A compact one-person infrared cabin for everyday relaxation at home
The HARVIA Onni Sienna One is an elegant infrared cabin designed for one person, offering a convenient way to enjoy soothing infrared heat therapy in the comfort of your home. Its compact dimensions make it easy to integrate into various living spaces, while the modern design with a large glass front creates a spacious and contemporary appearance.
The cabin features a mahogany exterior finish combined with a mahogany and Hemlock interior, creating a warm and inviting atmosphere. Carefully selected materials and high-quality craftsmanship ensure both durability and a premium look.
The HARVIA Onni Sienna One utilizes a combined infrared heating system. A full-spectrum infrared heater positioned behind the user provides intensive heat exposure, while carbon panel heaters integrated into the side walls, under the bench, and in the floor ensure even heat distribution throughout the cabin. This combination delivers a comfortable and relaxing infrared experience from the very first minutes of use.
Convenient operation is provided through a modern 7-inch touchscreen control panel, allowing users to adjust temperature, session duration, and save personal settings. Integrated RGBW chromotherapy lighting and a Bluetooth audio system further enhance the relaxation experience, enabling users to create a personalized wellness environment.
