HUUM HIVE 12kW Electric Sauna Heater
Product Overview
The HUUM HIVE 12kW Electric Sauna Heater is a high-performance floor-standing heater designed for sauna rooms from 12–25 m³ (430–880 cu. ft.). Featuring a massive 250 kg (550 lb) stone capacity and precision-crafted stainless steel construction, it delivers soft, long-lasting heat that closely replicates a traditional wood-fired sauna.
