Split-Face Olivine Diabase Stones for Compatible Sauna Heaters
The Harvia AC3000 split-face olivine diabase sauna stones offer heat retention and steam performance for compatible electric and wood-burning sauna heaters. The split-face surface exposes more stone area than rounded stones for water evaporation and löyly. Each box contains 45 lbs (approximately 20 kg) of 5–10 cm stones. Use only with heaters specifying this stone size.
Product Overview
Olivine diabase is a durable, heat-stable stone used in sauna heaters. The split-face cut exposes raw stone surfaces for contact with water when you ladle water for löyly.
Stack stones loosely following your heater manufacturer’s guidelines to maintain proper airflow around the heating elements. Many heaters require more than one box. Check your heater’s stone capacity before ordering.
Note: Natural stone varies in shape, color, and texture. Stone dust may be present from shipping, so rinse stones before first use. Replace cracked or crumbling stones according to your heater manufacturer’s recommendations. Harvia recommends replacing sauna stones every 1–2 years, depending on frequency of use.

What people like
Pros
- High Heat Retention: The dense olivine diabase material stores and releases heat effectively, ensuring a consistent and authentic sauna experience.
- Improved Air Circulation: The angular, split-face shape allows for loose stacking, which creates channels for air to flow through the heater, protecting the elements.
- Efficient Steam Production: The broad, rough surface area of the stones allows water to evaporate quickly, resulting in rich, soft steam.
- Durable Material: These stones are designed to withstand repeated high-heat cycles without crumbling or breaking down prematurely.
Cons
- Delivery Issues: Some customers have reported significant problems and delays with the shipping and delivery process.
- High Shipping Costs: Freight charges can be expensive, particularly if the stones are ordered without a sauna heater or stove.
- Limited Availability: Some retailers restrict the purchase of these stones, requiring them to be bought alongside a heater unit.
- Weight Challenges: The heavy 44-45 lb packaging can make individual handling and transport difficult for some users.
