Porcelain tiles are highly recommended for the bathroom or kitchen because it is not covered by enamel, its finish is usually polished or polished of great durability and with very low water absorption.
As it has very low water absorption, it will not allow mushrooms to flourish. In addition, being harder and more resistant, they can be installed between palms, without setting, which also prevents the appearance of fungi.

Bathroom flooring – 10 Steps – How to lay floor tile
Laying floor tile – Step 1: Calculate the quantity of material
Estimate the quantity of material that will be needed in the project, for this it is necessary to consider that each box has written on the package the m2 that it covers or the number of tiles that it brings.
To cube the walls it is necessary to add the linear meters and multiply the result by the height of the room. And this result is subtracted from the measurements of doors and windows.
It is always advisable to carry an additional box of material for future contingencies. Now, if we were talking about a large installation, it would be considered a 10% loss.
Laying floor tile – Step 2: Prepare the floor surface
For the bathroom floor, you need to apply a layer of waterproof primer before tiling. Then, run silicone sealer along all the corners. You can also use waterproof bands. Finally, apply another coat of waterproofing membrane.
For drainage purpose, keep the floor on a slope.
Use chalk to divide the room into quadrants, you will start tiling from the center point.
Tip: You can lay dry the tiles to see how it looks, and to minimize the small cuts.
Laying floor tile – Step 3: Prepare the wall surface
For walls it is also recommended that the walls be concrete or stuccoed.
The surface must be washed with water. It doesn’t matter if it gets wet, as this will prevent the mixture from dehydration, this is called “saturated surface”.
In the case of partition walls, it is recommended to install textured fibrocement first, as it will have the rough surface necessary for the adhesive and the tiles to have a better grip.
Note: For bathroom wall, remember to waterproof the wall first.
Laying floor tile – Step 4: Prepare the adhesive
- Pour the powdered adhesive in a bucket and add the little water, stir with a flat until you have a homogeneous and thick paste, like toothpaste.
- The powdered adhesives are predosed, this means that it comes with all the necessary additives for a correct adhesive paste, you only have to prepare with water. The one chosen for this material is EF for stones and porcelain, marble, granite and stone coatings, which are the heaviest and thickest. Another advantage of this type of adhesive is that it avoids the loss and unnecessary stockpiling of material.
Laying floor tile – Step 5: Lay the tiles on the floor
- Starting with the center point of the quadrants, then follow the line.
- Tiles gluing is done with a notched trowel, as their teeth leave adhesive strips necessary for a better grip, and the spaces without adhesive are left with air that will be sucked once the tile is seated, this also helps the adhesive to dry better.
- Use a notched trowel to spread the adhesive over a small area only (like 1m2) to work on. This prevents the adhesive from drying.
- Place the tiles on the adhesive, then use a rubber mallet to gently tap on.
- Between each run of tiles leave the plastic spacers as you go.
Note: Leave a small gap between the floor tile and the wall if you tile the wall later.
Laying floor tile – Step 6: Straight cuts on tiles
If planned correctly, you can do all the cuts for the rows end and corners before beginning.
For a small job you can use a snap cutter, otherwise, a power wet saw is an option for you.
Laying floor tile – Step 7: Curved cuts in the tiles
- To install tiles in the floor and wall it is necessary to make some curved or circular cuts to make coincide with the flush of the WC and the water exits. These cuts are made with the angle grinder and a diamond cut-off wheel. The cut on the tile must be 3 mm larger than the diameter of the drain or water outlet.
- To check the levels, it can be done with a lead and hose with water or with a laser level that rectifies slope and collapse.
- To fix a horizontal line, for example to the 50 cm, and to rectify with a huincha the distance with the floor, measuring in several points of the line. Where the greatest unevenness is to put the horizontal line of the laser to 60 cm, which is the height of the palmette. The idea is to cut pieces of the tiles to correct the unevenness, and not add small pieces that visually will not look good.
Laying floor tile – Step 8: Install the tiles on the walls
- This is similar to lay tiles on the floor, except that you will lay row by row at a time
- Use a suitable notched trowel to spread out the adhesive ( 8mm for tiles smaller than 300x300mm; 10mm or 12mm trowel for bigger tiles)
Laying floor tile – Step 9: Grouting
Grouting is the last part and if done nicely, it will make your finishing like a pro.
- Mix the grout to a thick consistent paste
- Apply it into the joints using a trowel, make sure it completely fills in the joints
- Using a sponge to wipe the excess grout diagonally as you do
