Shower Pan Molds

Marshall-Gruber is your source for the highest quality Shower Pan molds and other related accessory molds, including Shower Seats, Shower Ramps, Thresholds, Shelves, Curb Molds, Soap Dishes and more.

Shower Pans are available in two basic types - dedicated size (standard) single cavity molds, and very cost-efficient "Universal" Shower Pan 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.

1050 Universal Shower 325Gives you great versatility and value in a single mold!

Universal Shower Pan molds simply make economic sense - since you can produce any number of different size and shape shower pan castings from a single "universal" mold. If size is an issue, you can order a smaller overall mold size (see chart below for available sizes). Universal Shower Pans can be cast at full size (as shown below), or smaller. Determine what size shower pan you need, and define that around the drain located where you need it. All 1050 Universal Shower Pans have center drains and a minimum drain slope of 1/4" per foot of horizontal distance. All 1050 Universal Shower Pans have center drains and a minimum drain slope of 1/4” per foot of horizontal distance. Surface is textured.
