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.

As long as you follow the instructions on your peel-and-stick tile packaging, it should not damage your walls. A possible instance when you may accidentally damage your walls is if you install tiles improperly using additional adhesives that aren’t recommended.

Also, you can damage your walls if you’re not careful when removing tile. For example, you could accidentally make holes in the drywall with a paint scraper if you don’t heat the adhesive long enough before trying to pry it off.

On average, tiling a bathroom involves about 12 hours of labor, usually spread over two to three days to accommodate prep work and curing times. A professional tiler can often complete the installation in 6 to 8 hours, whereas a DIYer might take 10 to 16 hours. The total project time is influenced by factors like the bathroom layout, tile type, and necessary prep work, such as removing old tile. The process includes specific timelines for different areas; for example, tiling a floor takes about six hours, while a shower area can take six to ten hours. It is essential to allow for adequate curing time—typically 24 hours each—for the mortar, grout, and caulk, which is why the project extends over several days.

Replacing tile flooring can take a few days for a pro, but larger rooms will need more time. It takes eight to 12 hours for a tiling pro to remove old grout and tiles across 100 square feet. Then, it will take about four hours to prep the subfloor for tiles and another eight to 10 hours for a pro to install new tiles. Your tiling project may take up to a week, depending on the size of the room.
