there are no windows at all, then the dimensions L1 and l2 are also not filled. If the lengths of walls 1 and 3 (scheme 1) and, respectively, 2 and 4 (scheme 2) are the same, then dimension Lb1 is not filled. If the long walls are unequal, the size of one of the short sides is calculated by the program. Decorative tiles should be laid after a full (not cut) row of the main tile.

“Distance to decor” means the size from the floor to the top edge of the decorative insert, taking into account the number and width of the seams between the tiles. If there is no decor, all dimensions related to it are not entered! If you need to tile sections of the walls behind the bathroom, you should indicate this by clicking on the square button with the corresponding question (under the diagram); a checkmark will appear on the button; You can remove it by clicking again.

THUS, the dimensions Lh, Lb2, Lb3, L5, L6, L8, the dimensions of the bathtub and tiles, and the width of the joint between the tiles are required to be filled in. Size L7 is indicated if the tile will run under the door trim. Size Lb3 may be longer than the length of the bath. The room height (Lh) must take into account the baseboard.

The calculation is carried out taking into account that the tiles are laid from bottom to top, from left to right.

Diagonal method of tiling a bathroom

Using this method, you can stick cladding of any size - both square and rectangular. Great importance when performing work in this way, the performer has professional training and qualifications.

Tiling a bathroom diagonally has a number of advantages and some disadvantages. TO positive aspects The following can be included:

1. The rotated position of the plates in relation to each other visually separates the intersecting planes, creating the illusion of a wider space than it actually is. This is important when finishing is carried out small room.
2. The combination of shades, patterns, drawings on the plates makes it possible to create original design premises.
3. When installed diagonally in the bathroom, the difference in the size of the wall being finished is partially hidden, which is facilitated by the inclined position of the lines.

However, there are also some negative points:

1. Labor intensity and complexity of installation due to large quantity cutting operations. Complex marking, cutting and placement individual parts with an inclination require the master to have some experience in performing such work.
2. When cutting parts diagonally, the corners often chip off, which requires additional refinement of the break with a file.

Preparatory work on surfaces

Before starting work on laying cladding in a room with a bathroom, it is necessary to assess the condition of the surfaces to be finished:

1. First of all, they check geometric dimensions walls Each surface must be strictly rectangular; if this condition is not met, the walls must be leveled, even before installing drywall.

1. Potholes and uneven surfaces on the walls also need to be leveled. Irregularities up to three millimeters deep can be leveled tile adhesive during the installation process. Deviations from flatness up to seven millimeters deep are best straightened using putty.
2. Irregularities with a depth of ten millimeters or more must be eliminated by covering the walls with waterproof plasterboard.

It should be noted that leveling the walls is mandatory before using any finishing installation methods in the bathroom.

And one more general wish regarding surface preparation. Before tiling begins, they must be primed with tile adhesive diluted in a ratio of 1:3. However, this action must be carried out in accordance with the instructions - use tile adhesive, for different compositions requirement may vary.

Diagonal installation of decoration on walls

It is no coincidence that we suggest starting with wall decoration. If the floor finish is laid first during renovation, the rest of the work will have to be done while moving on the new coating, which can lead to damage.

The cost of covering walls with ceramics is not cheap. How to calculate the number of tiles in the bathroom to avoid unnecessary costs? Diagonal placement involves its arrangement as a continuous canvas with cutting out the smallest fragments.

Therefore, this method, despite its high labor intensity, is considered the most economical. Only parts damaged during cutting end up in waste. Therefore, to calculate the coverage for a room with a bathroom, it is enough to calculate the total area of ​​the walls, and, just in case, add about 5% for damage and defects.

The cladding in the bathroom should start from the wall opposite front door. When laying diagonally, you need to start from vertical axis. Laying is done from the starting part in both directions evenly with the installation of spacer crosses along the seams.

They are inserted between the plates, two pieces per side. The thickness of the cross foot is 1.5 millimeters.

The laying technology is as follows:

1. A portion of glue sufficient to install 2-3 plates is applied to the prepared wall surface. The glue is leveled on the wall with a notched trowel; its width should be equal, or better if more format details. The ridge lines on the adhesive layer should not intersect with each other, since an air bubble may form in this place.

