Inspired by the contemporary aesthetics of our Aire sauna, the Onnen sauna features an expansive glass wall for an uninterrupted view of nature. Its smaller footprint makes it one of our most efficient designs.

The teardrop-shaped wall-mounted HUUM ‘Drop’ stove smoothly balances the structure's straight lines, and the two-tier floating benches give the Onnen a clean, minimalistic feel. The lower bench's narrower profile is perfect for resting your feet while relaxing on the top bench or for enjoying a lower-intensity session with gentler heat.

During the daytime, the glass wall also allows for a sauna bathed in natural light, making the Onnen a tranquil space for reading and relaxing. The overhanging single-pitched roof provides a sheltered area with warm downlighting for hanging towels and changing, and the side entrance enhances a sense of privacy.

The black-stained cedar external cladding allows the Onnen to sit back in the landscape and blend into the shadows at dawn and dusk.

The Onnen comfortably seats up to four people. Its small footprint makes it ideal for residential gardens and space-saving projects. As with all our electric saunas, the Onnen's stove can be controlled via a mobile app and set to your desired temperature from anywhere, at any time.
