Collapsible Water Dam Threshold For Roll-in Showers

A rubberized barrier that is used to contain water within a roll in shower. Placed along the entrance, a wheeled shower commode compresses the barrier as it passes over. Afterwards, the barrier resumes its original shape and prevents water from exiting the shower.


  • inexpensive
  • easy to install
  • prevents slips as it keeps water within the shower and keeps nearby flooring dry
  • highly effective when combined with a shower curtain
  • easily compresses to allow wheeled commodes to enter the shower


  • not effective for keeping splashing from exiting the shower; one needs to use a shower curtain in combination with this device.
