The last part of my bathroom remodel project was a new tile floor. I ripped up the most recent layer of tile, but didn’t want to disturb the original 1950’s tile floor. The bathroom was built around the floor, so it was easier just to tile over it.
A couple of things to consider if you want to tile over an existing tile floor are:
- The old tiles all need to be secured to the floor. If they are starting to pop up, you either need to reattach them or pull them all up.
- The old tiles need to be smooth without corners sticking up or high points. If you try to tile over an uneven surface with new ceramic tile, they could break.
- The overall height of the floor needs to be able to accommodate another layer of tile (think transitions in the doorway and any moldings in the room).
Luckily for me, all of these things were in my favor.
