The HUUM HIVE Flow Mini Wood-Burning Sauna Stove brings exceptional heat performance to smaller sauna rooms without compromising style or quality. 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 Mini ensures even heat distribution and long-lasting durability. Despite its smaller size, it accommodates up to 231 lb (105 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 Mini reflects HUUM’s commitment to thoughtful engineering and modern craftsmanship.
