Duo Sauna x Denali Cold Plunge

Designed for modern outdoor living, the Duo Sauna offers a space-efficient footprint without sacrificing comfort. Ideal for small backyards or couples seeking a cozy retreat, this 2-person sauna combines thoughtful design with high-quality materials. Paired with the Denali All-in-One Cold Plunge, it creates the ultimate contrast therapy setup—bringing the rejuvenating benefits of hot and cold to your own backyard.

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 is built to endure the elements. Thermal modification enhances the wood’s durability, insulation, and resistance to rot and fungi—ensuring long-lasting performance with minimal upkeep.

Easy DIY Assembly
Our saunas are designed for straightforward assembly—no sawing or cutting needed. Pre-cut, interlocking panels make it possible to set up the Duo in just a few hours with basic tools and DIY skills.
