Wood Heater For Saunas - Harvia M3

Starting at $1,187 CDN

The Harvia M3 is widely considered the industry standard for small-to-medium wood-fired saunas. It strikes a balance between traditional Finnish craftsmanship and modern efficiency, making it a go-to choice for backyard barrel saunas and off-grid cabins.

 

The Harvia M3 is a classically designed wood-burning heater finished in an elegant graphite black with a stainless steel air-flow spoiler. Designed specifically for smaller spaces (up to 459 cubic feet), it focuses on rapid heating and efficient air circulation to provide a soft, consistent steam.

 

Its standout feature is the tempered glass door, which allows the warm glow of the fire to light the sauna, enhancing the sensory experience of a traditional wood-fired bath. It is highly durable and can be customized with accessories like a chimney-mounted water tank, making it as practical as it is aesthetic.
