Vassa Finnish Barrel Sauna with WiFi Heater

Few outdoor luxury investments command a space quite like the Vassa Finnish Barrel Sauna — an 86.61" interior, 6-person barrel sauna that stands as the most expansive model in the Finnish Sauna Builders lineup. Engineered for families, entertainers, and serious wellness enthusiasts, the Vassa channels every inch of its generous 94.49" exterior length into sauna volume, delivering the rare combination of a truly elite Finnish sauna experience with the capacity to host up to six guests simultaneously. Backed by the Harvia Spirit 8KW WiFi Heater and crafted from chemical-free treated Northern European Spruce, this is the outdoor barrel sauna for those who refuse to compromise on scale.

The Vassa's defining advantage over every other model in the series is its interior length: at 86.61 inches, it offers 24 more interior inches than the Turku and more than double the Tampere — meaning full-length reclining on the 2-tier benches is genuinely possible for multiple guests at once. Whether installed as the centerpiece of a resort-caliber backyard or as a permanent wellness feature for an active family, the Vassa rewards the investment with years of elite-grade therapeutic heat. Choose from four sophisticated exterior stain finishes — Natural, Walnut, Teak, or Larch — to ensure seamless integration with any premium outdoor environment.
