How to Tile a Bathroom Floor

What You'll Need: 

- tile supplies

- tile saw

How It's Done: 

- The beginning to end project steps: Measure floor, prepare underlayment, attach underlayment, cut tile for dry fit, apply thin-set mortar, place tiles down and use tile spacers, allow mortar to dry overnight, apply grout, wipe away excess grout, and finally, if necessary, apply grout sealer.

 - Use a drill with a square driver bit to attach backerboard screws to sub-floor with applied thin-set. Screws must rest flat once secured. (We used 1/4 “ Hardieboard.)

- Before adhering to the subfloor, lay out sheets of mosaic tile for a dry-fit to determine the pattern. Sheet tiles can be cut with a utility knife. Once the pattern is set, use a tape measure to center the design.

- Make necessary cuts with wet saw. To make small cuts, use a tile nipper.

- Mix thinset to a creamy consistency by adding water incrementally.

- Use a 1/4” square notched trowel to apply thinset.

- Place sheets of cut mosaic tile to complete floor layout. Make sure tile is placed evenly and use spacers to hold in position.

- When tile is all in place, allow mortar to dry for 24 hours before applying grout.

- Once mortar is dry, remove spacers, apply grout with a grout float. Completely fill spaces between tiles. To see my 15-second video applying charcoal-colored grout to the mosaic tile floor, click here.

- Final Step: After applying grout, use a damp sponge to wipe away excess grout. The tile floor will be ready to walk on in 24 hours, however may take longer to fully cure.
