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.

Yes, cracked tiles allow water to seep through the substrate or subfloor, leading to mold and mildew growth. It can also cause severe structural damage. At the very least, water damage can cause your tile to lift from the substrate, meaning one cracked tile can lead to several cracked tiles. It’s a good idea to waterproof tile in areas with direct water exposure or lots of moisture.

Figure out how much tile you need by measuring the backsplash area. Measure the height and length in feet and multiply to get the square footage. Don’t make adjustments for outlets or small cutouts but subtract the square footage for windows or other large obstructions from the total. To account for waste, get 10% more than your calculation.

You can technically install tile over tile, but we don’t suggest it. Installing tile over any surface that isn’t a completely flat and prepared subfloor will result in a shoddy overall job, uneven flooring, tiles that don’t adhere, extra weight, gaps, cracks, and room for moisture and dirt to enter. For the best results, only install new tile on a flat, sanded surface like subflooring or concrete that is prepared for tile.

If you have asbestos tile and would rather tile over it than remove it, or if your existing tile is completely flat and bonded tightly to the floor, you may be able to tile over existing tile. But experts recommend thinking twice before you do.
