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

Genuine Harvia AC3020 sauna stones are olivie diabase split-face stones selected according to traditional Finnish sauna standards. These authentic sauna stones deliver consistent, soft heat and create the genuine sauna atmosphere that Harvia is known for worldwide.

Why Split-Face Stones Matter for Electric Heaters

Split-face sauna stones are the only correct choice for electric heaters and woodburning stoves. The angular, fractured surface of these olivie diabase stones stores substantial heat while allowing water to evaporate efficiently across the wide fracture surfaces. This design creates the optimal steam and heat distribution that defines a quality sauna experience.

The angular shape enables loose placement of stones, which is critical for electric heater performance. Proper air circulation between stones and heating elements extends the lifespan of your electric heating elements while ensuring efficient heat transfer into your sauna room.
