Harvia PRO 36 31kW Wood Burning Sauna Stove: Commercial-Grade Performance
The Harvia PRO 36 is built for sauna rooms where a PRO 20 is not enough. 31kW for sauna rooms up to 1,060 cubic feet — large family saunas, club installations, and small commercial facilities. Harvia most powerful conventional wood-burning stove before stepping up to the PRO 50.
Why Buy From RecovAthlete

“The PRO 36 covers the space between serious residential and full commercial — a range where very few products genuinely compete.”
Large home saunas and semi-commercial installations from 700 to 1,060 cubic feet where the PRO 20 runs at its limit.
Club saunas, lodge facilities, and wellness centres that prefer wood-burning heat at high-volume output.

Installation Notes
This stove requires a chimney system running through the wall or ceiling of your sauna room. Most installations use the Harvia chimney kit — WHP1500 (stainless) or WHP1500M (black) — which is built for the standard 4.5 inches (115 mm) flue. For higher ceilings, add extension pipes WHP500 (1.64 ft) or WHP1000 (3.3 ft). A protective sheath is required if the stove is within minimum clearance distance of combustible walls. We confirm the correct chimney kit for your ceiling height before your order ships. Call 866-861-6317 for pre-installation documentation for your contractor.
On the investment: A wood-burning sauna stove built to Harvia's quality standard should last 20–30 years under regular use. Spread across years of daily sessions, the cost per use is much lower than most buyers expect. This is not a piece of equipment you replace on a schedule — it’s one you pass on.

- Harvia PRO 20 24kW — For a smaller sauna, lower output
- Harvia PRO 50 40kW — Very large commercial sauna
