Harvia AC3020 Olivie Diabase Sauna Stones - 10-15cm Split-Face x3

Harvia AC3020 Olivie Diabase Sauna Stones - Set of 3

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

Genuine Harvia AC3020 sauna stones deliver authentic Finnish sauna heat with superior thermal performance. These olivie diabase stones are hand-selected using traditional methods to ensure optimal heat retention and steam production for your sauna sessions.

Split-Face Design for Maximum Heat Distribution

The split-face construction of these sauna stones creates wide, irregular surfaces that maximize water evaporation and steam generation. This angular design allows proper air circulation between stones and heating elements, extending the lifespan of your electric sauna heater while providing consistent, soft heat throughout your sauna room.

High-Heat Capacity Olivie Diabase Material

Harvia uses olivie diabase stone for its exceptional durability and heat storage properties. These volcanic stones withstand repeated heating cycles without cracking or deteriorating, making them the correct choice for both electric heaters and woodburning stoves. The 4-6 inch (10-15 cm) size range ensures proper stone placement and optimal heat circulation.

Why Split-Face Stones Matter

Split-face sauna stones are essential for proper sauna heater function. Their irregular surfaces and angular shape allow loose stone placement, creating air gaps that enable heat transfer from heating elements to your sauna room. This airflow prevents overheating of electrical components and ensures even heat distribution. Smooth stones lack these critical characteristics and can reduce heater efficiency and longevity.

Good air circulation in the stone compartment protects your heating elements and maintains consistent sauna temperature. The wide fracture surfaces of Harvia's split-face stones evaporate water efficiently, producing the soft, enveloping steam that defines an authentic Finnish sauna experience.
