This industrial mudroom combines glossy white subway-tile walls with a gray epoxy concrete floor marked by a yellow-edged trench drain. Slate-blue powder-coated lockers with expanded-metal doors anchor the corner, opposite a light wood bench on black steel legs. Exposed galvanized pipes, rusted beams, and chain-hook rails underscore utility, while linear LEDs and a skylight with blue accent glow lift the cool, durable palette.
