ThermaSol Solaris Sauna Cabin – Fully Assembled Solar-Powered Outdoor Sauna (2–5 Person)

Product Description

The ThermaSol Solaris Sauna Cabin revolutionizes outdoor wellness with the world’s first fully solar-powered, off-grid sauna system. Recognized by TIME as one of the Best Inventions of 2025, Solaris operates entirely without a traditional electrical connection — giving you total freedom to enjoy authentic sauna therapy wherever sunlight is available.

Designed for eco-conscious homeowners, luxury spa environments, remote properties, and off-grid living, this innovative sauna blends modern European architecture with sustainable engineering. Both interior and exterior surfaces are finished in UV-resistant Tile Oak cladding, creating a sleek, contemporary aesthetic that integrates seamlessly into natural landscapes.

Integrated solar panels mounted on the roof and exterior wall collect energy efficiently, requiring only one full day of sunlight for a complete charge. A mobile app monitoring system allows users to track power levels and performance in real time for total control and reliability.

Inside, a full-length solar-tinted glass door and panoramic window framed in alder wood invite natural light while maintaining privacy. Brushed alder benches provide ergonomic comfort while the Harvia KIP heater produces gentle, restorative heat — entirely powered by solar energy. Recessed RGB LED lighting enhances the atmosphere with customizable color therapy for a fully immersive wellness experience.

The Solaris delivers unmatched independence, sustainability, and performance — redefining what luxury outdoor sauna ownership can be.
