Narvi Net Around Smoke Pipe — Stainless Steel

Sauna heat radiates upward as well as sideways — and the chimney directly above a wood-burning stove is one of the hottest surfaces in the room. This stainless-steel mesh cagewraps around that smoke pipe and lets you fill it with sauna stones.

The result is dramatic: significantly more thermal mass in the room, radiant heat cascading downward from above your head, and a bigger, softer, longer-lasting plume of steam when you throw water over the top stones. It's the classic upgrade for anyone building a hot, humid, proper Finnish-style sauna — and once you've felt the difference, you won't want to fire a stove without one.
