How does delivery work?

This sauna arrives fully assembled and ships on a large, secure pallet via LTL freight. Because of its size and weight, you will need to arrange a crane or forklift to move the sauna from the curb to its final location on your property.

Our team will contact you before delivery to review all logistics, answer questions, and ensure you’re fully prepared for a smooth drop-off.

The carrier will reach out to schedule a convenient delivery window, and tracking updates will be provided throughout the process. Protective packaging is included to help ensure your sauna arrives in perfect condition.

What are the electrical requirements?

Thermasol saunas require a 220–240V hardwired connection with a dedicated breaker. Dedicated 120V is also required for accessories such as lighting and controls.  We recommend confirming the exact amperage and wire size with your electrician based on the heater model.

How is the sauna built?

The ThermaSol Solaris Sauna Cabin is built using an insulated outdoor-ready structure with UV-resistant Tile Oak exterior finishes and brushed alder benches inside. Solar-tinted panoramic glass panels provide natural light and privacy, while integrated solar panels and battery storage allow fully off-grid operation without an external power connection. The sauna arrives fully assembled for streamlined installation.

What are the dimensions?

Small Exterior Dimensions: 86”L x 60”W x 97”H

Medium Exterior Dimensions: 86”L x 86”W x 97”H

What is the warranty?

Every Thermasol sauna is protected by a 1-year warranty covering the cabin structure and non-electrical components.

Heater warranties are provided directly by the manufacturer and vary by brand:

Harvia: 2 years residential warranty

HUUM: Limited 3-year residential warranty (excluding heating elements)

Description

ThermaSol Solaris Outdoor Sauna Cabin

The ThermaSol Solaris Outdoor Sauna Cabin is a groundbreaking architectural masterpiece engineered to bring sustainable, eco-friendly luxury to any destination on earth. As the world's first fully solar-powered, completely off-grid sauna system, this visionary cabin operates seamlessly using integrated high-capacity solar panels and dedicated battery storage banks—requiring absolutely no electrical grid hookups or complex utility wiring. Available in two distinct footprints—a space-optimized Small configuration for 2 to 3 bathers or an expanded Medium social layout for 4 to 5 bathers—the Solaris serves as a striking geometric focal point for lakeside retreats, mountain properties, private backyards, or premium estate patios.

Crafted in Finland to premium European standards, its unique design blends a contemporary, UV-resistant Tile Oak clad exterior with a stunning interior lined in Tile Oak surfaces and ultra-smooth, brushed Alder wood benches. This innovative material palette radiates a deep, organic warmth and high-end tactile comfort, offering a grounding, low-maintenance outdoor sanctuary that perfectly elevates any luxury residential landscape.

The defining visual highlight of the Solaris series is its expansive solar-tinted panoramic glass wall paired with a matching standard glass door facade. This specialized thermal glazing floods the cabin with soft, natural light and dissolves visual boundaries to connect you deeply with your surroundings, while strictly preserving absolute personal privacy and blocking intense solar heat from the outside. To support deep physical recovery and mental decompression, the cabin features an integrated LED ambient lighting system. This calming illumination network is managed alongside the thermal environment via the intuitive Xenio CX170 digital control panel, bathing the rich wood and tile textures in customizable waves of soothing light tailored for twilight or daytime meditation.

Beneath its polished Scandinavian styling, the Solaris is packed with elite engineering optimized for off-grid thermal efficiency. Driving the environment is a compact, high-performance Harvia Delta 3.6kW electric heater, optimized for low-energy consumption while generating fast, gentle, and deeply therapeutic steam. Shipped fully pre-assembled from the factory via flatbed for a fast, turnkey installation, this connected, solar-powered oasis delivers an uncompromising backyard retreat built for eco-conscious, lifetime year-round rejuvenation.
