Description

The Harvia AC3040 sauna heater stones are crafted from fine-grained vulcanite volcanic rock, naturally dark grey and turning black when wet. Each stone’s split-face design provides excellent heat storage, supporting efficient steam generation when water is poured over heated surfaces.

These stones are engineered to withstand fluctuating temperatures, making them suitable for electric sauna heaters or as the surface layer on wood-burning sauna stoves. The split-face texture allows for proper stacking and air circulation, ensuring consistent heat distribution and rapid vaporization.

Each stone is naturally unique in shape and size, allowing for a tailored fit and visual variety in sauna interiors. The AC3040 stones are clean, durable, and ready to use without additional treatment.
