Custom saunas

Cold Spring

A forever sauna for your forever home.

The ultimate luxury sauna. Designed for the property, built as a finished building, and made to be lived with for as long as the house stands.

So much more than a kit.

Cold Spring arrives fully assembled. Factory built. Stud-framed walls, insulation, a 50-year metal roof, exterior siding, and interior cladding, with options you specify. Built in America. You repair and replace it the way you would the house, so it stays on the property for the life of the property.
