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.
Tile contractors may create blueprints or lay out tiles on a dry surface to prepare decorative mosaics or patterns. Installers use electric or mechanical tools to cut tiles to go around toilet bowls, pipes and other fixtures. Tiles contractors lay tiles on a flat, clean and level surface. Tile contractors will sometimes install new drywall, tile backer board or another material to a wall, ceiling or floor to be tiled. Concrete floors and other uneven surfaces may need to be leveled with mortar.
