The master bath is a simple rectangle. “Like the kitchen, I designed it so that no stuff was laying around,” Erik said. The surfaces are natural and subdued; a simple palette of tones, colors, and materials unifies the space. Travertine marble was used on the floors, shower, and countertop. The closet and cabinetry are maple. Erik designed the light fixture himself because, he says, “there was nothing I could find that fit the scale of the room.” He used cold-rolled steel with exposed wires to give it an industrial feel.
