Product information
The shower element with linear drainage especially for suspended timber floors.The Fundo RioLigno is a complement to the Fundo Ligno shower element that has been established on the market for many years. It offers a flush-to-floor solution with elegant linear drainage for timber floors. With it’s outer edge of just 25 mm, the Fundo RioLigno shower element fits wonderfully into the existing wooden surface layer without cutting into floor joists or building up further height.
The new wedi Fundo channel drain substructure element was especially designed for use with the Fundo RioLigno. The pre-formed foam element guarantees reliable support and accurate aligning of the drain underneath the shower element eliminating the time consuming building and filling with mortar/screed thus speeds up the installation even further. An additional bonus: Fundo RioLigno is 100 % compatible with wedi channel drains and covers as well as with slope profiles and preformed sloped lip-end sealing tapes from wedi.
