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 these round sauna stones in their heaters. When water is poured on the stones, the round shape helps the water to penetrate to the inner stones and disperses the water more uniformly.  This allows the water to evaporate gradually, providing a more uniform steam, instead of vaporizing quickly from the top layer.  These sauna stones are made from an Olivine diabase known for its durability and high thermal capacity.

HUUM heaters are designed to have highly visible sauna stones.  When adding stones to the heater you should carefully add smaller and larger stones to fill the heater evenly without noticeable gaps, using slightly smaller stones near the top to provide a dense top layer that help enhance heat accumulation.
