Who It’s For
Harvia R-991 stones are ideal for sauna owners who want a rounded stone finish and softer steam. They are particularly useful as a top layer when the heater manufacturer’s stone specifications permit this size and material.
Stone Selection & Loading
Stack stones loosely to maintain good airflow and support heater longevity. For heaters with smaller stone capacities, use similarly sized angular stones in the lower layers, as recommended, to provide more heated surface area for water.
Because natural stones vary in shape and size, purchasing an additional box is recommended to give you more options when selecting stones for fit, form, and function. Follow your heater’s instructions for stone type, size, quantity, and placement.