1. The tile is placed on the glue and pressed tightly against it. The starting plate must be carefully aligned on the plane: it must be installed at the same distance from the wall along the perimeter. The corners of a part installed diagonally should be placed strictly on the axial vertical line marked earlier.
2. If the plate is skewed, alignment must be done by pressing on it. As a last resort, you can calm it down by carefully tapping it with the striker rubber mallet.
3. The next elements are installed triangular fragments from tiles cut in half diagonally. Plastic crosses are installed in the gap between the plates - two pieces per side. The coincidence of the plane of each subsequent part is controlled by a short bubble level, and the overall flatness is long construction.

1. The upper end of the cladding is formed entirely by cut fragments, so it must be finished with cornice elements. You can select cornices according to size and shape at construction market.
2. A critical operation - cutting a plate - is carried out on special device– tile cutter. You can, of course, use a glass cutter, but it is much more difficult to get required quality cutting.

Diagonal laying of the coating in the bathroom allows you to obtain the most decoratively perfect compositions.

Lay out in a checkerboard pattern

With this method of placing tiles, the seams between the individual plates are located parallel to the intersections of the walls. This method involves cutting the plates to the size of the remaining gap.

This is not economical, especially if they are decorated with an asymmetrical pattern and the remains have to be thrown away. That's why checkerboard laying used for tiles of small diameter and different colors, which allows you to create original compositions.

But before you use online calculator, you need to take all the measurements of the room and get a clear idea for yourself about the design of your bathroom.

How to use the online tile calculator?

This program is presented in the form of a table, into which you need to enter data on your bath for calculation:

1. Geometric parameters premises - length, width of the room and finishing height.
2. Doorway dimensions.
3. Window opening dimensions.
4. Dimensional parameters of the bath.
5. Side walls bathtubs - tile? - "Not really".
6. Selecting a layout type. There are several options: classic, plain - involves the use of tiles of the same color, combined - uses several colors.

Data on the parameters of the bathroom such as the height of the walls, etc. are entered in meters.

The dimensions of the openings for the door and window are subtracted from the total area to be finished.

Dimensions of the bathtub - it is necessary to indicate whether its sides and the floor under the bathtub are subject to finishing.

Layout options:

• classic way provides for finishing the room with material of several colors, separated using a border;
• with a monochromatic finish, the use of decorated inserts is provided;
• in the combined version, the finishing involves the use of plates of three or more colors.

Thus, the built-in calculator provides a wide range of possibilities for realizing your design ideas.

The size of the plates must be indicated in millimeter units. Decorated plates are counted individually.

To calculate the need for materials for curbs, their location along the entire coverage along the generatrix is ​​taken into account horizontal laying, as well as throughout the vertical.

It is also necessary to indicate the reserve of the main material - usually the value is 5-10% of the total quantity.

Laying with offset

This method is used quite often, including in combination with those described above. This method does not bring anything fundamentally new to installation technology.

The calculation of the need for materials remains the same - according to the covered area. This installation method is reminiscent of brickwork and is most applicable when working with rectangular monochromatic tiles.

But the method using mosaic inserts provides an undoubted advantage.

The effect of offset lines makes it possible to make styling defects less noticeable.

Final work

Finishing operations do not depend on the installation method. In any case, you will need to seal the seams between the tiles. For this purpose it is produced special material– grout.

It is usually sold ready-made, packaged in jars. Each manufacturer recommends a certain grade of this material and these tips should be followed.

The grout is applied to the joint space using an elastic rubber spatula. Having collected a little mass on the tip of this tool, you need to rub it into the crack in the transverse direction.

When the gap is evenly filled to its full depth, clean the spatula and use a longitudinal movement to free the surface of the tile from grout residues. Afterwards, you can use a damp sponge and completely clean the surface.

How to take into account door and window openings

In built-in calculators, this calculation operation is embedded in a program that will automatically and correctly calculate the number of tiles that would be placed in these places.

But if the calculation is made independently, it is enough to take into account the total area of ​​free openings and divide it by the area of ​​one tile. The result obtained in pieces of plates must be subtracted from the amount of coating materials total area.

In this case, there is no need to take into account the installation method - remember that about 5% of the reserve is always included in the calculation. It will serve as a compensating factor for the error in the calculation.

Calculate the need for plastic corners

When working, two crosses are installed on each side of the tile. In this case, each pair works on two tiles. The simplest calculation: divide the number of tiles by two and get the required number of inserts.

We multiply the result by 15-20%, since this little thing tends to get lost as work progresses. The costs for them are so minuscule in comparison with the others that it would not be worth talking about them.

Calculate glue and grout requirements

The issue of the need for grout for bathroom tiles can be considered purely theoretically. After all, its quantity is as insignificant as the spacer crosses.

