Ahti 16–24 kW Wood-Burning Sauna Stove

A dependable core component for any sauna, the Ahti Wood-Burning Sauna Stove is a wood-burning sauna stove from Vellpont. Best suited to outdoor and cabin saunas of roughly 8–24 m³ where an electrical supply is impractical; the Ahti needs a class-1 chimney and proper clearances. Built to order in measured batches and backed by the Vellpont support team.

Wellness Benefits

Nothing matches the atmosphere of a wood-fired sauna — the crackle of the fire and the soft, powerful löyly. The Ahti brings that off-grid ritual to lakeside and garden saunas.

Care & Maintenance

Empty the ash pan regularly and sweep the flue at least once a season. Re-stack the stones annually and burn only dry, seasoned wood to keep the glass clear and the stove efficient.
