Fundo Ligno

„The Specialist for Suspended Timber Floors.“

Product information

The floor-level shower bases designed for use with timber floors, and with outer edges of only 3/4" (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
