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.

Yes, you can tile over existing tiles in a bathroom, but it is not always recommended. For this method to be successful, the original tile surface must be clean, flat, and free of damage such as cracks, unevenness, mold, or mildew. While tiling over existing tiles can save time and money, there are potential drawbacks. The new adhesive may not bond properly, and the process adds extra weight to the wall or floor. Additionally, the increased height of the surface could interfere with door clearances. For the best and most durable results, removing the old tiles before installing new ones is generally the better option.

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.

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.
