Hand-built in our workshop, the way saunas are made in Finland. We use teak, pine and red cedar — kiln-dried, food-safe finishes only.
Delivered and installed nationwide. Heater wired, first heat-up with you on-site.
The same 3D model you configure in the designer is the sauna we hand-build. Drag the handle to compare — or just watch it change.
