"The wedi wet room system in a box."

Product information

All products needed to build a wedi Fundo Primo point drain shower are included and provide a single manufacturer warranty. Safe transportation in one box, easy estimating of product quantities needed. The shower floor units feature a strong and pre-sloped surface which can be tiled over immediately whether you choose mosaic size or large format tile. Pre-sloped extension panels are available so that virtually no limit exists for making any size or shape for custom shower designs happen. Naturally, Fundo Primo is insulating keeping surfaces warmer. Especially when compared to traditional mortar bed installations or other currently known methods for building showers such as those including use of sheet – or liquid waterproofing membranes used in an attempt to manage water exposure – wedi Fundo Primo‘s simplicity and high performance shows. The most unique advantage, however, is the complete and natural core waterproofness of the wedi product and its completeness and range of components that will form an entire assembly system with Fundo Primo engineered to fit and last. This is a true system with full warranty coverage.

  • Safe transport in a box
  • Perfectly matched
  • Complete peace of mind for installers and end users
