unwind in your own outdoor sauna

A modern outdoor sauna, with its unique cubical shape, made to effortlessly relax while enjoying the benefits and privacy of your own garden. Thermalux redefines the concept of home wellness by giving it a true upgrade. Focussing on the user experience and making it all about your well-being.

Our outdoor saunas are designed to either be placed freestanding or combined with other wellness products. A standard version or a fully custom-maid model that really matches your personality and garden design.

Product characteristics

Standard or tailor-made?

Each model can be offered in 3 versions: Aluminum (ALU), Wood (PUU) or Mirror Aluminum (MIR).

Aluminum (ALU)

The aluminum version is protected against all weather conditions with a UV-resistant polyester paint. In addition to standard white, black or stainless steel look you can choose from all RAL colors to, for example, match your sauna with the color of your facade or windows.

The standard interior finish is white, black or wood. We finish everything nicely with thermo ayous planking and ensure that all materials are resistant to heat and moisture.

Wood (PUU)

The wooden version (PUU) is made entirely of high-quality thermowood pine, both on the inside and outside. The benches are covered with thermo ayous.

Mirror Aluminum (MIR)

The mirror sauna consists of a UV-resistant mirror aluminum and mirror glass, so that it completely blends into the environment. The inside again consists of thermowood.

Our outdoor saunas are available in a number of standard sizes and configurations, but we are also happy to draw up a custom design. Would you like to create extra space by adding an overhang, so that you can provide a shower or storage room? A combination with jacuzzi or outdoor spa? You can combine and personalize endlessly.

Le sauna a traversé la France et a été installé à Marseille ! Il séduit tous les hôtes de passage dans notre maison (y compris nous même très adepte des saunas). De très bonne facture et magnifiquement design il s'intègre parfaitement dans notre jardin. Je recommande vivement.

Prachtig product! We genieten dagelijks van de luxe en rust die onze Thermalux sauna geeft. De berging is ruim en het cederhout zeer proper afgewerkt. Een aanrader!

De bestelling en de plaatsing van onze IR sauna verliep zeer vlot. Ook enkele kleine aanpassingen nadien werden vakkundig opgelost. Goede service dus van begin tot einde.

I ordered my Thermalux sauna without having seen it in reality. A Belgian sauna to Sweden! I simply took a chance. But I was not disappointed. The sauna became "the cherry on the cake" at our retreat by the lake.
