Harvia AC3055 Elite Pro Heavy-Duty Sauna Heater Stones, Split-Face, 10-15cm

Engineered for commercial and high-use residential saunas, the Harvia AC3055 Elite Pro Heavy-Duty Sauna Heater Stones deliver exceptional heat retention, durability, and steam production. Crafted from premium grey olivine diabase and heat-treated at approximately 1000°C, these professional-grade sauna stones are designed to withstand repeated heating and cooling cycles while maintaining outstanding performance.

Their split-face design provides a large surface area that efficiently vaporizes water, producing abundant, soft steam for a more enjoyable sauna experience. The stones are easy to stack, allowing excellent airflow through the heater for optimal heat distribution and consistent performance. Naturally occurring micropores help release moisture gradually, creating smooth, comfortable steam with every use.

Compatible with electric sauna heaters or as a surface layer for wood-burning sauna stoves, the Harvia AC3055 stones are an ideal choice for anyone seeking reliable performance and long-lasting durability.
