Can I tile over an already tiled entryway?

Ceramic tile? No, I don't think there are too many tile installers that would recommend tiling over existing tile. The only exception I can think of is if it was actually too low and you needed to cover over it with a leveler anyway, then maybe it'd be okay?

I have done it with no problem. First you need to make sure that the tile is REALLY stuck down properly. Any loose tile will ruin anything that you put over it.

Hi Debbie,

What is causing your disatifaction?

If it is in good condition, but not your taste, it could be painted. I wouldn't put tile over tile, personally.
