Harvia Onni Onyx One infrared sauna

Onni Onyx One is designed for effortless daily infrared use. The heat is available almost instantly, without the need to pre-heat the entire cabin. This makes sessions flexible and easy to integrate into everyday routines. A full-spectrum radiator behind the back provides intensive and deep infrared warmth, supported by carbon panels at the sides, under the calves and under the feet. The combination ensures even heat distribution across the body while keeping the surrounding air at a comfortable level. The black waxed hemlock exterior gives the cabin a clear and modern presence. Inside, red cedar adds warmth and a natural scent that enhances the experience over time. The open glass front keeps the design visually balanced and light. A large touch screen allows straight forward adjustment of temperature and lighting. Chromotherapy lighting and integrated Bluetooth audio support a personalized session. The cabin is built from structured elements with integrated components, enabling assembly within a few hours and reliable use for years. Onni Onyx One is a personal infrared space — defined in design, precise in heat delivery, and built for dependable daily use.
