Surrealist fantasy meets function in this narrow bath, where coral plaster walls lead to a deep blue end wall and an oval mirror of a sunset surf. A freestanding Carrara marble tub sits beneath a droplet glass chandelier and a rippling, water-like ceiling. Black basalt flooring is strewn with iridescent starfish and pearls, while stepped stainless-steel shelves float along the wall, mixing reflective textures and dreamlike illusions for an underwater aura.
