Barrel saunas have become one of the most popular outdoor wellness solutions for gardens, terraces, and countryside retreats. Their rounded shape allows for fast and even heating while offering a unique, elegant aesthetic that stands out in any outdoor space.
Today we present one of our standout projects: a compact 2.4 × 2.4 m barrel sauna built with thermally treated wood, fitted with a premium mirror-glass front, and equipped with the iconic Harvia M3 wood-burning stove and chimney kit.
A combination designed to provide an authentic, durable, and visually striking sauna experience.
This sauna is built entirely from thermowood, one of the most durable and stable materials for outdoor constructions. The thermal-treatment process uses only heat and steam – no chemicals – to significantly enhance the wood’s performance.
Thanks to these advantages, thermowood is the perfect choice for saunas, especially those exposed to demanding outdoor environments.
One of the most striking features of this sauna is its mirror-glass front panel, offering both functionality and visual impact.
This upgraded façade transforms the sauna into a premium architectural feature, elevating the look of any garden or outdoor area.
