Harvia AC3000

Sauna Heater Stones, Split Face, 5-10cm

Enhance your sauna’s performance with Harvia AC3000 Sauna Stones, sized 5–10 cm and crafted for optimal heat retention and steam quality. These genuine Harvia stones are compatible with both electric and wood-burning Harvia heaters, ensuring an authentic, efficient, and soothing sauna experience.

Available exclusively with the purchase of a Harvia sauna heater or stove.

Each stone is naturally formed, meaning variations in shape, size, and texture are expected—this is part of what creates their exceptional thermal performance. To achieve the best fit and airflow within your heater, we recommend adding an extra box of stones, allowing you to hand-select the ideal pieces for heat distribution and longevity. (Additional freight charges may apply.)

Harvia’s traditional stone-selection process ensures stones that deliver soft, consistent heat and excellent steam production. Their split-face structure maximizes surface area for efficient evaporation, superior heat storage, and enhanced airflow between heating elements—especially crucial for electric heaters to extend element life and maintain peak performance.
