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.

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.

To ensure an even and unbending surface to lay tiles on, you’ll typically need to put a subfloor under a tile floor. Fiber cement backboards are the most common choice, but using plywood is also possible. Don’t neglect this step, or you could risk water damage and grout or tiles prematurely cracking or crumbling, especially in an area with high foot traffic. 

The number of boxes of tile you need depends entirely on the amount of tile in each box or case. Different manufacturers package their tiles differently, and boxes contain different amounts of tile depending on the size, shape, and material. Often, the amount of area that a case will cover is listed in the product description. To calculate the number of boxes you need, take the total square feet of the space and divide it by the number of square feet the box will cover.
