ISH 2025 was a complete success for us!

With a very good visitor turnout and keen interest in our products, we were able to hold many valuable discussions – both with long-standing customers and numerous new prospects.

A special highlight was our exhibition booth, which attracted considerable attention with its impressive design and the "sea of ​​parts" on the ceiling.

🔹 Visitor favorites:

Our hot tub was the center of attention

Our outdoor spas also delighted visitors

The Koller Milk, which amazed visitors in the outdoor spa and hot tub and was frequently demonstrated, was a real eye-catcher

Our new innovations, the Glass Touch Switch and the Walk-in Bathtub, received a very positive response

Our powerful pumps and the wide variety of whirlpool components also attracted considerable interest

We would like to thank all visitors, partners, and customers for the valuable exchange and look forward to the next exciting projects!
