Yes, it’s possible to cut tile without a wet saw; instead, you can use an angle grinder, a glass cutter, a snap cutter, tile nippers, or a rotary tool with a tile-cutting blade. A manual tile cutter or snap cutter works well for the larger tiles that wet saws are typically used for, while smaller projects might just require nippers or a glass cutting wheel. If you’re working with large quantities of tile, however, power tools are best.

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.

You can attach tiles to a wall using thin-set mortar. You’ll also need a notched trowel to create grooves within the adhesive so it flattens completely when pressed in and securely holds the wall tiles. Finally, you’ll need grout to smooth the gaps between the tiles and, ideally, a grout sealer to prevent mold. While it sounds simple enough, proper planning and execution are crucial, so carefully review the steps in this guide or hire a pro tile installer to complete this project.

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.
