Experience unmatched heat performance and true Nordic craftsmanship with the HUUM HIVE Flow LS Wood-Burning Sauna Stove — engineered for sauna purists who demand efficiency, aesthetic beauty, and an authentic löyly experience.
The Flow LS model features an innovative firebox extension, allowing you to conveniently load firewood from outside the sauna room. Beyond convenience, HUUM’s patent-pending combustion system ensures that up to 75% of the fire’s heat is transferred directly into the sauna, minimizing energy loss through the chimney and maximizing every log you burn.
With support for sauna rooms from 282 to 635 cubic feet, a massive 330-lb stone capacity, and beautifully rounded olivine stones, the HIVE Flow LS delivers gentle, long-lasting steam and rich heat saturation — the hallmark of an elite wood-burning sauna system.
Designed and crafted in Estonia, the HIVE Flow LS is built for both sustainability and longevity. Its efficient burn, clean emissions profile, and architectural design make it one of the most environmentally conscious sauna stoves available today.
If you want a premium wood-burning stove that elevates the atmosphere, efficiency, and performance of your sauna, the HIVE Flow LS is the gold standard.
