A modern outdoor sauna, with a 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.

For those who really want to take relaxing to another level, we designed an outdoor sauna with a shower combination. We provide a small passage to fully integrate the shower or we build a shower room adjoining the sauna, allowing you to shower in complete privacy. Fun fact: your shower and sauna heat up at the same time, so you can start off your spa treatment with a preheated shower.

Product characteristics

Our outdoor sauna design is the same as our indoor version, but only more isolated and completely waterproof.
The outside of the sauna 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.

 We integrate the shower through a small passage that you can also customize with some additional glass. For the occasion, we made custom designed rain showers.

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. 


Cannot wait to start designing and customizing your very own outdoor sauna with shower? 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.

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.

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.

reeds 2 maanden een PUU2 met infrarood en met houtkachel ; top product en top service ; prachtig design en plaats voor 6 zittenden (echt leuk) ; donkerglas aan te raden als je buren hebt !!

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.

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!
