Bathrooms are naturally moisture-rich environments, so choose a durable, water-resistant tile for your tub surround. Porcelain and ceramic are two popular options that are also quite affordable. Glass is another good option that’s also low-maintenance—you just need a glass cleaner like you would use on the bathroom mirror. Natural stone tile is porous, but it’s still a viable option if you choose it in a glazed version.

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.

Glass tile is one of the easiest materials to maintain. It is both stain and water-resistant, making it easy to clean and incredibly durable. This also makes it resistant to mold and mildew. However, make sure it’s kept clean, otherwise, your grout might start to degrade. Glass is liable to scratch, so ensure you’re using non-abrasive materials and products, like soft sponges and wipes.

The lifespan of bathroom tile can be 50 years or more, depending on proper installation and regular maintenance. A well-done tile job, whether it's a new installation or a retiling project, can last for many decades. To lengthen the life of your tile, it's best to have it installed by a professional and to perform regular maintenance. This includes routine cleaning, resealing, and regrouting as needed. With proper care, you can expect your tile to last 10 years or more before needing major repairs or retiling, especially in high-traffic areas where tiles can wear out more quickly.
