A pared-back bath pairs a rectangular concrete sink with a rough-cut stone ledge beneath a frameless mirror and wall-mounted black faucet. Smooth lime-plaster walls in warm off-white echo the seamless floor, while a slim clerestory window washes the space with diffuse daylight. Minimal accessories and an exposed matte-black trap keep lines honest, letting texture—cool gray concrete, rugged stone, and soft plaster—define the minimalist look.
