Molds: Shower Pans and Accessories Print


adashower150Gruber is your source for the highest quality Shower Pan molds and other related accessory molds, including Shower Seats, Shower Ramps, Thresholds, Curb Molds and more.
Shower Pans are available in two basic types - dedicated size (standard) single cavity molds, and "Universal" molds.
Universal Molds are large molds that can be used to make any number of castings of different sizes and proportions from a single mold - thus they are an economical, highly versatile option for shops if you don't want to stock a lot of different shower pan molds.
