Designed for two, the Duo Sauna delivers an intimate, traditional sauna experience in a sleek, space-saving footprint. Its efficient layout and clean lines make it ideal for small patios, decks, or urban outdoor spaces—without sacrificing heat performance or comfort.

After your sauna session, refresh in the Alaskan All-In-One Cold Plunge. Engineered for high performance and ease of use, this plunge tub delivers the full benefits of contrast therapy—supporting muscle recovery, circulation, and deep relaxation.

The Power of Contrast Therapy

Maximize recovery and relaxation with the Fire & Ice routine:
✔️ Boost circulation & cardiovascular health by alternating between hot and cold
✔️ Enhance muscle recovery after workouts or intense physical activity
✔️ Reduce stress & improve sleep by activating the parasympathetic nervous system
✔️ Support mental resilience through controlled cold exposure

Built to Last with Thermowood

Crafted from premium hemlock thermowood, the Duo Sauna & Alaskan are engineered for durability and longevity. Thermal modification enhances the wood’s stability, insulating properties, and resistance to rot and fungi—ensuring your sauna and cold plunge withstand the elements with minimal maintenance.

Easy DIY Assembly

Our hassle-free assembly means no sawing or cutting—just pre-cut, interlocking panels that you can build in a few hours with basic DIY skills.
