Product Description

Natural Rounded Sauna Stones for Softer Steam and Enhanced Heat Distribution

The Harvia R-995 sauna heater stones are crafted from rounded olivine diabase and designed to create a softer, more balanced sauna experience. Inspired by naturally rounded stones found in powerful river rapids, these stones provide a smoother appearance while supporting gentle steam generation and improved water distribution.

Their rounded shape allows water to flow more easily into lower stone layers, increasing contact with heated surfaces and creating a softer steam effect. When used as a top layer in sauna heaters, these stones help deliver a more comfortable sauna atmosphere while maintaining airflow and heat performance.

For optimized results, rounded top-layer stones can be paired with angular lower-layer stones to support efficient heat transfer and balanced steam production.
