How Many Tiles for a 5x7 Bathroom Floor? (2026 Guide)
A 5×7 ft (35 sq ft) bathroom floor takes about 35 net 12×12 in tiles — buy 39 with a 10% waste buffer. Large 12×24 in tiles run about 18 net (buy 20); 8×8 in tiles run about 79 net (buy 87).
Tile count at a glance for a 5×7 bathroom
Five feet by seven feet works out to 60 × 84 in — exactly 35 sq ft of floor. The tile count is simply 35 divided by the area of one tile, plus about 10% extra for cuts and breakage.
| Tile size | Area per tile | Net for 35 sq ft | Buy (+10% waste) |
|---|---|---|---|
| 12×12 in | 1.0 sq ft | 35 | 39 |
| 12×24 in | 2.0 sq ft | 18 | 20 |
| 8×8 in | 0.44 sq ft | 79 | 87 |
| 6×6 in | 0.25 sq ft | 140 | 154 |
The net column rounds up to a whole tile (you can't buy 17.5 of them); the buy column adds the 10% buffer and rounds up again.
Worked example: 12×12 tiles on 35 sq ft
A 12×12 in tile covers exactly 1 sq ft, so a clean 60 × 84 in rectangle takes five tiles across and seven deep — 35 whole tiles, zero cuts in theory. Real bathrooms rarely stay that tidy: the toilet flange, the vanity toe-kick and the door casing each force a cut or two, and tiles chip when you drop them.
So add the standard 10% buffer: 35 × 1.10 = 38.5, which rounds up to 39 tiles to buy. That leaves about four spares — enough for the odd cut piece plus a broken tile or a miscut. Order them all at once, because dye lots shift between batches. Check your final floor plan with the tile calculator before you place the order.
Bathroom floor details that change the count
The same divide-and-buffer math scales to any bath: see how many tiles a 3×5 bathroom floor needs, or if you're pricing in square feet rather than pieces, how many tiles per square foot lays out the per-tile areas. Tiling the stall in the same job? How many tiles a 4×6 shower takes follows the same method.
FAQ
How many 12×12 tiles do I need for a 5×7 bathroom floor?
A 5×7 ft floor is 35 sq ft, and each 12×12 in tile covers exactly 1 sq ft, so you need about 35 net tiles. Add 10% for cuts around the toilet and vanity plus a breakage buffer: 35 × 1.10 = 38.5, rounded up to 39 tiles.
Should I subtract the tub or shower from the floor count?
Yes — tile only the floor you walk on. A built-in tub or shower base sits on the subfloor with no tile beneath it, so leave its footprint out and measure the exposed net floor first. Covering under a tub just wastes tile and money.
Do 12×24 large-format tiles roughly halve the tile count?
Roughly, yes. A 12×24 in tile covers 2 sq ft, so the 35 sq ft floor takes about 17.5 — rounded up to 18 net tiles instead of 35 for 12×12, and you buy 20 with waste. Fewer pieces also means fewer grout lines and a faster install.
