The HUUM HIVE Flow 9.8kW Wood-Burning Sauna Stove Package with Thru-Ceiling Chimney Kit comes complete with the HIVE Flow 9.8kW sauna stove, protective bed, thru-ceiling chimney kit, and sauna stones. This stove package brings the timeless tradition of wood-burning heat in sauna rooms from 282 to 635 cubic feet (CF).

Inspired by Nordic design principles, this compact model efficiently channels warmth throughout the space while maintaining the clean, timeless aesthetic HUUM is known for.

Built from durable steel with a 5 mm top and 3 mm sides, the HIVE Flow ensures even heat distribution and long-lasting durability. Despite its smaller size, it accommodates up to 330 lb (150 kg) of stones—and an optional stone cage allows for an additional 77–88 lb (35–40 kg), extending the heat retention period for comfortable, consistent steam.

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 reflects HUUM’s commitment to thoughtful engineering and modern craftsmanship.
