Garden room project · Sanctum Garden Studios

Sauna created in a Sanctum garden studio

A 3.6m × 3m cedar studio by Sanctum Garden Studios, left unfinished inside so the owner could fit out the sauna.

Sanctum Garden Studio converted into a sauna
Sanctum Garden Studios  3.6m × 3m cedar studio fitted out as a sauna

Incorporating a sauna into a garden studio is a popular choice, and many bespoke garden studio designers can accommodate this as part of their overall project. For this particular build, Sanctum Garden Studios crafted a bespoke studio, allowing their customer to install the sauna themselves.

Sanctum Garden Studios designed a customised version of their Contemporary Overhang Range of Cedar studios, working closely with their customer to ensure the building met precise requirements, including the size and positioning of windows and specific finishes. The final structure measures 3.6 metres by 3 metres, offering a compact yet functional footprint.

At a glance

  • Size: 3.6m × 3m, a bespoke version of the Contemporary Overhang range, with window sizes, positions and finishes agreed with the customer.
  • Layout: A partition wall and a specialist sauna door divide the building into a lobby and the sauna room.
  • Shell: Sanctum insulated the lobby and lined it in OSB, and left the sauna room as an open frame with no plasterboard or flooring.
  • Fit-out: The customer insulated and finished the sauna room to suit its use.
  • Company: Sanctum Garden Studios, who usually supply a finished interior but built this one as a shell for the owner to complete.

Fit-out

A collaborative approach to sauna installation

While Sanctum Garden Studios typically provide a fully finished interior, the customer opted for a more hands-on approach. The interior was left unfinished, with no plasterboard or flooring installed. This allowed the customer to personally fit out the space to meet the exacting requirements of a sauna.

The studio was divided into two rooms using a partition wall and a specialist sauna door. Sanctum insulated and lined the lobby area with OSB boards, while the main sauna space was left with an open frame for the customer to insulate and finish independently.

The result is a stylish and practical sauna studio, showcasing the collaborative efforts between Sanctum Garden Studios and their customer.
