Sourced from the ancient bedrock of Northwestern Ontario, Hiillos sauna stones are dense, thermally stable igneous rock with the same geological character as traditional Finnish sauna stone. Heat-tested for performance and sized for optimal löyly—the steam created when water meets hot stones. Proudly Canadian.

Available in 10 kg and 16 kg boxes. One 16 kg box provides the amount needed for a wall-mounted Fenno sauna stove.

Available for in-store pickup at Finnport, Thunder Bay. Shipping available by arrangement—contact us for details.
