How Much Tile Do I Need for a Shower?
A shower is the hardest tile surface to estimate fast because it is several surfaces at once: three walls, a floor or pan, and usually a niche — each with its own cuts and waterproofing.
Measure surface by surface
Do each wall as height × width, add the shower floor or pan, and add the niche walls and shelf. Subtract the door or curb opening. Because showers are cut-heavy, use a higher waste factor — 15% or more. The tile calculator keeps walls and floor as separate line items.
Do not forget waterproofing
A shower needs a waterproofing membrane and often backer board behind the tile — real material and labor that belong on the quote, not a surprise on install day. See the estimating checklist for the full line-item list.
FAQ
How much waste should I add for a shower?
At least 15%, more with mosaics or a decorative pattern, because showers have many cuts around the niche, curb and fixtures.
Should waterproofing be in the tile quote?
Yes — membrane, backer board and corners are required in a wet area and should be separate line items, not absorbed into the tile price.
