Transform your sauna into a true Nordic wellness retreat with the HUUM HIVE Flow Mini LS Wood Sauna Stove — an ultra-efficient, luxury wood-burning sauna heater engineered in Estonia for exceptional heat retention, cleaner combustion, and soft, long-lasting steam. Designed for sauna rooms from 212–494 cubic feet, the HIVE Flow Mini LS combines authentic wood-fired sauna tradition with modern Scandinavian engineering and eco-conscious performance.

Unlike traditional wood sauna stoves that lose much of their heat through the chimney, the patent-pending HUUM furnace construction directs up to 75% of generated heat directly into your sauna for superior efficiency, lower wood consumption, and a more sustainable sauna experience.

The LS (firebox extension) model allows you to load firewood from outside the sauna room, helping keep your sauna clean while preserving interior heat and creating a more luxurious sauna experience. Its large stone capacity delivers exceptionally gentle, consistent löyly steam that continues long after the fire has burned down.
