How Do You Install Ceramic Tile Over Vinyl Flooring?
It’s usually not a good idea to install ceramic tile directly over a vinyl floor, because vinyl is not solid enough to ensure an immobile base for the tile. In most cases, you’ll want to install a layer of cement board over the vinyl and then tile over that. However, you can go directly over vinyl in certain circumstances–if it’s a small space in a dry room (not a bathroom), and the vinyl is thick and solid and doesn’t have any “give” to the surface.

Run the sander forward and back in overlapping rows, moving on when the gloss or shine is gone from the floor. Thoroughly vacuum the dust. Stretch your chalk snap line across the floor, from the middle of one wall to the middle of the wall across from it, dividing the room in two.
