Kupu Sauna: Where Scandinavian Design Meets Japanese Ritual

A masterwork in spatial design and sensory detail, the Kupu Sauna from Maruni marries Scandinavian restraint with Japanese craftsmanship. Designed by Wataru Kumano, its half-dome form optimizes heat flow while echoing the quiet elegance of hinoki wood. The fragrance, the grain, the joinery, each element speaks to a philosophy of presence and precision. Compact yet immersive, it invites a deeper ritual of restoration. Whether installed as a singular form or expanded into a full-length retreat, Kupu transforms daily bathing into a meditative design experience.
