How this calculator works
Sheet coverage is (width × height) ÷ 144 square feet. We divide your area — with waste — by sheet coverage and round up. Mosaic waste is lower than plank patterns because you can pull individual chips off the mesh to fill gaps, but curves and drains push it back up.
Watch out for nominal vs actual sheet size: a sheet sold as 12×12 often measures 11.7 inches, which is about 5% less coverage. Use the actual dimensions from the spec sheet when precision matters.
Frequently asked questions
How much waste for mosaic tile?
10–12% is typical. Shower floors with a center drain can need 15% because every sheet touching the drain gets cut. Straight accent strips can go as low as 8%.
Do mosaics need special thinset?
Use a white, polymer-modified thinset so the color does not shadow through glass or light stone. Comb it with a small V-notch trowel and flatten the ridges — they telegraph through thin sheets.
Can mosaic sheets go on a shower floor?
Yes, and they are the best choice: the dense grout lines provide grip and the small chips follow the slope to the drain. Look for sheets rated for floor use.
