An indoor sauna with a modern and contemporary touch. Thermalux redefines the concept of home wellness by giving it a true upgrade. Focussing on the user experience and relaxation.

Our saunas are designed so that they can either be built in or be freestanding. The choice is yours; a standard model or a custom-made version that’s completely designed to fully integrate with your interior.

Product characteristics

Standard or tailor-made?

Our indoor saunas are made from the best and most qualitative and innovative materials. 

The outside is covered in aluminum, where you have the option to either go for an inox look or choose a timeless black or white colour, with a shiny or mat finish. The front is equipped with a modern and sophisticated glass window. 

You can also choose to have our indoor sauna built in without any outer surface and finish it with your favourite material. That way, you can really create a streamlined look that incorporates the rest of your interior. 

The inside is covered with thermo ayous to create a soft and elegant design. To truly perfect this look, we place two floating benches that make for a spacious and luxurious place to relax. The interior finish is standard black or white, but we allow you the freedom to browse all RAL colours.


Our indoor saunas are available in several sizes and versions. Do you prefer a tailor-made sauna?

We are happy to draw you a custom-made design. A more compact version that perfectly fits your space, a larger glass front or a closed bench instead of a floating one. We build the sauna you need. 


Cannot wait to start designing and customizing your very own indoor sauna? 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.

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!

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.

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!

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.
