Small size. Bold heat. The HUUM HIVE Mini 9 kW Heater proves that tradition doesn’t have to be oversized to be unforgettable. It delivers the kind of rolling, lingering steam usually reserved for much larger heaters, wrapping sauna rooms up to 530 cu ft in heat that feels both powerful and refined.

This package doesn’t ask you to piece things together. It gives you everything in one elegant stroke: the stainless steel HIVE Mini heater, intuitive UKU control (Wi-Fi optional), and carefully chosen olivine stones that turn fire into softness. Crafted in Estonia, this package is a modern heirloom for anyone who craves a true European sauna experience, scaled perfectly for more intimate spaces.
