HUUM HIVE Flow Wood Burning Sauna Stove- Complete Package Options

Industry-Leading Heating Efficiency – The HUUM HIVE Flow directs up to 75% of heat from the firewood directly into your sauna instead of losing it through the chimney, creating faster heat-up times, lower wood consumption, and longer-lasting warmth.

Soft, Luxurious Steam Experience – With an impressive 330 lb stone capacity, the HIVE Flow produces exceptionally gentle, even heat and rich traditional löyly that continues radiating warmth long after the fire burns down.

Eco-Friendly Wood-Burning Technology – Engineered with HUUM’s innovative low-emission combustion system, the HIVE Flow is one of the most environmentally sustainable wood-burning sauna stoves available, meeting strict European environmental standards.

Luxury Scandinavian Craftsmanship – Designed and handcrafted in Estonia, the HIVE Flow blends minimalist Nordic aesthetics with cutting-edge sauna engineering, creating a true statement centerpiece for luxury indoor and outdoor sauna spaces.

Mesmerizing Fireplace Ambiance – The large tempered glass furnace door allows you to enjoy the calming glow and natural crackle of real wood fire while relaxing in your sauna.

Flexible Installation Options – Dual chimney connection compatibility supports both through-wall and through-ceiling chimney installations, offering greater flexibility for custom sauna builds.
