This bathtub area was inspired by the Japanese idea of shinrin yoku, or forest bathing. The soaking tub was positioned beneath a large window letting in forest views. Hexagonal marble tiles create a snappy geometric pattern on the floor. A small room used to hold this primary bathroom's toilet. Reconfiguring the space—and taking out that small space—allowed designer Alexandra Lauren to add a large window and wet room, and let in pretty views and lots of natural light.
