Harvia R-991 Sauna Stones: rounded stones that let water reach deeper for softer steam
The Harvia R-991 Sauna Stones is a box of rounded gray olivine diabase stones for sauna heaters. Water flows down their curved surfaces to the stones below, reaching more hot stone for softer steam. Each box holds 33 pounds of 2 to 4 inch stones. You can use them as the top layer in a Harvia sauna heater.
Leave space between the stones so air can move through the heater. If your heater has little room for stones, put angular stones underneath these rounded ones. These stones are sold only with a Harvia heater or stove order. Prefer white stones on top? See the Harvia AC4000 Decorative Stones. The Harvia R-991 Sauna Stones ships free from Norse Steam with No Sales Tax (except WY) and our 100% price match guarantee.
