Ask a Tradesman. Best Answer. You can tile over the current tiles, and as another tradesman has stated please check the tiles are sound and not loose as this would cause problems later. Should they be loose, remove these and level the hole/gap to match the existing tiles, either with bonding/tile adhesive.
This same tile also needs to be approved for a wet location. So when it's installed, 95 percent of the back side of the tile needs to be in contact with the thinset (tile concrete). Often, thinset is installed with a notched trowel, and not all tiles â such as many mosaic tiles â can reach 95 percent coverage.
