Harvia Onni Onyx Duo infrared sauna

Onni Onyx Duo brings immediate infrared warmth to shared relaxation. The heat is available quickly and directly, without heating the entire room volume first. Each seating position includes a full-spectrum radiator behind the back, complemented by carbon panels at the sides and lower body. This configuration creates steady and evenly distributed warmth that surrounds the body comfortably. The dark exterior in black waxed hemlock gives the cabin a confident, modern appearance. Red cedar inside adds warmth and natural depth. The glass front keeps the design visually open. Operation is managed via a large touch screen. Adjustable chromotherapy lighting and integrated Bluetooth audio allow individual customization. The structured construction with integrated components enables installation within a few hours and supports long-term daily use. Onni Onyx Duo is shared infrared comfort — balanced in warmth, composed in design, and made for consistent everyday wellbeing.
