What makes this sauna unique
Designed to withstand the seasons
The Onyxia Barrel sauna is designed for long-lasting outdoor installation. Its ThermoWood® cladding—wood heat-treated at high temperature with no chemical additives—offers enhanced dimensional stability and increased resistance to moisture, climate variations, and the natural elements.
This natural treatment optimizes the wood’s longevity while preserving its aesthetics. Season after season, Onyxia Barrel retains its look and performance, perfectly aligned with a premium positioning.
The essence of the Finnish ritual
Equipped with an electric stove with volcanic stones, Onyxia Barrel recreates the traditional Nordic sauna experience. Water poured over the heated stones releases an even steam that delivers controlled, gradual heat.
The atmosphere becomes immersive and enveloping, ideal for deep release. A contemporary interpretation of the Finnish ritual, respectful of its original codes.
Designed and manufactured in Europe
Onyxia Barrel is designed and assembled in Europe to exacting standards of precision and quality. Every manufacturing step is subject to rigorous control, from materials to finishes.
This craftsmanship ensures lasting structural strength, refined aesthetics, and long-term technical reliability. A consistent choice for a truly premium sauna.
The authenticity of a wood fire
Compatible with a wood-burning stove, Onyxia Barrel lets you rediscover the original experience of the traditional sauna. The heat becomes more organic, more enveloping, more alive.
The gradual rise in temperature and the crackle of the fire create a unique sensory atmosphere, turning each session into a moment of deep disconnection.
