A sunken ofuro lined in honed limestone anchors this Zen bathroom, flanked by dark-stained vertical wood slats and brushed bronze fixtures, from rain shower to low-profile tub filler. Shoji screens open to a moss garden and raked gravel. A skylight and concealed LED coves bathe surfaces in soft light, while a niche and folded towels preserve symmetry and calm, embodying Japanese restraint and material honesty.
