39in Shower Threshold Water Dam - Self-Adhesive Silicone Barrier | Collapsible Design Helps Contain Water in Walk-In Showers, Tubs and Wet Areas. Flexible Profile Installs Without Drilling

Contain water at the shower threshold: The 39-inch shower water dam creates a flexible barrier along the shower threshold to help contain water within the wet area. Suitable for walk-in showers, shower floors, bathtubs and other areas where water needs to be kept within a defined space
Collapsible, flexible passage design: The soft silicone profile compresses when stepped on or rolled over, then returns to its original shape after pressure is released. The low-profile design provides a smoother transition for everyday foot traffic, wheelchairs and walkers
Hollow triangle structure: The hollow triangular profile provides room for the dam to flex and compress, helping it conform to minor surface variations such as tile joints and grout lines. The flexible strip can also follow gentle curves and corners for a more adaptable fit
Peel, press & seal: The self-adhesive backing makes installation simple without drilling. Apply to a clean, dry, smooth surface such as tile, stone, glass or acrylic, then press firmly along the entire strip. For a more secure edge seal, a suitable waterproof sealant can be applied along the edges after installation, particularly on uneven surfaces or areas with frequent water exposure. For removal or repositioning, gently warm the adhesive with a hair dryer to soften the bond before lifting
