Cross-Laminated Timber Construction
A solid 60 mm timber structure, not standard cladding.
Swift Fit saunas begins with Cross-Laminated Timber, or CLT: timber layers bonded in alternating directions so the panel becomes stronger and more stable than a single-direction board.
It gives the room a modern honesty: the timber is not just a surface treatment, but part of how the sauna is built, finished, and experienced.
Because the panels arrive prefabricated and precision-machined, the structure comes together efficiently on site while keeping the room solid, stable, and refined.

CLT Construction
The Large Outdoor is built from prefabricated cross-laminated timber panels, not a light framed shell with decorative cladding. The CLT wall, floor, roof, and bench elements form the sauna structure itself, giving the room a solid architectural feel while still allowing fast installation. Internal and external timber surfaces are part of this engineered panel system, with final timber finish options confirmed at order.
Exterior · Thermo Spruce with Black Finish
The standard exterior uses Thermo Spruce external lamella with a Black finish, giving the Large Outdoor a calm, sculptural presence against garden, terrace, pool, or wellness architecture. Vertical grooves add rhythm to the surface, while the darker finish works with the black aluminium glass facade to create a unified, restrained profile.
Glass Facade · 8 mm Tempered Glass
The facade uses a black aluminium glass door and two black aluminium window elements, each specified with 8 mm tempered glass. The door includes aluminium hinges and handle, EPDM seals, and reversible configuration, while the window elements use EPDM seals for a clean, durable architectural frontage.
Roof · EPDM Membrane
The Large Outdoor roof system includes an EPDM membrane with adhesives and aluminium roof verge elements. It protects the CLT body while keeping the sauna profile clean, modern, and suitable for outdoor installation.
Interior & Bench · CLT Sauna Elements
Inside, the CLT surfaces continue the architectural language of the shell. The interior lamella may be Natural Spruce, Thermo Spruce, or Thermo Abachi depending on specification, with vertical grooves on the walls and ceiling, smooth floor surfaces, and CLT upper bench, lower bench, and bench support elements forming the sauna’s clean timber posture.
Services · Concealed Cable Provision and Ventilation
The sauna is prepared with provision for hidden cable installation for the LED set, heater, and control unit, keeping the finished space visually clean when compatible equipment is specified. Natural ventilation is handled through wall openings with grills, including an inlet and an adjustable outlet, giving the cabin a simple, integrated airflow system.
Each sauna includes its standard bench configuration, selected to suit the model, room size, and heat layout. Alternative bench styles may be available depending on the sauna range, model, and configuration, with final layout, lighting impact, and pricing confirmed before order.
Available options are confirmed during your private consultation. Some layouts may require additional timber, adjusted lighting, or model-specific changes.
Across wellness research and performance culture, sauna bathing continues to be studied for its role in recovery, circulation, and ritual.
You get used to everything. 88 degrees in the sauna used to feel way hotter. Now it almost feels normal. I’m trying to get in here 4 times a week. The benefits are tangible. One of the wildest feelings you can experience is when you do 20 minutes in a hot sauna and then 2 in a cold plunge, and then back to the sauna.
The latest data point to: i) 57 minutes of hot sauna per week ii) 11 minutes of cold exposure per week as reliable thresholds to derive major benefits on metabolism, insulin and growth hormone pathways. (Can be done same or separate days) (Ideal temp: uncomfortable but safe)
I have been hitting up my home sauna 5 days a week and every time I feel great afterward. Regular sauna use has been associated with up to a 40% reduced risk of pneumonia and increases white blood cell numbers and heat shock proteins. Thirty minutes at 73°C boosts hsp70 by 50% in healthy people.

The OneEighty Large Outdoor Sauna is designed for fast assembly, with assembly time approximately 4-6 hours, depending on site preparation and experience. Electrical work, heater connection, and any required site preparation should still be completed by qualified professionals.
No. The fast assembly comes from factory-machined CLT elements, prepared openings, and a complete prefabricated component system. The result is premium timber construction with a shorter assembly timeline, not a lightweight or temporary sauna.
The OneEighty Large Outdoor Sauna has external assembled dimensions of 1920 x 1998 x 2300 mm. The internal dimensions are 1817 x 1878 x 2050 mm.
The standard exterior finish for this listing is Thermo Spruce external lamella with a Black finish, giving the sauna a darker architectural profile.
CLT stands for cross-laminated timber. The sauna uses 3-ply CLT wall, floor, roof, and bench elements engineered for structural stability, precision, and efficient assembly.
No. It is a prefabricated CLT outdoor sauna kit, but the structure is made from substantial cross-laminated timber elements. The kit format is about precision and assembly efficiency, not reducing build quality.
The Large Outdoor sauna uses a black aluminium glass door and two black aluminium window elements with 8 mm tempered glass. Glass colour options include grey, clear, or bronze.
The outdoor roof system includes an EPDM membrane with adhesives and aluminium roof verge elements.
Yes. Natural ventilation is included through a wall inlet covered with a grill and an adjustable wall outlet covered with a grill.
No. The LED set, heater, and control unit are not included in the technical sheet. The sauna includes provision for hidden cable installation for compatible equipment, depending on the selected heater, lighting, and control setup.
Yes. The standard listing is based on the 180-O2020L configuration, which includes the larger L-shaped bench layout with two upper bench elements and one lower bench element. A straight-bench version, model 180-O2020, is also available on request. Final configuration, weight, and pricing should be confirmed at time of order.
CLT stands for cross-laminated timber. Instead of a standard framed sauna with decorative cladding, the OneEighty sauna body is made from engineered timber panels that form the wall, roof, floor, and bench structure. The visible internal and external timber surfaces are part of that panel system, with final timber finish options confirmed at order.
