Shower Tile Calculator

To get an accurate tile estimate for your shower, start by measuring the height and width of each wall or floor section you plan to tile. Once you have those dimensions, enter them into the shower tile calculator along with your tile size and waste percentage. The calculator will automatically factor in the measurements and provide the total number of tiles needed — saving you time and reducing the risk of miscalculations.

Yes, it’s recommended to include a waste factor of 10–15% to account for tile cuts, pattern matching, and accidental breakage. Showers often have niches, corners, and irregular shapes that lead to more cuts than flat walls. Our calculator automatically adds this buffer unless you choose to adjust it.

Popular shower tile sizes include 3x6 inches (subway tiles), 4x4 inches, and larger formats like 12x24 inches. Smaller mosaic tiles are often used on floors for better grip. The best tile size depends on your design, the shape of your shower, and how much grout visibility you want. Our calculator works with any size, just enter your tile dimensions.

By default, the calculator does not account for grout lines since they vary in width. However, if you want a more precise estimate, you can slightly reduce the tile size input to account for the grout spacing. Most users find that including a waste percentage already compensates for this minor difference.

Yes, for showers and other wet areas, it's important to use waterproof or water-resistant grout. Epoxy grout is highly recommended because it's durable, non-porous, and resists water, stains, and mold. If you're using cement-based grout, make sure to seal it properly after installation. Choosing the right grout helps protect your shower from long-term moisture damage.
