Description

The ThermaSol Solaris Sauna Cabin brings together modern design, solar-powered performance, and outdoor wellness in a distinctive off-grid sauna. Recognized by TIME as one of the Best Inventions of 2025, the Solaris is designed to deliver a traditional sauna experience without requiring a conventional power connection, offering greater flexibility for outdoor installations.

Its UV-resistant Tile Oak cladding creates a contemporary European aesthetic, complemented by brushed alder benches and backrests. Solar panels integrated into the roof and exterior wall work with a connected battery system to power sauna sessions, while solar-tinted glass, an expansive window, and customizable RGB LED lighting create a comfortable and personalized atmosphere.

Available in Small and Medium sizes, the Solaris accommodates up to three or five people, respectively. Fully assembled for delivery, it offers a distinctive wellness retreat for gardens, patios, and other suitable outdoor spaces.

Backed by a 1-year manufacturer warranty, the Solaris combines thoughtful design with an innovative approach to outdoor sauna living.

Delivery & Shipping

Shipping costs are calculated based on the delivery location. The Solaris is delivered fully assembled via flatbed trailer.

Customers are typically notified approximately two weeks before the scheduled delivery to allow time for preparation. Due to the sauna's size and weight, a forklift or crane is required for placement. Manual offloading is not recommended. Please confirm unloading equipment, site access, and delivery arrangements before scheduling.

The installation site should have a firm, level surface with suitable drainage, such as concrete, decking, pavers, or compacted gravel. The delivery path must be clear and accessible for the equipment used to position the sauna.

Although the Solaris is designed for off-grid operation, confirm the electrical and installation requirements for the specific model with the manufacturer before delivery. Also verify whether any licensed electrical work is required for the heater, controls, or solar system.
