Off-grid and roaring after every shift

I'm ski patrol at altitude and my cabin sauna runs on wood by necessity and by choice. The Kuru 20 has the firebox for serious heat and shrugs off Sierra cold. I lined the wall behind it with the Stainless Steel Lining from here and the pairing is bombproof. Sauna Co. shipped both together and the rep actually understood high-altitude draft, which most don't.

Big firebox, big heat

This thing eats logs and pays you back with a furnace of a sauna. Our 7-person room is hot through and through in no time. The freight arrived palletized and intact, right on schedule.

Real fire, real heat

The water hisses off these stones into a steam you can lean into. The big door makes the flames part of the experience. Communication was prompt and genuinely helpful.

Built for abuse

Heavy steel, clean welds, and it laughs at the cold. I run it hard and it doesn't care. Delivery beat the estimate and the packaging was overkill in the best way.

The cabin's beating heart

From the first burn it became the reason we drive up every weekend. Solid as a vault. The rep's chimney advice was spot on and the heater landed without a scratch.

Powerful, give it a proper chimney

Heats like nothing I've owned, but a 20kW-class burner needs a serious flue. Support walked me through the venting before I bought so there were no surprises mid-project.

Worth every log

Tending the fire is part of what I look forward to now. Clean burn, long heat retention, gorgeous flames. Sauna Co. kept me in the loop the entire way.
