welcome to your own outdoor sauna

An outdoor sauna that comes in a timeless and modern outfit. Say yes to relaxing in your own garden. Thermalux really redefines the concept of home wellness. Making it all about relaxing in true elegance, with a minimalist and contemporary design.

Our outdoor saunas also come with a storage room. You can easily use it as a technical space for your pool or just a place to store your stuff. Quickly want to change before stepping into the sauna? This additional space can also be transformed into a changing room.

Product characteristics

Our outdoor sauna with storage design is the same as our outdoor equivalent, isolating it and making it waterproof. The storage is made from the same materials and can also be finished in osb. 

The outside of the sauna is covered with aluminum, thermo ayous, or a combination of both. We put on a UV-resistant coat of polyester lacquer, making it impermeable. That way, your steam room is ready to take on all types of weather conditions.

For the outside finish, you can either go for a full inox look or you can pick a RAL colour of your choice, blending it perfectly with the colour and design of your house or windows.

The inside is covered with thermo ayous and our finish is standard black or white, but the choice is completely yours. We make sure all of the materials are heat and humidity resistant.

Prachtige buitensauna; voortreffelijke service; we zijn er hartstikke blij mee. Een genot om naar te kijken en in te zitten. Dankjewel Mario!

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.

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.

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.

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!
