Harvia AC3020 Olivine Diabase Sauna Stones - Professional Grade

Only available with the purchase of a Harvia sauna heater or stove.

Genuine Harvia AC3020 sauna stones are selected according to old traditions and convey an authentic sauna atmosphere. These olivine diabase stones provide consistent, soft heat distribution essential for an optimal sauna experience.

Split-Face Design for Maximum Performance

Split-face sauna stones are the only correct stone type for electric heaters and woodburning stoves. The fractured surface allows water to evaporate efficiently while storing substantial heat. Angular split-face stones enable loose placement, which is critical for electric heaters as it allows heat to circulate freely between the hot stones and heating elements. This proper air circulation extends the lifespan of electric heating elements significantly.

Why Olivine Diabase Stones

Olivine diabase is specifically chosen for its exceptional heat retention properties and durability under repeated heating cycles. The natural composition of these stones withstands thermal stress while maintaining structural integrity, ensuring years of reliable sauna performance. The split-face texture maximizes surface area for efficient steam generation when water contacts the heated stones.

Proper stone placement using these angular stones maintains optimal airflow through your heater, protecting heating elements and ensuring even heat distribution throughout your sauna room.
