Thermalux was founded in 2009 by Mario Mertens and has grown into a proud family business with Belgian roots. With his daughter and wife on board, we have further strengthened our passion for high-quality saunas and steam cabins. Our products are entirely designed and manufactured with the finest materials in Belgium and proudly bear the “Made in Belgium” label.

Initially, we focused exclusively on direct sales to end customers, even far beyond Europe. However, in 2021, we expanded our focus to the B2B market. While we still supply individuals directly from our factory, we now also collaborate with an international network of distributors and partners to further enhance the growth and capacity of our manufacturing company.
