Twinline 2

The one and only!

The Twinline shower-tub combines the practical with the pleasant. Shower and bath in one. The impulse was that more is showered than bathed. And that there is often no room in the bathroom for shower and bath. This made many bathrooms into sparse, pleasure-free places. Until the Twinline came. This innovation proved that comfort and small space are not contradictory. We have packed the combination of shower and bath into a compact and affordable product, and in the process opened up a whole new market. Now in its third product generation and countless design awards and imitations later, the Twinline remains the best.


So what is behind the success of our product innovations, such as the Twinline? What is certain is that strong ideas do not simply emerge in CAD programs, nor can they be filtered out of countless customer surveys. It's all about thinking far ahead and digging deep to develop the more attractive, better product experience.


It is by no means easy if you don't want to be among the 70% of so-called product innovations that don't survive their first year on the market. We always manage to do this anew through intuition, empathy and experience. This is how we recognise the potential of ideas that are still delicate at the beginning and develop them into a great success.

"The Twinline is the best-selling shower tub in Europe."
