Checkerboard Foyer Floor in Northbrook
This foyer floor in Northbrook uses large-format gray and white marble tiles set on a 45-degree diagonal to create a classic checkerboard pattern. The diagonal set makes the entry feel more expansive than the square footage alone would suggest — a practical design choice in a foyer that transitions directly to a staircase and adjacent hallway.
Diagonal tile installation increases the cut count significantly because every wall perimeter tile requires a 45-degree cut. We snapped diagonal layout lines from the center of the foyer and dry-laid the first two rows before mixing any adhesive to confirm the pattern would be centered and that the cut tiles at each wall would be roughly equal in size. A polymer-modified thinset was used for the large-format marble to ensure full coverage and prevent hollow spots under the tile.
