Thinset mortar is the best adhesive for ceramic tiles on concrete. It is easy to work with and has a slower dry time than mastic or epoxy mortars. This longer dry time gives the installer more time to adjust tiles, which is especially useful for DIYers who may not have tile installation experience. It can also be built up to help level any depressions or gaps in the concrete subfloor.

To make a bathroom look bigger, choose light-colored, medium- to large-format tiles. Light colors such as white, cream, or light gray make a space feel more open, while dark colors, busy patterns, and small tiles can make a bathroom feel smaller. It may seem counterintuitive, but small tiles can shrink a room visually due to the increased number of grout lines. Using medium- to large-format tiles creates a more seamless look. For the best effect, pair your light-colored tiles with a matching or similarly colored grout. This minimizes the grid-like pattern and gives the floor and walls a more continuous, uninterrupted appearance, helping the room feel significantly larger.

Yes. You can tile over tile if the old tile is in good shape, but this will also create a thicker floor. As a result, you may have to remove and readjust baseboards and other room trimmings and potentially even raise door heights to work with the higher floors. In most projects, it’s best to remove the old tile before installing a new tile floor.

Using caulk is one of the simplest and most recommended methods to finish glass tile edges. It creates an elegant seam between the glass tile and the adjacent area, along with a waterproof seal. With this method, you want to use a caulk color that matches the grout and, along with the grout, compliments the tile. Make sure the caulk line is smooth and even. Alternatively, you can use a bullnose or tile trimming to edge, however, that will also require caulk to seal.
