Grout and caulk are commonly used together, especially in bathrooms. Grout goes between the tiles and keeps them sturdy and in place on the walls or floor. Caulk goes in corners or where two different materials meet (like where the bathtub meets the tile) to create a waterproof seal. However, they are not interchangeable—you shouldn't use caulk to adhere tile and shouldn’t use mortar if you need a waterproof seal.

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.

Natural stone floors, especially pebble-style tiling, are one of the least slippery options for a shower floor. Natural stone has a texture to reduce slickness, and pebble-shaped tiles add more visual and textural contrast while reducing slippage. Vinyl tiles are also designed with anti-slip texture for added safety. If you have a slippery tile, be sure to add a grippy shower mat to reduce the risk of falls.

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.
