The Jonas Small sauna by Celsium makes its debut in this first model photoshoot, capturing the perfect blend of Scandinavian minimalism and authentic craftsmanship. Compact yet refined, it is designed for those who seek a private outdoor sauna retreat with a strong sense of style and wellness.
What makes this model truly unique is its façade, crafted from Shou Sugi Ban wood – a traditional Japanese technique of charring timber. This finish not only adds a bold architectural statement but also enhances durability, weather resistance, and timeless beauty.
The photos highlight the contrast between the dark, textured exterior and the warm natural wood interior, creating a sanctuary of luxury wellness and slow living. Perfect for gardens, lakesides, or modern outdoor living spaces, the Jonas Small sauna embodies Celsium’s vision: merging design, nature, and the therapeutic benefits of sauna rituals.
