Rounded Olivine Diabase stones are specially crafted to replicate the smooth, natural look of river-worn rocks while offering enhanced sauna performance. Their rounded shape encourages a soft steam effect—when water is poured over the top layer, it flows evenly between the stones, reaching lower layers and increasing the heated surface area. This process produces abundant steam with a gentler, more comfortable feel compared to traditional stone arrangements.

Note: Available only with the purchase of a Harvia sauna heater or stove.

  • Natural Design – Rounded olivine diabase stones mimic smooth riverstones, adding a refined, organic look to your sauna.
  • Premium Quality – Selected for cleanliness, safety, and consistent gray tone.
  • Enhanced Steam Experience – Rounded shape encourages softer, gentler steam by allowing water to flow through to lower stone layers.
