Harvia AC3020 Sauna Stones — 20 kg (10–15 cm)

Ensure a premium sauna experience with Harvia AC3020 sauna stones — high-quality olivine-diabase rocks crafted according to traditional Finnish sauna standards. These robust stones are designed for large electric and wood-burning sauna heaters, delivering excellent heat retention and steam performance.

The 10–15 cm size range is ideal for creating a solid foundation in your heater, promoting efficient air circulation and stable heat distribution. Their split-face structure stores significant thermal energy and enhances steam formation when water is poured over the hot stones, resulting in a soft, satisfying sauna steam every time.

Whether you’re outfitting a new sauna or refreshing your stones, Harvia sauna stones help you unlock deep heat, consistent steam, and long-lasting performance from your heater.

For standard wood-burning and electric stove models Etna 12 / 12SN / 18 and Harvia BC60 / PC70 / PC70E / BC80 / PC90 / PC90E, 80 kg of sauna stones are required for proper operation.

For more powerful wood-burning stove models Cozy 12 O-TW and Stoveman 13R-LS, 100 kg of sauna stones are required for proper operation.

Please carefully check the exact quantity of stones ordered — the amount you order is the amount that will be delivered.
