Product Overview
Olivine diabase is one of the most durable and heat-stable stone types for sauna use. The split-face cut exposes more raw stone surface than rounded stones, which means more contact area for water — producing a denser, more enveloping steam when you ladle water for löyly.
Stack these 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 — rinse stones before first use. Replace any cracked or crumbling stones per 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.
