Universal Shower Pans and Accessories

Gruber offers a great selection of Universal Shower Pans - depending on the size you prefer. We also provide Universal Drain Collars, Universal Shower Seats, Ramps, Thresholds and more to complete your Universal Mold purchase.


Gives 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.

Universal Shower Pan Ramps

Used with and compliments select Gruber Universal Shower Pan Molds

These universal shower pan ramps are designed for use by physically impaired or handicapped persons needing easy, safe entrance to a shower.

The combination of a universal shower pan and universal shower pan ramps shown here offer a versatile combination compared to the 1052 "Accessibility" line of shower pans that include an integral ramp - since the universal shower pan/ramp combination offers the option of creating different sized shower pans from a single mold pair.

Gruber Shower Seat Molds

These Shower Seat Molds are intended for use with Shower Installations, but may have other uses as well. Bathroom seats offer bathers additional comfort, and are particularly valuable for the physically impaired, elderly and others.

Universal Drain Collar Designed for a Perfect Fit!


The drain boss on Gruber’s shower pans was designed to fit the standard drain.  The problem for manufacturers comes in custom situations such as when working with our Universal Shower Pan Mold. In this instance, a shower bladder must be used to meet building codes. The rubber bladder is placed into the shower opening before the shower base is installed and has its own drain fitting. This fitting cannot be replaced with a standard fitting and sticks up in the shower, trapping water in its base.

Gruber Systems has developed an easy solution that makes this drain fit... just add our new flexible drain collar over the existing drain boss before casting. Fit the collar in place, run a radius around the perimeter of the collar, then gelcoat as usual and cast the shower pan.  The collar creates a drain with a slightly larger diameter and a greater depth which allows the deeper and thicker drain bladder to fit perfectly.
