Notes
- Thinset coverage is set by trowel size, not by room size — a 6" tile needs a 1/4" × 1/4" square-notch, so a 50 lb bag covers about 95 ft².
- Add 15% instead of 10% for a diagonal layout, a room with many jogs, or if the tile has a pattern that has to line up.
- Grout is figured at 0.125" joints and 0.3125" tile thickness. Wider joints raise it quickly.
Tiles, and then some
The floor is 352 ft². Buying exactly that much is how people end up back at the store: cuts at the walls, the odd broken tile and a spare box for future repairs mean you order 387.2 ft² — 10% over.
At 6″ square that works out to 1,549 tiles.
Thinset depends on the tile, not the room
This is where rule-of-thumb estimates go wrong. A bigger tile needs a bigger notched trowel, and a bigger notch puts down more mortar per square foot. For 6″ tile you want a 1/4" × 1/4" square-notch, which is why the bag count here is 5 rather than whatever a generic calculator returns.
Before you order
Measure the room at more than one point. Rooms are rarely square, and the widest measurement is the one that decides how many tiles the last row needs.
