Hand-carved from stone, the soaking tub anchors this Wabi-Sabi bathroom, set on smooth river rocks and lit through shoji-style wood-and-paper screens. Lime-plaster walls with simple niches and a draped towel add quiet texture. A reclaimed wood vanity and wall-mounted matte-black taps keep the lines honest. Warm taupe, honeyed wood, and weathered stone shape a calm, imperfectly beautiful retreat.
