Harvia Decorative Red Granite Sauna Heater Stones, Split-Face, 5-10cm (AC5000)

Add a distinctive touch to the surface of your sauna heater with the Harvia AC5000 Red Granite decorative sauna stones. Sold in 44.1 lbs (20 kg) boxes.

Made from gorgeous red granite, the reddish hue creates a warm, toasty atmosphere to improve your sauna heater's aesthetic. Stones must be piled loosely upon traditional high-density sauna stones to ensure good air circulation and efficient, soft steam production.

• Sauna heater stones are made of a beautiful split-face red granite to add a stunning decorative element to your heater.
• Must be stacked loosely without coming in contact with the heating element to ensure good air circulation.
• Less durable than traditional sauna heater stones (may be subject to cracking or discoloration after prolonged use)
• Does not contain harmful ingredients.

This item is not tied to a specific heater or stove model — it suits any Harvia sauna.

• Sauna stones are not a decorative topping — they are the thermal mass that makes a sauna a sauna.
• Rinse before loading to wash off dust.
• Stack loosely by hand, largest at the bottom. Never wedge, hammer or pack them.
• Re-stack once a year and replace any that have split or crumbled.

How many boxes of stones do I need?

Each box holds 44 lb, except the rounded R-991 at 33 lb. Your heater's product page gives its stone capacity and the number of boxes Harvia specifies. Order one box more than the minimum so you can set aside any that will not stack cleanly.

How often should sauna stones be replaced?

Re-stack them once a year and replace any that have cracked or crumbled. Stones break down with thermal cycling, and a bed of broken fragments chokes the airflow the heater needs to survive.
