JONAS is Celsium’s luxury outdoor sauna collection, designed as a freestanding architectural structure for private residences and hospitality projects. Available in five models — Mini, Classic, Grand, Classic Lounge and Grand Lounge — each JONAS sauna is built from premium natural materials with modern Scandinavian design, and can be customized to bring indoor comfort to an outdoor setting.
