About Kotyshower
Our Story in Brief
Our backerboard technology was first developed at Dow Chemical, where engineers sought a lighter, stronger alternative to traditional cement boards. The breakthrough led to products later expanded by National Gypsum and adopted throughout the building industry. Today, under the KotyShower brand, that same innovation has grown into a complete shower system — from pans to backerboards — featuring our signature 5-inch waterproofing overlap for faster, more reliable installations.
