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.

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 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.

Glass tiles are among the most difficult to install. This is because their transparency makes the adhesive visible, and any imperfections on the opposite side are also likely to be visible. Glass tiles also must be handled carefully during installation, as they are prone to scratching. For these reasons, glass tiles often require professional installation to get the most out of their beauty and unique look.
