12" x 12" River Stone Glass Mosaic · SKU 4010-99-22507
Measure the length × width of the area you’re tiling — whether it’s a floor, wall, shower, or backsplash.
We’ll automatically calculate approximately how many tiles and boxes you’ll need based on this tile size, including a recommended allowance for cuts and installation waste.
By default we add a small number of extra tiles on top of what the room needs. Prefer a percentage instead? Switch below.
We add this many whole tiles on top of the minimum needed for your measurements (corners, cuts, a little breakage).
Your estimate
We round up to full cartons. If the tiles already in those cartons cover your extras for cuts and waste, we won’t bump you up another box unless you need it.
