Collapsible Water Dam - Round End Caps



 The Collapsible Dams are designed to prevent dangerous and costly water spillage in the curbless shower stall. Controlling water spillage will reduce your home or facility's potential liability and maintenance.The proper installation of the dam must begin with determining your shower stall's corner design.The dams are available for modular showers, which have the rounded corners.

The dams are also available for tile showers or shower pans with square corners.

Each of these style shower stalls requires different measurement and end caps. Below is an overview of the proper installation of a Collapsible Dam in the Modular Shower with its rounded style end cap. Here is an overview of installing the dam in a tile shower or where the square style end caps would be required. 



Before You Start:

Determine if you have the proper radius or rounded end cap for your shower. These caps will create a proper fit and finish. They will also help in keeping the shower’s curtain within the dam's barrier.

Incorporating an adequately measured Weighted Shower Curtain will provide the most complete and effective water control solution.

Ensure you have the correct length of the dam for your shower’s opening. Typically for radius corners, you will need to purchase 6" ( 3" on either side) more than the shower's opening to cover the transition effectively. 

(Custom length water dams are available)

Special Note: 1.5” wide flat surface is necessary for proper mounting.

Determine where you will be mounting the Collapsible Water Dam. See if your fiberglass-reinforced shower has a small molded ridge or “water runoff assist” design. This ridge should be on the floor roughly 1-3” from the front entry edge of your shower unit. The inside of the edge of the dam should rest on the crown of the ridge allowing the water to run off properly. Use this ridge as your guide to mounting the collapsible barrier parallel to this ridge.

If your shower does not have the water run-off style design ridge, you must then decide the proper location for installation.

Tools & Materials Required:

  • Utility Knife
  • Tape measure
  • Straight edge
  • Clear or white silicone adhesive caulk
  • Masking tape
  • Rubbing alcohol
  • Bucket of water
  • Clean rags



1. Clean the threshold’s surface of all soap scum and debris using regular bath cleanser. Then, chemically clean the threshold’s surface with rubbing alcohol

2. Double check the required length for your Collapsible Water Dam by estimating the vertical rise necessary in the corner’s transition. Make sure that there is enough Water Dam to make this rise on either end.

3. Measure and mark the center point of the shower

4. Measure and make the center point of the Collapsible Water Dam’s strip

5. Turn over the Water Dam and cut on the orange peel of strip at the halfway mark. Peel of a small portion (roughly 4”) of the orange strip in one direction to expose the adhesive.

6. Line up the water dam with the pre-determined halfway mark or molded ridge crown of the shower starting at the halfway mark. Press on and stick the 4” strip of exposed adhesive. Pull and stretch the water dam and align before removing the remainder of the orange peel of strip. Press firmly into place

7. Peel, stretch, aline and pull the remaining half of the Water Dam to the wall. Press firmly into place

8. Push in the male end of the end cap into the water dam. Stick the end cap to the Water Dam with clear or white adhesive caulk and wipe clean.

9. Use masking tape to temporarily hold the Water Dam’s end cap in place until the caulk has dried.

Now your Modular shower has a long-lasting, easy to clean, bacterial and stain resistant barrier.
