Product information updated 2026-10-02
Aito AK-57 – larger heat-storing sauna heater, designed for more spacious saunas. Due to its larger stone capacity, it ensures an even more stable and longer-lasting heat and steam effect.
This heater is ideally suited for those who value long sauna sessions and a constant temperature. One firing is enough for the whole evening, and the heat lasts for a long time afterward.
