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.

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.

The best trowel for penny tile is a 3/16-inch-by-5/32-inch V-notch trowel. Because of the small size of the penny tile, you want a trowel with small notches that can lay a thin layer of mortar on the surface you’re tiling. If the notches are too wide, you risk applying too thick of a layer of mortar, and it can squeeze out between the penny tiles.
