CLT Structure · Fast Assembly, Permanent Feel

Premium timber construction without the long build timeline.

The Large Outdoor is built from cross-laminated timber wall, floor, roof, and bench elements, with 3-ply CLT panels engineered for strength, stability, and precision. This gives the sauna a substantial architectural feel, while allowing assembly in approximately 4-6 hours, depending on site preparation and experience.

Premium Home Saunas & Sauna Timbers Australia

Exterior · Thermo Spruce with Black Finish

A dark architectural shell with Nordic discipline.

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.

Premium Home Saunas & Sauna Timbers Australia

Glass Facade · 8 mm Tempered Glass

A full glass face, framed with precision.

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.

Premium Home Saunas & Sauna Timbers Australia

Roof · EPDM Membrane and Aluminium Verge

Protection detailed into the architecture.

The outdoor roof system includes an EPDM membrane with adhesives, supported by aluminium roof verge elements. It gives the sauna a clean, flat modern profile while protecting the CLT structure as part of a complete outdoor installation.

Premium Home Saunas & Sauna Timbers Australia

Interior & Bench · CLT Sauna Elements

A timber room made for heat, stillness, and permanence.

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 quiet engineering behind the finished room.

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.

On Heat

From the literature.

Across wellness research and performance culture, sauna bathing continues to be studied for its role in recovery, circulation, and ritual.

joe rogan

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.

Common questions

OneEighty Large Outdoor Sauna FAQs

Key details on the OneEighty Large Outdoor Sauna, including CLT construction, dimensions, materials, glass, roof system, ventilation, delivery, and electrical requirements.
How long does the OneEighty Large Outdoor Sauna take to assemble?

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.

Is fast assembly a compromise on quality?

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.

What are the dimensions of the OneEighty Large Outdoor 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.

What is the standard exterior finish for this Large Outdoor model?

The standard exterior finish for this listing is Thermo Spruce external lamella with a Black finish, giving the sauna a darker architectural profile.

What is CLT construction in this sauna?

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.

Is the OneEighty Outdoor Sauna a lightweight kit sauna?

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.

What glass is used in the Large Outdoor sauna?

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.

What roof system does the outdoor sauna include?

The outdoor roof system includes an EPDM membrane with adhesives and aluminium roof verge elements.

Does the sauna include ventilation?

Yes. Natural ventilation is included through a wall inlet covered with a grill and an adjustable wall outlet covered with a grill.

Are the heater, lighting, and control unit included?

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.

Is the Large Outdoor available with different bench configurations?

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.
