Designed for small to medium-sized traditional saunas (ranging from 150 to 450 cubic feet), the M3 delivers the iconic, soft steam (löyly) and gentle warmth that only a wood-fired sauna can provide.

Engineered in Finland, the M3 features a classic, elegant graphite black exterior complemented by a stainless steel spoiler on top, ensuring efficient heat circulation and long-lasting durability. The glass door allows the soothing, warm glow of the fire to enhance your relaxation experience, turning every sauna session into a multisensory escape.
