Bathroom Hexagon Floor Tile in Columbine
This bathroom floor replacement in a Columbine home used large-format 12-inch hexagon tile in a matte gray finish. Large hexagons present a different layout challenge than rectangular tile: the pattern has no obvious starting axis, so establishing the center point of the room and working outward in all six directions simultaneously is essential to keeping the pattern symmetrical. We dry-laid the full floor before setting a single tile to confirm the layout and identify where cut tiles would fall at the walls.
The existing subfloor was a wood-frame construction over a crawl space, common in Columbine homes of this era. We installed a layer of 1/4-inch cement backer board over the existing plywood to provide a stable, non-organic surface for the tile mortar. Unsanded grout in a light gray tone was used to keep the joints subtle against the tile face.
