Review: Great product - This product worked really well. We needed something to make the lip of our walk in shower higher after removing the shower doors. We have absolutely no water that spills out and it has made cleaning so much easier. This product was easy to use and stayed in place.
Review: A fully-functional and comprehensive package that works beautifully! - I bought 5 ft. black water dam barrier package which comes with 5 ft. silicone water dam barrier with adhesive tape (exactly as shown in the picture, very heavy in weight and yet fairly flexible to bend to create any shape water boundary), a utility knife, a marking pen, 2 caulking tools (caulking finishing tool to smoothen caulk, caulking scraper to remove excess hardened caulk), a clear waterproof caulk/glue tube with nozzle, and a pair of plastic gloves. For whatever unknown reason, my top-hung sliding shower doors had an existing water dam barrier on the outside bottom edge only. They did not have one on the inside bottom edge which somestimes caused the sliding doors to come off the track. After doing an extensive research and trying a few alternates to remedy the situation, I finally came across this product. To be honest, I did not even know what exactly to search for as I did not know the name. Thanks to ChatGPT for a huge help to reveal the product name "Water Dam Barrier"! Once I figured out what exactly to search for, I purchased this particular package in late October 2025 to use it on the inside bottom edge of my sliding shower doors as it meets the required color, length, and height. The water dam barrier is very easy and quick to install. Simply prepare surface, cut it to length using the utility knife, bend into the desired shape, remove red adhesive backing little at a time, and press it firmly for adhesive tape to stick to the surface. I also applied the waterproof glue and shaped it using the supplied tools. All together, it took less than 15 minutes to finish the job, the longest time was to prepare the surface. I left it without using shower for 2+ days to ensure the strongest adhesion. After a week of using the shower, it still remained glued and hard as rock. As for it not being able to maintain the adhesion (as per numerous other reviews), I do not know yet. I will update this review after using the shower for a couple of months. My sliding shower doors finally remain aligned to the tracks. P.S. I have not been paid to write this review, however, I feel very ecstatic to having finally found this comprehensive package that worked so beautifully!
