Rounded Olivine Diabase Stones for Compatible Sauna Heaters
Fill your compatible sauna heater with Harvia R-991 rounded olivine diabase stones, natural, chemical-free stones sized 5–10 cm (2–4 in.) and packaged in a 33 lb (15 kg) box. Their rounded shape allows water to flow through the stone bed when you ladle water for löyly. Use with electric or wood-burning sauna heaters that specify this stone type and size.
Product Overview
Olivine diabase is a dense, heat-resistant stone used in sauna heaters. Harvia’s rounded stones sit in your heater’s stone compartment, allowing water to flow between the stones.
Rounded stones are commonly used as a top stone layer where the heater manufacturer permits them. Stack loosely and follow your heater’s stone-loading instructions to maintain airflow. Check its required stone capacity before ordering, as more than one box may be needed.
Harvia recommends replacing sauna stones every 1–2 years, depending on frequency of use. Inspect stones regularly and replace any that show cracking or crumbling.

Harvia Sauna Heater Stones, Rounded Olivine, 5-10cm, 33lbs Review Summary
What people like
Pros
- Excellent Heat Retention: The dense olivine diabase material holds heat effectively for a consistent sauna experience.
- Soft Steam Production: The rounded surface allows water to flow and evaporate in a way that creates a more gentle and pleasant steam.
- Attractive Aesthetic Design: The smooth, rounded appearance provides a high-end, professional look compared to traditional split stones.
- Heating Element Protection: The lack of sharp edges reduces the risk of damaging or scratching the delicate heating coils during installation and use.
Cons
- Higher Price Point: These rounded stones are generally more expensive than standard split olivine stones.
- Large Stone Size: At 5-10cm, they may be too bulky for smaller, compact electric heaters with tight spaces.
- Initial Dust Residue: Some users noted that the stones require thorough washing before the first use to remove stone dust.
- Slower Initial Heating: Because of their rounded shape and mass, they may take slightly longer to reach peak temperature compared to smaller, jagged rocks.
