Fundo Riolito

wedi’s Fundo Riolito linear drain shower base system features the only fully sealed and factory integrated waterproof drain assembly available in the market of customizable shower floor systems with linear drainage. Fundo Riolito is internally waterproof due to its wedi XPS foam‘s closed cell structure, and naturally protects against mold or mildew like every wedi XPS foam based product.

 It is fast and clean to cut to fit custom designs while prefabrication reduces installation time significantly. The base features a strong and pre-sloped surface, allowing for tiling immediately whether you choose mosaic or large format tiles. Pre-sloped extension panels are available so that no limit exists for creating any size or shape for custom shower designs. Fundo Riolito is insulating, creating a thermal barrier that can prevent cold from transferring through the tiled surface, and make floor heating systems more efficient. It also has outstanding moisture and water exposure control compared to traditional mortar bed installations or other currently known methods for building showers, including the use of sheet or liquid waterproofing membranes which can be very thin and vulnerable, or they may offer water absorption into thin-set bonded seam areas.

 Fundo Riolito is available in two design options: wedi Fundo Riolito and Riolito Modular. 

wedi Fundo Riolito is available in multiple sizes and feature a level shower base perimeter provided by a 4-way slope. These models provide for a perfect installation when recessing the base into a subfloor where a flush to the floor entry is required but they can also be installed with a curb.

 The second option is Fundo Riolito Modular which includes a model featuring a true one- way slope towards the linear drain. It comes in two modular elements which are joined during the installation: Line Module and Extension Module.

 All Riolito shower base models are available with linear drain cover options including finished and tileable options. The covers can be adjusted in height to match your tile or stone. The system comes with helpful accessories such as spacers which are temporarily used in the drain channel to allow for a perfect finish of tile edges with drain trench.
