CLT Structure · Medium Format, Serious Engineering
The Medium 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 2×3 element format gives the sauna a generous interior without demanding the footprint of the Large, making it a precise fit for terraces, gardens, and poolside wellness spaces.
Exterior · Thermo Spruce with Black Coating
The standard exterior uses Thermo Spruce external lamella with a Black finish, giving the Medium Outdoor a quiet, architectural presence. Vertical grooves bring rhythm to the surface, while the darker timber works with the black aluminium glass facade to create a clean, confident 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 result is open, modern, and exact: a sauna that feels connected to its setting while still preserving the calm enclosure of a private heat room.
Roof · EPDM Membrane and Aluminium Verge
The outdoor roof system includes an EPDM membrane with adhesives and aluminium roof verge elements. It gives the Medium Outdoor a flat, modern roofline while protecting the CLT structure as part of a complete outdoor installation.
Interior & Bench · CLT Sauna Elements
Inside, the sauna continues the honest material language of its structure. 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 a calm, functional layout.
Services · Ventilation, Drainage, and Hidden Wiring
The Medium Outdoor integrates the service details that make the finished room feel clean: 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 Medium 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 Medium Outdoor Sauna has external assembled dimensions of 1300 x 1998 x 2300 mm. The internal dimensions are 1197 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.
