An unapologetically industrial bathroom pairs raw materials with crisp function: a cast-concrete soaking tub sits beside a corner shower with ribbed acrylic panels, opposite a wall-mounted porcelain sink on pipe legs. Olive green paneled walls meet diamond-plate aluminum wainscoting, while exposed galvanized ducts and bold red valves define the architecture. A dark epoxy floor with steel drainage grates and a large skylight plus cage lights create a rugged, workshop-like atmosphere, with graphic contrast from safety-red accents.
