Olivine diabase sauna stones are engineered to deliver exceptional performance and longevity in high-heat sauna environments. This extremely durable natural stone is resistant to cracking and breaking, even under intense and repeated temperature fluctuations—helping protect your sauna heater from damage caused by crumbling or moisture-trapping stones.

Thanks to its high density, olivine diabase absorbs and stores heat efficiently, allowing the stones to remain hot longer and deliver consistent, even heat throughout your sauna session. When water is poured over the heated stones, they produce a soft, gentle steam, releasing heat gradually and avoiding the sharp, aggressive bursts of steam associated with lower-quality materials.

Balancing durability, superior heat retention, and smooth steam production, olivine diabase is widely regarded as an ideal choice for premium sauna stones—enhancing comfort, performance, and the overall sauna experience.

Only available with the purchase of a Cozy sauna heater or stove.

Please note that each natural stone is unique in shape and size. We recommend purchasing an additional box of sauna stones to allow you to choose the highest quality of stone for fit, form, and function (Additional freight charges will apply).
