a design steam room that beautifies any garden

That blissful moment of pure well-being, where the warmth of the steam room penetrates your skin and body, giving it a much needed detox. Wellness relaxation is not only made for inside, but is certainly meant for outside enjoyment as well. 

Our steam rooms are made from high-quality and innovative materials and come with a modern and contemporary design. Fully freestanding or combined with a sauna or a jacuzzi? Our standard outside finish or a personal touch? You hold the cards. 

Product characteristics

Standard or tailor-made?

Our outdoor steam room design is the same as our indoor version, but only more isolated and completely waterproof.
The outside of the steam room is covered with aluminium sheets. We provide a treatment with  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.

Our inside finish is standard black or white.

Our outdoor steam rooms are available in a wide variety of sizes and models, but we are more than happy to make a tailor-made design. Do you prefer to create some additional space by providing a shower or changing room? Less glass or lots of frosted glass doors? We’ll draw up the steam room that makes your heart beat faster.


Cannot wait to start designing and customizing your very own outdoor steam room? Take a look at our brochure and be inspired by our indoor models and infinite options. Would you like some more information or advice? Please, don’t hesitate to contact us for a custom quote. 


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

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.

Super tevreden over de mooie op maat installatie van Thermalux. Prima service en tot in de puntjes verzorgd. Heel tevreden klant. In deze moeilijke Corona tijden niet altijd evident!

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!
