No, you don’t need to remove the old grout before installing new tile over existing tile. In fact, the old grout helps fill in gaps between tiles, creating a more even surface for the new layer. However, it's important to ensure that the grout is clean, solid, and free of cracks or crumbling areas. Damaged grout should be repaired or replaced before proceeding. Cleaning the surface thoroughly and filling any low spots will help the new adhesive bond properly and ensure a smooth, stable installation.

When choosing tiles for a shower floor, avoid highly porous tile materials, like those with a water absorption rating over 7%. Don’t use non-vitreous tiles, or tiles fired at low temperatures, because they will absorb more water. If you use a highly porous tile in the shower, the tiles can wear down faster, meaning they’ll need to be replaced much sooner.

Tile removal costs about $2 to $7 per square foot unless you do it yourself. When you hire a pro, tile installation costs $5 to $45 per square foot. Costs vary widely, but they depend on the tile material (custom-made stone tiles cost significantly more than plain ceramic tile), location, and tile size.

If you want your ceramic tiles to be evenly spaced and installation to take less time, spacers are a crucial part of the installation process.
