Description
The Narvi Stone Cage is a functional sauna accessory designed to improve heat utilization and enhance steam production in wood-burning sauna systems. Installed around the chimney flue, the stone cage allows additional sauna stones to absorb heat from the chimney pipe, increasing overall heat retention in the sauna.
When water is poured over the stones, the heat stored in both the heater stones and the chimney stones helps produce longer-lasting and richer sauna steam. As the water flows from the stone cage down to the heater stones, the steam continues to build, creating a smoother and more consistent sauna experience.
In addition to improving steam performance, the stone cage also helps reduce the required safety distance to nearby combustible materials, providing added flexibility when installing sauna heaters.
The cage features a durable black steel design that blends seamlessly with sauna chimney systems. Multiple stone cages can also be stacked on top of each other to create a visually striking sauna heater setup while further improving heat retention.
Designed, engineered, and manufactured in Finland, the Narvi Stone Cage offers both functional performance and stylish sauna aesthetics.
