The Duo Outdoor Sauna is a compact, minimalist two-person retreat designed for couples and small spaces—perfect for transforming urban backyards, patios, or rooftop gardens into a personal wellness oasis.

Crafted from premium heat-treated hemlock thermowood, this sauna is engineered for durability, superior insulation, and resistance to rot and fungi, ensuring it withstands outdoor elements with minimal maintenance. Rooted in Scandinavian tradition, the Duo heats quickly and retains warmth efficiently, offering authentic dry or steam heat sessions that promote relaxation, improve circulation, and support muscle recovery.

Easy DIY assembly with pre-cut, interlocking panels means you can build your sauna in just a few hours, even with basic skills.

Customize with multiple Harvia or Homecraft heater options (6kW to 9kW), plus add-ons like luxury bucket sets, thermometers, and aromatherapy diffusers to create your ideal at-home retreat.