The consumption rate of this material is indicated on the packaging, and you can use these data as a guide when purchasing.

Another thing is tile adhesive. It can be sold as a dry mixture in bags and bags, or ready-made in plastic buckets. Naturally, the consumption rate per square meter is available on the packaging. But this is an average.

The actual consumption may be slightly different, depending on the quality of the surface being covered. If there are multiple places where the tiles have to be leveled due to the thickness of the adhesive layer, the consumption of binder for its installation will be significantly increased.

Any calculation using a calculator is preliminary, as it cannot take into account all the features of your premises. For a more accurate calculation, please contact our managers when placing an order.

1. Dimensions of the room - you must indicate the dimensions of the room in meters.

2. Door size - the area of ​​this area will be subtracted from the total area.

3. Dimensions of the bathtub - you need to indicate the need to lay tiles on the sides of the bathtub and under the bathtub.

4. Layout type - there are options from three types of layout (classic, single-volume and combined).

In the case of a classic layout, the cladding is divided into two parts, which are separated by a border. Wherein Bottom part It has dark colors tiles, top - light colors.

A single-color cladding option assumes that all tiles are laid in the same color with the addition of decorative elements.

For a combined tile layout, several colors are used, usually three.

5. Tile dimensions must be indicated in millimeters.

7. For borders, the number of rows must be indicated. The row is located along the entire perimeter with horizontal cladding, and from floor to ceiling with vertical cladding.

8. At the very end, you need to indicate the supply of tiles you need. The recommended margin is at least 5% (for trimming, accidental chips during trimming).

Finishing a bathroom is a complex process. Except technological subtleties There is also a problem with the design. Baths, toilets, and combined bathrooms are usually tiled. But how to plan its placement on the walls so that the finish is beautiful? For those who decide to do the repairs themselves, there is a good solution - to use software. Eat special programs for laying out tiles, there are such sections in general construction or design software, and there is also online service from large manufacturers and stores selling finishing materials. They will be discussed further.

Tile 6.0

Specialized program for laying out tiles and wallpaper. There are three versions: Home for home use, Profi - for professionals, Profi+Render - professional with extended functionality. For self-creation The design is suitable for Tile 6.0 Home, but it is not free - 1000 rubles per month of use. All of them can be purchased on the campaign website tile3D.com. Naturally, there are hacked copies, but it’s difficult to say how safe it is to download them.

The program in its current version is good: even the stripped-down home version allows you to create three-dimensional projects (3D) and receive calculations based on necessary materials(in addition to whole and cut tiles, he counts the amount of glue and grout for the seams). What else can she do:

• Take into account door and window openings, columns, arches and other curved surfaces.
• It is possible to add new tiles to the directory and save them for future use.
• Tiles can be installed and moved at any angle.
• You can add three-dimensional images of other objects (bathtub, shower, etc.) by specifying their coordinates.
• The program calculates the tiles and Supplies, but in the “home” version you cannot print them, but you can copy them from the screen or take a screenshot and print them as an image, not a table.

In addition, you can change the degree of illumination, shine and relief of the tile. All these settings can be made for each individual object. What else is good - the site has educational form on working with the program, where the creation of a project is described step by step. The program is easy to work with, the interface is clear, and you can master it the first time. One of the disadvantages of the home version is that you cannot get a scan along the walls, which is completely inconvenient. In general, the program is good, but not free.

ViSoft Premium

This is specialized bathroom design software for professionals. One of the functions is tile layout. In the database big number samples - almost 39 thousand types of tiles from different manufacturers(at the time of writing there are 362 of them). The layout project is developed based on the samples that are in the database; new ones cannot be added.

Here is a summary of the program's capabilities:

• Selected tile samples are automatically placed in the specified area.
• It is possible to view other layout options.
• To create a bathroom interior, you can choose plumbing fixtures from a huge database. In this case, the sets are compiled automatically. If necessary, they can be adjusted.
• During the creation process, the project can be turned in any direction, assessing the result from different points.
• Take “snapshots” of the results obtained.

There are two operating modes: drawing and sketch. In the mode the drawing is created black and white image, which can later be “filled” with different colors. Sketch mode - immediately with color.

Ceramic 3D

Good professional software for creating bathroom designs. Naturally, it is not free, but there is a demo version with full functionality that is available to everyone without payment. The free license is valid for 1 month. If you decide to lay out the tiles for yourself, this is a good option, but you must meet the specified deadline.

