Harvia Rounded Olivine Diabase Sauna Stones (5–10 cm)

PLEASE NOTE: In some cases, sauna stones are only available with the purchase of a sauna heater or stove. Due to intermittent stone shortages, we may not be able to fulfill standalone stone orders at this time. Please check with us before placing an order.

The Harvia Rounded Olivine Diabase sauna stones bring a natural, river-polished look to your sauna while enhancing the quality of steam. Their rounded shape allows water to flow smoothly through the stone layers, producing a softer, more enveloping steam that improves comfort and relaxation.

For optimal performance, use rounded stones on the top layer and combine them with angular stones at the bottom. This ensures maximum water contact, better heating efficiency, and proper airflow—particularly beneficial in heaters with smaller stone capacities.
