The sauna is constructed primarily from timber, with an exterior defined by vertical wooden cladding that gives the structure a restrained and uniform appearance. Its rectilinear form is designed to sit discreetly within outdoor environments while providing sufficient interior volume for seated sauna use. The Jonas sauna features [built-in wooden benches](https://www.trendhunter.com/trends/tyto) arranged along the perimeter, allowing users to sit or recline during sessions. A large glazed opening is incorporated into one side of the structure, providing outward views and allowing natural light to enter the interior while maintaining heat retention. The glazing is paired with insulated wall panels to support consistent internal temperatures during operation.