Ceramik 3D program - available in a demo version for a period of 1 month, it is free

Ceramic 3D allows you to quickly create projects: each operation takes about 2-4 seconds. So simple projects“built” in 5 minutes, complex ones require 15-20 minutes. Here is the set of functions:

• creation of premises of any configuration according to exact dimensions, including attic ones;
• easy drawing of niches, shelves, ledges, boxes of any configuration;
• the ability to create a tile outline of any shape (polygonal, round, etc.);
• drawing of columns and their decoration;
• saving styling patterns of any complexity;
• replacing the contours and dimensions of the room while maintaining the layout;
• the ability to create stairs and decorate them with tiles;
• automatic calculation of the number of tiles.

In general, Ceramic 3D is not only a program for laying tiles. In it you can create the overall design of the bathroom and work out the design of other elements or parts of the room that involve laying tiles. It's nice that the program comes with detailed lessons, with which it is easy to master.

Compass-3D LT

This free version professional program for volumetric design of various objects and parts, created by the Russian company ASCON. So it's not just a tile layout program. This is just one small part of it. The Compass-3D LT version is an introductory version that allows you to master volumetric modeling and planning. The program comes with training materials - videos and graphic examples.

The 3D compass in its lightweight version has very limited functionality, but it is more than enough for laying out tiles. To plan the layout of the tiles during installation, a package with a construction configuration is downloaded (there is also a mechanical engineering configuration). The basic and building packages require approximately 3.5 GB of disk space.

With this program you can:

• make a site plan;
• develop a room design using various finishing materials and evaluate the result in the form of a three-dimensional picture;
• develop unique decorative items and obtain their drawings;
• upon completion of the project, receive drawings indicating dimensions.

In general, the program is multifunctional even in the free version. At the same time, you can master the basics of 3D design.

A simple program for laying tiles without special effects - Arculator 7

If you do not need a three-dimensional image, but just need to look at the layout, and even calculate the amount of material without errors, pay attention to the Arculator 7 program. It is designed for calculating materials for internal finishing works. That is, with its help you can accurately determine required amount tiles, wallpaper, laminate, etc. It is also possible to calculate the amount of materials for ventilated facades. A pleasant surprise: this program for laying out tiles (and more) is free.

What you can do in it:

• Create surfaces of any size and shape, place openings of any shape on them.
• The position of the tiles can be adjusted and rotated at any angle.
• Objects can be located on one surface different sizes in different directions.

Learning how not to work is not a problem even for the least “advanced” user. The interface is clear, the computer requirements are very modest, it takes up less than 1 MB of disk space. Great option, if you only need a layout, and not a design development with the arrangement of plumbing fixtures, furniture, etc.

What else can you work with?

In addition to specialized programs, there are many software, designed for planning other objects, but which has sections for laying out tiles. If you have experience in one of them, it will be easier to work with a familiar interface than to master a new one. Here are some general construction or furniture programs in which you can draw tiles.

• AvtoCad (AutoCad) is a general construction program with wide functionality (2D and 3D available).
• NanoCad is an analogue of the one described above, but it is a Russian development. The basic version is free.
• PRO100 (PRO100). The program is designed for the design of furniture, but there is a solid section for designing the layout of tiles, laminate, and wallpaper. Many people say that it is easier to work in it than in AutoCad.
• SketchUp is a program for designing rooms and furniture; there is a section for tiles, but the functionality is limited and difficult to work with. In addition, you have to manually recalculate the quantity as errors in calculations are common.

Of course, this is not specialized software and it is not so convenient to work with them. But if you have already worked on them in other sections, it will be easier and faster to understand than learning to design in a new program.

Online tile layout programs

Most large online stores selling tiles or manufacturers provide the opportunity to create your own project online for free. The peculiarity is that basically you can only work with those collections that are on the resource. You cannot enter your own data into such programs.

They work on the principle of browser games - there is no need to download and install them. You work through a browser on the campaign resource. The procedure for creating a project is standard: you select or draw a floor plan for which you need to create a tile layout, select a collection (from those that are on the site), then create a layout. Based on the results, a list is usually generated: how many tiles are needed, you can also print or save the layout that you made in the form of a scan along the walls.

Depending on the specific type, the cost of ceramic tiles can reach large values. Its rational use is one of the options for reducing the cost of finishing work. Correct calculations needs -effective method savings Money. How to accurately calculate bathroom tiles and reduce waste? The work should be done in several stages.

First, let's look at the simplest option for finishing bathroom walls - ordinary plain tiles are used for the work.

