Yes, tiling a bathroom is a great way to boost your home's value, especially if you are replacing old or dated flooring. Adding a new tile floor can deliver a return on investment (ROI) of around 56.4%, with some projects offering up to 100% ROI. Buyers appreciate new tile because it provides a modern look and is known for being durable, water-resistant, low-maintenance, and easy to clean. For the best results and highest return, consider hiring a professional, as tiling mistakes can be very noticeable and detract from the value.

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.

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.

It’s not necessarily normal for tiles to lift, although it’s one of the common issues people may have with their tile flooring. Tiles correctly installed by pros with expansion joints should not lift over time. However, if the installation was done poorly, you might see tiles tenting or lifting as the house settles. This is more common in high-moisture areas with extreme temperatures.
