The Harvia AC3000 Split-Face Sauna Stones (5–10 cm) are the official, factory-recommended stones for all Harvia electric and wood-burning sauna heaters. Sourced and selected following Harvia’s long-standing stone traditions, these angular olivine diabase stones deliver authentic, soft, and abundant steam while maximizing heater performance and longevity.
Their split-face structure allows water to spread and evaporate efficiently across a broad fracture surface, producing deeper, richer löyly. The angular shape also enables looser stacking, improving airflow between stones—an essential factor for protecting electric heating elements and ensuring fast, even heating.
These stones are sold only with the purchase of a Harvia heater or stove, ensuring the correct pairing between heater design and stone performance.
