Unlike conventional all-wood structures, the Myrtha Stainless Steel Sauna is engineered for exceptional longevity and is backed by a 25-year structural warranty, compared with the typical two- or three-year warranty with traditional technology

Aquatic engineering company Myrtha Wellness has developed a modular stainless steel sauna structure, called Myrtha Stainless Steel Sauna, to increase the life cycle of the thermal facility compared to traditional wooden saunas that often require complete replacement.

Myrtha Wellness is providing a 25-year warranty for the steel structure, which can be adapted for various sauna categories, including:

Finnish saunas
Bio saunas
Soft saunas
Event saunas
Panorama saunas
Outdoor saunas
Bespoke saunas

The interior timber finishes can be renewed or replaced, without modifying the structural frame, which the company describes as a low-cost solution that reduces long-term maintenance and refurbishment costs.

Stefano Cattaneo, global director of Myrtha Wellness, said: “For more than 60 years, Myrtha has redefined excellence in aquatic engineering. The technology that made us the global benchmark for competition pools and Olympic venues is now shaping the future of wellness. 

“This is not simply a new sauna; it’s a completely new construction concept. At its core is a stainless steel structural frame, insulated with high-performance, fire-resistant materials. Unlike conventional all-wood structures, the Myrtha Stainless Steel Sauna is engineered for exceptional longevity and is backed by a 25-year structural warranty, compared with the typical two- or three-year warranty with traditional technology.”

The company also says the steel system allows the integration of high-performance insulation materials that are superior to those possible in conventional all-wood saunas. The benefits include higher energy efficiency, lower heat loss, accelerated heating and reduced energy consumption.

Myrtha Wellness can also engineer the new structure to be seismic-resistant for operations in markets prone to earthquakes.
