Collapsible Shower Water Dam (Shower Water Retainer) Kit

$45.00 USD$68.00 USD

Our Collapsible Water Dam or Shower Water Retainer Kit controls your shower curtain and water from escaping out of your roll-in or barrier-free shower stall. The water dam base is 1.0 inches wide and stands 1.25 inches but collapses to just 3/8 inches when stepped on or rolled over, returning to its original shape thereafter.

This kit includes everything you need to install. It is available with or with out the end-caps. End caps are not needed if the walls of your shower unit are at right angle to the shower pan.

In these situation most customers use a friction fit by placing the end of the water dam directly against the shower wall. Some customer if needed will add some silicon caulking between the water dam ends and the shower wall.

End caps are used where there is a slight curve between the bottom of the shower pan base and the side walls. The use of the end caps provides a more professional finish look.

Trusted in Homes and Hospitals

Health workers appreciate the extra safety provided by our shower water retainer. Safety is increased by retaining water in the shower areas to keep the rest of the area dry preventing slips. Roll in, barrier free, curbless shower stalls all can benefit from using our collapsible shower water retainer dam.

Easy to Install

To install the retainer dam simply trim the strip to fit, remove the backing from the self adhesive strips, and apply in place directly below the shower curtain rod. It can be cut to your measurements or shipped in a bulk roll for multiple jobs.

Additional Solutions

To ensure the water dam is able to catch your shower curtain you can use our extra long shower rings to easily lower your shower curtain to the proper height. Also, the shower curtain kits seals the curtain edges to either side of your accessible shower providing even greater curtain control.
