Overview
The best sauna experiences don't happen in a gym. They happen at the lake's edge, in the backyard after a long training week, at a cabin in January when the temperature has dropped and the wood is already cut. The Hearth brings that experience with you — a four-person, wood-fired portable sauna designed in Duluth, Minnesota, that reaches 200°F in 30 minutes and sets up in under 10.
This is authentic sauna culture. Not infrared approximation, not a heated room — wood fire, thermal stones, steam finish, and the kind of deep, enveloping heat that actually changes how your body feels afterward. The high-ceiling vertical wall design seats four adults comfortably without the cramped quarters that compromise most portable sauna formats, and the heavy-duty heat-resistant fabric with integrated rain cover and chimney port performs in rain, snow, and winter conditions without modification.
At 42 lbs and packing down to 54" x 10", the Hearth fits in a trunk or truck bed and goes where the weekend takes you. It's the sauna for people who don't stay in one place — and who refuse to leave their wellness practice behind when they leave.

Why You'll Love It
The case for wood-fired over infrared isn't aesthetic — it's physiological. Traditional high-heat sauna bathing with steam finish produces a fundamentally different experience than infrared at lower temperatures: a deeper sweat, greater cardiovascular response, and the kind of full-body release that's been documented across centuries of Nordic sauna culture rather than decades of consumer wellness marketing. The Hearth is built to deliver that, not approximate it.
The pop-up hub design solves the setup problem that keeps most people from committing to outdoor sauna culture. At under 10 minutes from bag to heat-ready, the Hearth is practical enough for a Tuesday evening after training, not just a planned weekend event. The vertical wall and elevated ceiling design means the interior feels like a sauna, not a camping tent — four adults sit with room to move, and the benching keeps you elevated in the heat zone where temperatures are highest and the therapeutic value is greatest.
Built for the lower 48, the Elite Experience package adds a dimension no other portable sauna offers: white-glove on-site delivery, professional setup, and a guided first steam session with Venik treatment — making the Hearth a legitimate option for corporate wellness retreats, luxury hospitality activations, and homeowners who want a professionally curated introduction to traditional sauna culture rather than a self-guided first attempt.

The Hearth is the heat half of the equation. Pair it with the Crestline Cold Plunge Tub for a complete contrast therapy setup — alternating between 200°F wood-fired heat and cold immersion is one of the most researched and time-tested recovery protocols available.
