HUUM Sauna Stones

For use in HUUM Drop & HUUM Mini Hive Heaters only

HUUM round sauna stones with a diameter of 2-4 in / 5–10 cm.

HUUM recommends round sauna stones in their heaters. The round shape ensures the water being poured on reaches down to the inner stones to help the water evaporate gradually as opposed to vaporizing from the top layer.  These sauna stones are Olivine diabase known for their durability and high thermal capacity.

HUUM heaters are built where the sauna stones are highly visible in their design, which will require you to add in smaller and larger stones to fill the heater evenly without noticeable gaps.  It’s suggested when stacking that the top layer is dense, with slightly smaller stones to help with enhancing the accumulation of heat.
