Rooted in wabi-sabi restraint, this bathroom pairs a cast-concrete soaking tub with earthen lime plaster walls that reveal straw and expressive cracks. A terracotta-plaster accent wall and ceiling warm the palette, balanced by cool blue-gray stone pavers set in black pebbles. Rice-paper lanterns and a slim skylight wash the space with soft, directional light. A charred timber bench and a fractured mirror embrace imperfection, giving the minimal layout soulful texture.
