The new Schlüter-KERDI-LINE-VARIO is a variable system for linear water drainage in floor-level shower tray construction. The system consists of drainage profiles in a modern design, which are individually cut and installed in a trough with an extra-flat outlet canister. The KERDI sleeve, pre-assembled to the gutter, guarantees a watertight delivery of the waterproofing to the drain. In addition, the outlet of the canister is 360° rotatable, which ensures greater convenience during the installation process.
