Natural Rounded Sauna Stones for Softer Steam and Enhanced Sauna Comfort
The Harvia R-991 sauna heater stones are crafted from premium rounded olivine diabase and designed to create a softer, more relaxing sauna experience. Inspired by naturally rounded stones found in river rapids, these stones bring a smoother visual appearance while supporting a gentler and more evenly distributed steam effect.
Their rounded design allows water to flow more easily into lower stone layers, increasing contact with heated surfaces and generating softer steam characteristics. Designed for use as a top-layer stone arrangement, they help create a balanced sauna atmosphere while maintaining airflow throughout the heater structure.
Selected for cleanliness, safety, and dependable performance, these genuine Harvia stones are ideal for creating a more refined sauna experience.