We will not touch on the decorative side of the matter; we will talk about its characteristics from the point of view of tilers. They love this material very much for several reasons:

• During installation there is no need to monitor the placement of individual tiles taking into account the pattern. This not only greatly speeds up the installation process itself, but also simplifies marking. You can start laying tiles from any corner and place; there is no need to select its position to obtain a symmetrical pattern;

  Such mistakes cannot be made when working with plain tiles.

• tiles can be cut from any side, the segments are used without reference to the location of the pattern;
• It is possible to use pieces of tile from one corner wall to another without preliminary adjustment. Less work and less waste.

We will describe the technology for calculating more complex tile options below, but now we will consider a simple option.

Important. The tiles are sold in packages, in a pack of 0.5 m2, 1 m2 or another quantity (check the number on the package). It is unlikely that any of the sellers will agree to sell tiles individually, in this regard, you should not count the number of pieces, operate square meters. By the way, these calculations are universal and are suitable for determining ceramic tiles various sizes, and they can fluctuate within wide limits.

Step 1. Measure the length of all walls of the room. Use an ordinary tape measure, write down the data in a notepad or on a piece of paper. Add up the total length of the perimeter.

Step 2. Measure the height of the room and round off the resulting values ​​to the nearest centimeter.

Let's look at an example. How to calculate tiles for bathroom walls? First, determine the length of the perimeter. Calculation: 1.5 m+3.0 m+1.5 m+3.0 m = 9.0 m. For example, our ceiling is 2.7 m from the floor. Total surface area 9.0 m x 2.7 m = 24.3 m 2 .

Step 3. From this value, subtract the area of ​​the door and window opening.

The dimensions of the doorway are 2.0 m (height) × 0.9 m (width) = 1.8 m 2. If you wish, then add the area of ​​the platbands to the area of ​​the opening. Their width can vary from five to ten centimeters. But we do not recommend doing this for several reasons.

1. The savings are not so great as to be worth paying attention to. And any calculations may be incorrect, so there is no need to take unnecessary risks.
2. Some types of platbands are fixed to surfaces liquid nails. It's fast and beautiful, no nails or screws are visible. And the liquid glue holds well with smooth surfaces, using it on ceramic tiles is the optimal technology.
3. Not all the walls in the bathroom are smooth; some have to be adjusted under the trim. Why do the same work twice - lay it around the perimeter of the opening ceramic tiles, don't waste your time.

The same applies to the window opening, if there is one in the room, of course. In our example, there is no window, which means the wall area is 24.3 m2 - 1.8 m2 = 22.5 m2. But this is not the final figure yet.

Step 4. Take the dimensions of the bathtub.

If it is installed against a wall, then there is no need to tile invisible surfaces. For example, the width of the bathtub is 0.7 m, length 1.7 m, height 0.6 m. The bathtub will be adjacent to two walls, one at the end, and the second at the side. It is necessary to calculate the abutment area. From the end it is equal to 0.6 m (height) × 0.7 m (width) = 0.42 m 2. From the side it is equal to 0.6 m (height) × 1.7 m (length) = 1.02 m 2. We add these values ​​0.42 m2 + 1.02 m2 = 1.44 m2.

Step 5. We calculate the exact surface area of ​​the bathtub walls for the tiles: 22.5 m2 (without doorway) – 1.44 m2 (junction area) = 21.06 m2, after rounding we get 21 m2.

Important. If decorative screen will be finished with the same tiles, then its dimensions are not subtracted.

As during any construction work, you can’t do without unproductive tile waste. How much stock should I leave? There are several factors to take into account:

• qualified tiler. If a professional works, then 5% is enough. For a beginner total tiles need to be increased by 10%;
• decorative characteristics of tiles. If the tiles have asymmetrical patterns, then the segments cannot be used. The margin must be increased to 10%, regardless of the skill of the performer;
• availability and location of water supply and sewer pipes. When finishing these obstacles, tile consumption may increase.

The tiles can be laid in the standard way (rows parallel to the floor), in a checkerboard, ordinary diagonal and checkerboard diagonal order. Keep in mind that during the checkerboard-diagonal method the amount of waste may increase slightly, but a 10% reserve will be sufficient in any case. At this point the calculation is completed, you can go to the store to buy the material.

wall tiles for bathroom

What to do if there is a border in the bathroom

Step 1. Measure the height of the border and the number of rows of tiles. The height should correspond to the size of the tile.

