Is tiling over tiles a good idea?

So, in short, you can tile over tile as long as you're working on a fairly sound surface. The surface of the existing tile should be free of mold and mildew, completely level (including grout), and without any warping or strangely-placed tiles that might otherwise interfere with a smooth new layer.

Can tile be laid over tile?

Tile can be installed directly over a concrete slab or over a wood subfloor with an added layer of backer board. Tile can even be installed over an existing tile floor. When laying tile over tile, it is best to use a modified thin-set. This is a bonding mortar with either a latex or polymer additive.

Can you put peel and stick tiles over tiles?

Tile Over Existing Tile As long as you prepare your existing surface well, you can place most peel-and-stick tiles over existing surfaces. Do keep in mind that some peel-and-stick tiles will only adhere well when the grout lines are filled in to be flush with the existing tile.
