# Floor tile

> Tiling floors: layout, underlayment, setting and grout. Ask with your Sheet attached: homeowners who’ve done it and verified pros answer, and anyone can read it.

## Before you ask

The room size, the tile size, what’s under it, and the joist span if it’s a wood floor.

- **Attach your Sheet** so people see your sizes and the math.
- **Your town is enough.** Never your address; check photos for house numbers and plates.
- **Is it safe?** A safety question here goes to pros verified in tile, unless you pick another trade. Only they can call it safe or unsafe.

## Tile a floor

8′ × 5′ bathroom: 19 tiles, 2 bags of thinset, 1 bag of grout and the backer board, sized to your tile.

What people get wrong:

- **Grouting the change of plane.** Grout at walls and the tub cracks as the house moves.
- **Too small a trowel.** Big tile over thin ridges leaves hollow spots that crack when stepped on.
- **Forgetting the new floor height.** The floor rises about 1″.
