Diagonal tile layout basics
A diagonal or diamond layout rotates the tile grid 45° relative to the walls. The visual effect makes rooms appear larger and hides slightly-out-of-square walls. The trade-off is more waste — every tile that meets a wall must be cut at an angle.
When to use diagonal layout
- Rooms that aren't perfectly square (the angled grid disguises it).
- When you want to visually expand a small space.
- Entryways and foyers where a standard grid looks too plain.
Waste considerations
Budget 15% waste minimum. Unlike straight layouts where half-tiles can be reused at the opposite wall, diagonal cuts produce triangular off-cuts that rarely fit elsewhere. In rooms with many corners or alcoves, increase to 20%.
