Fundo Ligno

„The Specialist for Suspended Timber Floors.“

The floor-level shower bases designed for use with timber floors, and with outer edges of only 20 mm. Unlike traditional shower elements, the Fundo Ligno has been adapted to be integrated into a wooden floor covering – without building up further height and without time-consuming levelling measures it fits into its environment perfectly.
The tileable floor units are not only highly practical and reliable, they have opened up a whole new world of design possibilities for wet rooms and bathrooms.

  • Certainty thanks to a uniform predefined slope
  • Entire system is 100% waterproof
  • Simple and safe to work with - tested by those in the trade
