Sauna Stones, Rounded Olivine, 2"- 4" , 33lbs

Olivine diabase is a tough rock that is able to withstand the high temperatures in a sauna without cracking or breaking easily. This is important because cracked stones can trap moisture and eventually crumble, reducing their effectiveness and potentially damaging the heater. Olivine diabase has a high density, which means it absorbs and stores heat well. This allows the stones to stay hot for a longer period, providing consistent heat throughout your sauna session.

When water is poured on the hot stones, it creates soft, gentle steam. This is because the olivine diabase heats evenly and releases the heat gradually, avoiding the harsh flash of steam you might get with some other materials.

Overall, olivine diabase offers a good balance of durability, heat retention, and steam production, making it a smart choice for sauna stones.

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)
