  • Thermowood Barrel Sauna With Mirror Glass Front – A Superior Wellness Experience in Your Own Garden

    Why choose a barrel sauna?

    Sauna de Barril de Madera Termotratada

    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.

    Thermowood: the ideal material for outdoor saunas

    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.

    Benefits of thermowood

    • Superior moisture resistance
    • Excellent dimensional stability (minimal warping or swelling)
    • High durability against fungi and insects
    • Warm, elegant colour that enhances any outdoor setting
    • Reduced maintenance compared to untreated wood

    Thanks to these advantages, thermowood is the perfect choice for saunas, especially those exposed to demanding outdoor environments.

    Modern sauna design: mirror-glass front

    One of the most striking features of this sauna is its mirror-glass front panel, offering both functionality and visual impact.

    Advantages of mirror glass

    • Total privacy from the outside
    • Minimalist, contemporary appearance
    • Increased natural light indoors
    • Sense of spaciousness and connection with nature

    This upgraded façade transforms the sauna into a premium architectural feature, elevating the look of any garden or outdoor area.
