How To Install Floor Tiles In A Bathroom?

Bathrooms are often the most visited places in any building, mostly to answer to a call of nature. Without a doubt, it would be a nightmare for a house without a bathroom. Being a highly trafficked area, you need to make it even look amazing for people who will be visiting it. The method highlighted in this guide should be best applicable for installing the tiles in a home bathroom. Once you get all the materials ready, it should be easy to handle the rest of the work.

What you will need?

  • Level
  • Tape measure
  • Grout
  • Tiles
  • Cleaning cloths
  • Buckets
  • Knee pads
  • Rubber gloves
  • Hammer
  • Goggles
  • Sponge
  • Tile saw


1. Taking Measurements

The first step would be getting the measurements of the whole bathroom floor or the part you need to remodel. Take out your tape measure and record the measurements of each side of the bathroom. Measuring the floor helps with determining just how many tiles, grout, mortar and backing board you will need for the whole process. The worst can be buying too much or too less to finish the project. It is often just an estimation, so buying more would be better than less. With more, you can always replace a broken tile rather than miss one.

2. Preparing to install the tiles

Here is a YouTube video on additional tips for preparing the surface:

  • The next step is to prepare the surface for installing the tiles. You will need to mix the thin-set mortar in the mixing bucket to the right consistency as directed by the manufacturer.
  • With your mixture of mortar ready, start to apply from a reference line in the middle of the bathroom. Spread the mortar using the trowel over a considerable area. You might alternate this with installing tiles until you are done.
  • Using the notched side of the trowel, you can now comb the mortar into one direction to ensure there is a uniform application.
  • Proceed to remove the excess mortar on the surface and throw it back in the bucket.

3. Installing the floor tiles

  • Take your tile and place it on the reference lines with the newly placed mortar in place. To experience the best results, make sure to press and twist the tile when installing it. Such activities help with setting the tile into the mortar correctly.
  • Place the tile spacers at the edge of that first tile. It is from the first tile that you can continue to lay the other tiles correctly with just the right amount of space between them.
  • Make sure that you at least had enough tile spacers to use for the whole bathroom. Continue to lay the tiles in the same way along your reference lines and adding the spacers with each tile laid.
  • Once you have completed with the laying of the tiles at the section, you need to make sure that the tiles are on the same level. By using a rubber mallet and a carpenter’s level, you can now level the tiles to be the same before the mortar dries up.
  • You can now remove the excess mortar on the sides of the tiles by using a damp sponge.
  • Now that you get the idea on how the lay the tiles, proceed to with applying the thin-set mortar from the mixing bucket. Apply to various sections and lay the tiles. You can always make adjustments where needed to ensure that the tiles are aligned in a straight line. This is why you have to keep using the tile spaces to achieve a uniform spacing.

4. Cutting the Tiles

Check out this video for more information on cutting and layering of the floor tiles:

It is possible that at some point you will need to cut the tiles for them to fit. In the bathroom scenario, this would be important to accommodate the bathroom fixtures and near the walls and cabinets.

  • Depending on the type of cut you need, the saw used will be different. For the holes, you will need to use the circular saws. They are made to handle such type of applications. For the straight pieces, using a tile saw would be appropriate at this point.
  • Once you have made the cuts, simply snap off the pieces using the tile nippers.
  • The newly cut tiles will have a rough edge, so some smoothening is needed to make them easily align with the others or bathroom fixtures. Using a file, proceed to smoothen the rough edges of the newly cut tiles. With the tile ready, you can now lay it in position just as you did with the others.

5. Grouting the Tiles

  • At this point, you do not need the tile spacers; so you can remove them.
  • Mix the grout by following the stated instructions from the manufacturer. It is always important to maintain the water to mix ratio for better consistency.
  • Apply the grout mixture into the tile joints for all the tiles and remove the excess ground using the damp sponge.
  • You can give the grout about 20 minutes to dry or as stated by the manufacturer. Proceed to wipe the grout lines with a damp sponge in a circular motion. You can still use a grout haze remover to deal with stubborn grout.
  • Apply the sealant to the grout after a couple of days when the grout is dried up. You will also want to avoid using the bathroom for days until everything has dried up nicely.


By now, you must have learned something about installing the floor tiles in a bathroom. If you follow the steps correctly, it should not be a problem at all. You will always end up with a nice looking bathroom that you have always wanted. The best part is that you can do all this on a budget rather than hiring someone to handle the remodeling.
