Material and design: Shower threshold dam made from silicone rubber that is environmentally friendly, soft and foldable. The flexible design lets you form all sorts of shapes as needed. Versatile and adjustable: Soft and bendable when stepped on, it rebounds to its original shape instantly. You can easily create curved shapes and cut the length to suit your space. Flexible enough for a wide range of curved thresholds. Easy installation with sealant: Very easy to install. The threshold dam has a sticky backing; tear off the protective layer to reveal the adhesive, then apply the included sealant on both sides of the dam to create a strong waterproof seal. Note: glue is not included. Easy care: Simple to clean with a damp cloth. Key benefits for you: Provides a reliable water barrier at the shower entrance, fits irregular or curved thresholds thanks to its flexible silicone, and can be sized to your space with a simple cut. The combination of adhesive backing and included sealant ensures a waterproof seal without messy glue. Use scenarios: 1) Standard home shower with a fixed threshold: cut to length and install along the base to prevent water spilling onto the bathroom floor. 2) Curved or irregular shower bases: bend and shape the dam to follow nonlinear edges, then seal for a leakproof barrier. 3) Bathroom renovations or rentals: quick, tool upgrade to improve waterproofing by simply trimming, applying adhesive, and sealing with the included sealant.
