Onyx Traditional Sauna

Modern Design. Timeless Heat. Built to Endure.

Introducing the Onyx Traditional Sauna — a bold fusion of modern engineering and authentic Finnish sauna tradition. Crafted with a full aluminium exterior frame and a warm Canadian Hemlock interior, the Onyx delivers both unmatched durability and a deeply restorative sauna experience.

The Traditional Sauna Experience

At the core of the Onyx Sauna lies the Harvia Vega BC45 BC60 a powerful 4.5KW & 6KW electric sauna heater engineered in Finland to deliver the true "löyly" experience the soft, enveloping steam that defines an authentic sauna.

Unlike infrared systems, which rely on direct heat and lack steam, the Vega uses hot stones to heat the room evenly, reaching higher temperatures and allowing you to control the humidity by pouring water over the rocks. This creates a deeply immersive environment perfect for both dry heat sessions and the classic steam sauna ritual.

The result is superior heat distribution, deeper muscle relaxation, and a more genuine sauna experience  just as it’s been enjoyed in Finland for generations.

Built for a Lifetime: The Strength of aluminium

The Onyx Sauna’s aluminium exterior frame is designed with longevity and resilience in mind. aluminium is naturally resistant to rust, corrosion, and weathering, making it an ideal choice for outdoor environments. Its strength ensures long-term structural stability, while its low-maintenance surface retains a clean, modern finish for years to come.

Combined with its sleek aesthetic and durable performance, aluminium brings both form and function to your wellness space  ensuring the Onyx stands the test of time in any setting.
