The HUUM HIVE Flow Mini LS 8.5kW Wood-Burning Sauna Stove Package with Thru-Ceiling Chimney Kit comes complete with the HIVE Flow LS 8.5kW sauna stove, thru-ceiling chimney kit, protective bed, and sauna stones. This stove package brings the timeless tradition of wood-burning heat in sauna rooms from 212 to 494 cubic feet.

The HIVE Flow Mini LS model with a Firebox Extension allows the fire to be conveniently fed from an adjacent room, keeping the sauna area tidy and comfortable. Its innovative furnace construction maximizes wood efficiency and heat output, reducing waste and extending warmth. With a 231 lb (105 kg) stone capacity and the option to add an extra 77–88 lb (35–40 kg) in a stone cage, the HIVE Flow Mini LS provides gentle, long-lasting steam that enhances every sauna session.

The stove’s rounded form and glass furnace door create a natural focal point, offering both visual appeal and functional efficiency. Designed and manufactured in Estonia, the HIVE Flow Mini reflects HUUM’s commitment to thoughtful engineering and modern craftsmanship.
