Vantorra 337 Barrel Sauna, 220 cm Diameter

Walls on Vantorra 337 run 42 mm thick, which is what actually holds heat in once the sun goes down.

Ventilation is a low inlet and a high outlet, both adjustable — that's what actually controls how a sauna feels, more than the heater does.

It is built in thermo-treated spruce: spruce heat-treated to change its cell structure, so it resists rot and moisture without any chemical preservative. The heater is the part that actually wears — it's a bolt-in unit, not built into the walls.

Care

Reapply exterior oil once a year and check the door seal each spring. Sweep snow off the roof rather than letting it sit — the curve sheds it, but only if it's given the chance.
