Sauna Heater Stones | Saunum Rounded Olivine Diabase | 33 lb Box 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.