Step 2. Measure the length of the walls along which the border will be laid, multiply the value by the height. This will give you the total area of ​​the curbs.

Step 3. Calculate the area of ​​one tile, divide the area of ​​the borders by the area of ​​the tile. This quantity needs to be increased by 3–4 pcs. depending on the number of turns.

Calculation example:

• the length of the walls minus the doorway is 9 m (perimeter of the bathroom) - 0.9 m (width of the doorway) = 8.1 m;
• border area for tiles 15 cm high: 8.1 m × 0.15 m = 1.215 m 2;
• the border has a height of one tile of 15 cm. The area of ​​the tile is 0.15 m × 0.15 m = 0.0225 m 2;
• number of tiles. 1.215 m2: 0.0225 m2 = 54 pcs. 2 pcs are enough for stock, buy 56 pcs in total.

If a decorative pattern is planned on the wall, it must be purchased separately. The size of the drawing is indicated on the packaging. Accordingly, this value must be subtracted from the total surface area, and only the missing tiles must be purchased.

Calculation of plastic corners

The use of such corners speeds up the process of laying tiles and allows you to hide small errors made during measuring or cutting tiles. They are installed in internal and external corners, at the junction of the wall and floor. Have different color and sizes, are sold in standard lengths of 2 m and 4 m. They are easy to work with, one side is laid with glue under the tile, and the edges go into the second side freely. This allows you to hide cut irregularities, small chips, etc.

Count it up internal corners, measure their total length. Do the same with external ones. There is no need to round anything out, they will sell it in the store standard length. These elements cost pennies, and you won’t be able to save money on them. Do the same steps around the perimeter of the bath, find out the total length. Do not forget to separately count the number of each type of plastic corner.

If possible, you can also use ceramic skirting boards for bathrooms. In addition to the length, you need to know the number of angles and their type. Professional craftsmen It is recommended to use these skirting boards to finish the junction of the sides of the bathtub with the wall.

Sum up the length and width of the bathtub, find out the minimum footage. The fact is that the length of ceramic borders is standard; they will have to be cut to fit your size. Are being cut decorative elements on a special disc trimming machine. This professional equipment, is quite expensive. It is not economically feasible to buy for finishing one bath.

Calculation of the number of floor tiles

There is less work here, everything can be done in a few minutes. How to calculate how many floor tiles you need for a bathroom?

Step 1. Measure the two side walls of the room. There is no longer a need, the perimeter of the room looks like a rectangle, the sides have the same dimensions. In our case, the length is 3.0 m and the width is 1.5 m.

Step 2. Find out the area of ​​the room. 3.0 m × 1.5 m = 4.5 m 2.

Step 3. If you do not want to tile the floor under the bathroom, then you need to subtract its area. This can only be done in cases where the bathtub has a continuous decorative screen that hides the lower space. The dimensions of our bathtub are 1.7 m by 0.7 m, the area is 1.19 m2.

Step 4. Determine the area open area bath floor. 4.5 m2 – 1.19 m2 = 3.31 m2. Taking into account the reserve, you will need approximately 3.7 m2 of tiles.

Bathroom tile quantity calculator

Why and how to calculate tiles for the bathroom? This is necessary to purchase the required volume of building materials: you will not overpay for unused material, and the money saved can be spent, for example, on purchasing tile adhesive.

Calculation of tiles for bathroom walls

1. Calculate the area. Measure the perimeter of the room and multiply it by the height of the walls. For example, the height of a room is 2.7 m, width 2.5 m, length 3 m. Find the perimeter: 2.5 + 2.5 + 3 + 3 = 11 m. Multiply the perimeter by the height: 11 × 2.7 = 29, 7 m2. The area of ​​the door and windows, if any, is subtracted from this number. Let's say that after subtraction we get an area of ​​28 m2.
2. Finding the area of ​​1 tile. For example, the dimensions of one tile are 0.3 × 0.2 m. Then its area is 0.06 m2.
3. Find out the number of bathroom tiles. The area of ​​the walls is divided by the area of ​​one tile: 28/0.06 = 467 pieces. 10% stock is another 47 pcs. The total quantity is 514 tiles.

How to calculate the number of tiles for the floor

The mathematical calculation of the number of tiles per floor is similar to the algorithm described above:

1. Find the floor area.
2. Divide the floor area by the area of ​​one tile.

Common Questions

• How to calculate the number of tiles for a bathroom if they are laid diagonally on the floor or wall? In this case, the counting algorithm is no different.
