The HUUM HIVE FLOW™ Wood-Burning Sauna Stove & Rock Bundle pairs HUUM’s newest eco-efficient heater with 10 boxes of olivine diabase stones (≈ 330 lb total) to create deep, velvety löyly in any traditional sauna. Engineered for rooms 282 – 635 ft³, the compact body (34.8 H × 20.7 W × 23.1 D in) slips easily into a corner or center layout while meeting tight 6-inch side clearances. A patent-pending flow-through firebox drives pre-heated air up through the stones for higher burn temperatures, lower emissions, and a mesmerizing flame view. Chimney kit not included; complete the install with any UL/CSA class-A 4.5-inch insulated flue.

For eco-conscious sauna lovers, the HIVE Flow stands out. It emits just 346 mg/m³ of CO—less than one-third of what similar stoves produce—and its particulate emissions are only 25 mg/m³, the lowest in its class, ensuring a cleaner, more memorable sauna experience.
