Description
The Harvia Pro 20 BK Sauna Stove Package is a complete black wood-burning sauna solution built around the powerful Pro 20 stove. This all-inclusive package comes with the Pro 20 Sauna Stove, Protective Bedding, Protective Sheath, Chimney Kit, Chimney Extension, and Sauna Stones — everything you need to deliver a satisfying sauna bath experience for larger sauna rooms.
Designed for sauna rooms from 283 to 706 cubic feet, the Pro 20 is one of Harvia's most capable residential wood-burning stoves. With stainless steel construction, a graphite black finish, and an 88-pound stone capacity, it delivers the powerful, authentic heat that serious sauna enthusiasts demand.
Wood-Burning Performance
The Pro 20 is rated at 24kW — significantly more powerful than most residential wood-burning stoves — making it the ideal choice for larger sauna rooms up to 706 cubic feet. Its stainless steel construction and adjustable feet ensure long-term durability and easy installation on any floor surface, including sloping floors.
The stove accepts firewood up to 15 inches (39 cm) in length with a diameter of 3 to 6 inches (8–15 cm). The flue connection is located at both the top and back for flexible routing, and the 3-sided protective sheath reduces safety distances to combustible materials for easier room integration.
