Narvi Split-Face Olivine Diabase Sauna Stones 44 lbs

Narvi Split-Face Sauna Stones are designed for traditional sauna heaters that require large, angular stones capable of handling high temperatures and repeated heating cycles. Manufactured from natural olivine diabase, these stones are supplied in a 44 lb box and sized at 10–15 cm, making them suitable for heaters that specify larger stone dimensions for proper airflow and heat retention. Correct stone selection plays a critical role in sauna performance, and these stones are intended to support stable, predictable heater operation.

The split-face (angular) shape allows the stones to stack securely while maintaining airflow channels between them. This structure helps heat circulate evenly throughout the heater and supports efficient steam production when water is applied. Angular stones are commonly used as the primary stone fill in sauna heaters because they create firm stacking layers that resist shifting over time. This helps protect heating elements and supports consistent heat output when installed according to heater requirements.

Olivine diabase is widely used in sauna environments due to its durability under extreme temperature changes. These stones are selected specifically for sauna use rather than decorative or landscaping purposes. Their density and thermal stability help them withstand repeated heating and cooling without premature cracking, supporting long-term performance when stones are inspected and replaced as part of routine sauna maintenance.

The 10–15 cm size range is well suited for medium to large sauna heaters where larger stones are required to maintain correct spacing around heating elements or fire chambers. Using stones outside the recommended size range can restrict airflow or lead to uneven heating, which is why purpose-matched stones such as these are an important component of proper sauna setup. When stacked loosely and correctly, they support balanced heat distribution and responsive steam generation.

Narvi focuses on producing sauna-specific components that align with traditional sauna design principles. These split-face sauna stones are intended for sauna users who value dependable materials, functional design, and components engineered for sustained sauna use. They are suitable for use in both electric and wood-burning sauna heaters that accept stones of this size range, depending on heater specifications.

Whether replacing worn stones or assembling a new heater configuration, the Narvi Split-Face Olivine Diabase Sauna Stones provide a practical, purpose-built option. Proper stone choice directly influences heater performance, steam quality, and long-term reliability, making these stones an essential part of maintaining an authentic and consistent sauna experience.
