Aluminium Finish (ALU)

As the original Thermalux saunas, the ALU model comes in a timeless aluminium finish. As well as the basic options of black, white or inox look, you can choose any RAL colour that suits your palette scheme, allowing you to customise your sauna to blend perfectly with the colour of your existing outdoor features. Suitable for all weather conditions, the Thermalux ALU outdoor sauna exterior, available with or without an overhang has a UV-resistant external coat of polyester lacquer, and all materials are heat and humidity resistant.

White Aluminium Standard Finnish Outside Sauna

Aluminium Standard
Finnish Sauna

Our aluminium outdoor sauna’s base model is the Finnish sauna. Also known as a dry sauna, it provides a range of health benefits including detoxification, skin care, improved immunity and muscle relaxation. This minimalist and contemporary sauna is the perfect addition to your outdoor space and can be customised and combined with other Thermalux outdoor wellness products.

INOX Look Aluminium Infrared Garden Sauna

Aluminium Infrared Sauna

The aluminium, outdoor infrared sauna is the first of a new generation of luxury infrared saunas that offers a minimalist aesthetic design and invisible heater panels. The interiors of our infrared sauna models are covered with a thermally modified, sustainable hardwood called thermo ayous, creating a resistant, soft and elegant finish. For the perfect look and comfort, we added two floating benches that make for a spacious and luxurious place for relaxation.

White Aluminium Bio - Sauna

Aluminium Bio-Sauna

Our outdoor aluminium finish bio-saunas or sanariums create a tropical atmosphere within the privacy of your own garden, with the option to add aroma infusions to enhance your calming experience. A bio-sauna is the perfect combination of the Finnish sauna’s warmth with the steam bath’s humidity. This moistness is introduced in a particularly gentle and circulation-friendly dose, generally between 50-70%. Our bio-sauna is created with the optional combi oven giving auto steam function.

Invisible Sauna


We are delighted to launch the newest addition to our Aluminium Finish range, the Invisible Sauna, allowing you to relax in an extra private atmosphere. Entirely covered with mirror aluminium and mirror glass on the outside, Thermalux’s Invisible Sauna is very easy to maintain, with just a quick rinse of water. The most unique feature of our Sauna is that it sharply reflects its surroundings and blends in perfectly into the landscape, making itself one with any environment.

Aluminium Outdoor Sauna Combinations

All of our aluminium outdoor saunas can be free-standing or combined with another model: including whirlpool with shower, sauna and infrared sauna room, sauna and steam bath, infrared and steam bath. We can also add a toilet room, relaxation area or changing room, and every section can be interconnected or separate from each other. Other customisable options include specified external and internal RAL colours, double glazed walls, privacy glass, or even a Wi-Fi module to connect with your phone or home automation system.
