CLT Structure · Compact Format, Real Substance
The Small Outdoor is built from cross-laminated timber wall, floor, roof, and bench elements, with 3-ply CLT panels engineered for strength, stiffness, and dimensional stability. Its 2×2 element format gives the sauna a compact architectural footprint while preserving the solid, permanent feel expected from OneEighty’s outdoor system.
Exterior · Thermo Spruce with Black Coating
The standard finish is Thermo Spruce with Black Coating, giving the Small Outdoor a crisp, architectural presence across its exterior and interior timber surfaces. Vertical grooves bring proportion and rhythm to the compact body, while the darker finish works with the black aluminium glass facade to make the sauna feel composed rather than small.
Glass Facade · 8 mm Tempered Glass
The facade uses a black aluminium glass door and one black aluminium window element, specified with 8 mm tempered glass; glass colour options Grey, clear, or bronze. The result is a generous sense of light and transparency in a smaller footprint, without losing the calm enclosure that makes the sauna feel private.
Roof · EPDM Membrane and Aluminium Verge
The outdoor roof system includes an EPDM membrane with adhesives and aluminium roof verge elements. It protects the CLT body while keeping the Small Outdoor’s silhouette sharp, modern, and deliberately understated.
Interior & Bench · Thermo Spruce with Black Coating
Inside, the sauna continues the same dark, architectural material language. Thermo Spruce with Black Coating carries through the interior wall and ceiling lamella, floor surfaces, and bench elements, with vertical grooves on the walls and ceiling and smooth CLT upper bench, lower bench, and bench support elements arranged for efficient comfort.
Services · Ventilation, Drainage, and Hidden Wiring
The Small Outdoor integrates the service details that keep the finished room resolved: air intake and air extraction through wall openings with grills, an adjustable outlet, drainage with a 50 mm opening and stainless steel cover, and concealed wiring paths for power supply, lighting, temperature sensor, heater controller, door sensor, and main module.
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 Small Outdoor Sauna is designed for fast assembly, with a assembly time approximately 4-5 hours, depending on site preparation and experience time once the site is prepared. 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 Small Outdoor Sauna has external assembled dimensions of 1300 x 1378 x 2300 mm. The internal dimensions are 1197 x 1258 x 2050 mm.
The standard finish for this listing is Thermo Spruce with Black Coating for the interior and exterior, 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.
