With just a few rough-in dimensions, we can precisely manufacture, and promptly ship, a pre-sloped, leak-free shower base that will perfectly fit your shower floor’s design. No need to pay someone to move the drain, or re-frame a wall to fit a pre-molded shower base size. With a PSI custom ShowerBase™, You can save money, time, and get exactly the size, shape and drain location you want.
No integrated drains, messy epoxy mastics, hollow curbs, or additional perimeter flashings are required. A PSI shower pan has a solid-core curb, and it comes factory equipped with a perimeter “leak-protection” flange (No Additional Charge).
We build your custom shower pan to any shape, size and custom drain location. We offer many variations, materials and colors in our custom shower bases. We can provide quick and accurate pricing over the phone in minutes after learning your project specifications.
All products can be built to the customer provided specifications, dimensions, colors. We provide many benefits including:

Hard Core & Leak Proof Shower Bases
PSI products are similar to the nearly indestructible surfboards used by professional surfers. But Better! Starting with the highest density EPS core available, PSI is able to engineer a rock solid shower base. The shower base is factory sloped to the drain, and surfaced with two types of composite fibers embedded in an advanced epoxy resin (View) – thus ensuring strength and surface durability. The flange and curb are fusion welded to the perimeter.
We invite you to visit our Charleston showroom and tour our facility. We also offer free in home estimates for your convenience.

Frequently Asked Questions
We start with a 3-pound high density EPS core and shape the base with a 1/4″ per foot (2%) slope to the drain. In its raw state, the 3-pound EPS is tough; However, both surfaces (top & bottom) are then coated with a proprietary blend of hard coat epoxies and embedded composite fibers that gives the shower base its ultimate durability and strength. Next, the perimeter flange and curb are fusion welded to the sloped core. It is then coated in our elastomeric waterproofing and crack isolation membrane. It is completely waterproof and ready to install when you receive.
The flange is a 1/8″ thick, 5″ high FRP composite material that is designed to rise between the stud wall and the showers backer wall. The flange provides a water barrier to prevent water from exiting the shower during normal use, or in case of a “back-up”. The flange is fusion welded to the perimeter of the shower base’s core. This exclusive feature increases the likelihood that any moisture that was to penetrate the shower wall would exit into the shower base area, and not to the outside of the shower pan. A flange is attached to the perimeter of the shower base’s sloped core where a “curb” or “ramp” is not located. See next FAQ.
The “curb” or “ramp” is sometimes referred to as the threshold. The curb is the perimeter component of a shower pan that you “step over”(curb)or “roll up”(ramp)when entering a shower. Our standard size curb is 3 inches (high) X 3 inches (deep) X (variable length). Our standard size ramp has a 6” “run” (the part that you roll up when entering the shower). The length of a curb or ramp depends on the shower bases individual specifications.
We can customize both the curb or the ramp upon request.
The curb is also where the shower door is placed. We can make the curb as long as you prefer: half curb, whole curb, and double curbs. Ramp options are more limited.
Minimum sizes for curbs is 2 ¾” high, 3” width (for Shower Glass).
Using a 3/4″ U-notched trowel (supplied with all shower bases), spread some modified thin-set into the area that the shower base is to be installed (Important: do not use a “premixed” thin-set. It will not cure properly). Then set the shower base in place, and ensure that it is well embedded in the thin-set. The thin-set takes care of any floor imperfections and is the adhesive that holds the base in place. Make sure to put a level on the base to ensure evenness of the base.
Once that is confirmed, leave the base for 24 hours to allow the thin set to dry. You can then begin the process of putting up your shower walls.
Any quality “polymer modified” thin-set will do just fine. Do not use a premixed thin-set (ie….water already added). A premixed thin-set that comes in a bucket with water already added will not cure properly.
Remember: No premix! Always add your own water!
Different terms for modified thin-set include: modified thin-set, modified thin set with a latex additive, fortified thin-set, polymer modified thin-set, polymer fortified blended thin-set.
The thin-set must meet or exceed ANSI A118.4 and ANSI Al18.11 requirements when mixed with water.
Four most recognized brands:

Each of these companies also sells a rapid set product.
You will need to cut a 6″ hole in the sub-floor. The drain’s “body” will need to recess into the sub-floor 2″.
There are adapters available. We do not sell these adapters. We recommend that you consult with a local plumber, or plumbing wholesaler about this issue. Local codes can vary. The pipe required needs to be 2” thick.
Every shower base is custom. We order the custom core from our partners at KBRS and then begin the fabrication of the base. Standard lead time is anywhere from 2-4 weeks. This may vary slightly due to manufacturing conditions.
It is a solid composite structure manufactured from varying components. Ie….EPS core, FRP Flange, composite fiber…epoxy resins and Corian solid surface.
Options available:
Chrome
(standard), Matte Black*,
White*, Polished Nickle*, Aged Bronze*, Gold*, Brushed Nickel*
*upgrade option
If your sub-floor is structurally sound (no rotting…etc.) and level (very important), then applying thin-set directly to the sub-floor is okay. However, we do not recommend applying thin-set directly to particleboard.
The only requirement is that the drain location needs to be 8” off the studs – front to back and right to left.
This will allow the proper slope to be achieved for drainage purposes.
Linear Drains are not available at this time.
Have a 2” PVC pipe stick up 6” from the subfloor. This will later be cut down flush
After installation to properly connect the drain.
The maximum size for a Custom Corian Shower Base is 96”x65”. For oversized shower bases that need to be shipped, please contact a representative at Palmetto Surfacing to discuss options.
