Description
The Cozy Heat Premium Rounded Sauna Stones are carefully selected natural stones designed to provide optimal heat retention and soft steam for sauna heaters and wood-burning sauna stoves.
These premium stones are made from olivine diabase, a dense volcanic rock known for its excellent durability and ability to withstand extreme temperatures. Because of this unique composition, the stones heat evenly and retain warmth for long periods, creating a consistent and comfortable sauna environment.
Unlike split-face stones, the rounded design allows water to flow easily between the stones, reaching lower layers before evaporating. This increases the surface area exposed to water and results in a softer, smoother steam experience compared to sharper stone types.
Inspired by naturally rounded stones found in river rapids, these stones add a more organic aesthetic to your sauna heater while also enhancing overall steam performance.
Each box contains 44 pounds of stones sized 10–15 cm (4–6 inches), ideal for use in Cozy sauna heaters and stoves.
Note: These sauna stones are available only with the purchase of a Cozy sauna heater or stove.
Heat & Steam Performance
Olivine diabase sauna stones are widely regarded as one of the best materials for sauna heating due to their strength and thermal properties.
Key advantages include:
• High heat storage capacity
• Even heat distribution
• Excellent resistance to cracking
• Long service life under repeated heating cycles
When water is poured over the heated stones, the water travels through the stone layers before evaporating. This creates a gentle and relaxing steam instead of sudden bursts of heat, making the sauna experience smoother and more comfortable.

Installation & Usage
For best performance when loading sauna stones:
-
Place larger stones at the bottom of the heater.
-
Keep the stones loosely stacked to maintain airflow.
-
Avoid tightly packing the stones inside the heater.
-
Replace cracked or worn stones periodically to maintain performance.
In heaters with smaller stone capacity, it may be beneficial to place angular stones at the bottom layer to maximize heating surface area while using rounded stones on top for improved steam.
