The Wedi Fundo Ligno Shower Kit contains all products needed to build a Wedi shower. No more guesswork, all materials, and quantities are estimated for you. The Ligno Kit is internally waterproof due to its Wedi XPS foam’s closed cell structure and naturally protect against mold or mildew like every Wedi XPS foam-based product. The Fundo Ligno Kit adds speed, safety, and consistency to your installation: Measure, possibly cut, thinset to subfloor, connect drain – done. The most unique advantage, however, is the complete and natural core waterproofness of the Wedi product and it’s completeness and range of components that will form an entire assembly system with the Fundo Ligno Kit engineered to fit and last. A true system with full warranty coverage.
