how to tile a bathroom floor


As we head into the holiday season, it’s common to want to start making home improvements inside your home. There are a few key areas in your home that bring the most value when they look nice. The first is your front yard. The second area to consider renovating is the kitchen. Finally, you want to think about redoing your bathrooms. If your bathroom is updated for the most part, aside from the floors, you’re in luck. This project isn’t too complex, and we’re confident you can do it with a little bit of guidance. As with most projects, it’s good to have an extra set of hands close by to help. We’re going to show you how to tile a bathroom floor. 

Before you start doing anything, you need to think about your materials. Tile floors are an excellent asset for any home. Tile is a great material to use in rooms like your kitchen and bathroom for several reasons. These floors are naturally resistant to smells, stains, moisture, and they’re incredibly simple to clean. So, you know you’ve made the right decision. Let’s take a look at what you need to get the job done right. 


What You Need

To get this project going, you need a few things. Some may be more obvious than others: 

  • Tile
  • Cement backer board
  • Pry bar
  • Hammer
  • Chalk line
  • Tape measure
  • tile spacers
  • mastic
  • tile nippers
  • grout
  • wet saw
  • grout float
  • sponges
  • grooved trowels


This material list is pretty basic, so you may want more tools based on your skill level. Now, let’s jump into how to tile a bathroom floor: 


        1.) Whatever you’re working on top of, whether that’s existing flooring or subfloor, you need to lay cement backer board.

        2.) Remove all trim and thresholds. 

        3.) Stack the backer board and tile together to see how high the new flooring will be, and cut the door jams to fit the new tile. 

        4.) Remove your toilet. 

        5.) Using the trowel, spread some mastic on the backer board and lay it down. Attach it to the subfloor with screws. Leave about an eighth of an inch between the boards. 

        6.) Cut the board with a circular saw for the most accurate cuts. 

        7.) Tape over joints with joint tape and spread mastic over the tape. 

        8.) Using a grooved trowel, spread mastic on the board.

        9.) Press the first tile down into the mastic with a slight twisting motion. Tip: always start in the center of the room.

       10.) Repeat step nine, and use the spacers to maintain even spacing. 

       11.) Cut tiles that will go along the wall with the wet saw. 

       12.) Once all tiles are set, spread grout with rubber float until spaces are full. 

       13.) After the grout has dried some, wipe off any excess grout with a moist sponge. 

       14.) Finally, after the grout dries, clean off the floor with a moist towel. Buff it until clean. 

       15.) Allow the floor to dry for a week before applying any sealant. Note: you only need sealant for natural stone tile to prevent stains and damage.
