I purchased this Prime-Line frameless shower door bottom seal to replace the original framed bottom on my shower door, which was over 10 years old. Rather than replacing the entire door, I decided to try this product first, and I am very glad I did. Removing the broken original framed bottom took considerably more time than installing this new seal. It slips onto the glass easily, fits perfectly, and gives the shower door a much more modern, updated appearance. One of my favorite features is that it is virtually invisible, so it doesn't detract from the look of the glass door. I purchased this seal about six months ago and have had no problems with cracking, wear, or deterioration. Despite some reviews mentioning these issues, mine still looks and works like new. Installation was straightforward. I used a box cutter to trim the seal to the correct length and fine sandpaper to smooth the cut edges. Although the bottom of the seal does not quite touch the tile beneath it, I have had no problems with water escaping outside the shower. Another advantage is that the seal can be removed easily when it is time to clean it, making maintenance much simpler. Important tip before ordering: Measure the thickness of your shower door glass carefully. The difference between the 1/4-inch and 3/8-inch versions is significant, and getting the correct size is essential for a proper fit. Overall, this product was an inexpensive and effective way to update my shower door without the expense of replacing the entire door. After six months of trouble-free use, I am extremely pleased with the fit, appearance, and performance. I would definitely recommend it to anyone looking to replace an old or damaged shower door bottom seal.

Fits snug and does the job as long as you measure well and your shower door is level with the floor. This is the second one I've bought and it's not because the first one failed but because my shower door is not perfectly level with the floor and I have to trim the sweeps. I happened to trim a little too much on the first one and the sweep was no longer touching the tile. It still worked fine but not as well as it should and if I don't do something right I'm going to do it again. I'm not sure why one of the pictures of the product shows the sweeps off the tile. If they aren't gently touching and your tiles aren't angled into the shower it will pool up and run outside the door. Putting it on my doors as it came from the package caused it to jam and I had to pull hard to open the door. Once again that's not the products fault. With the new one I measured the distance on both ends of my door and cut the sweeps to match the distance from glass to tile. It's not easy but you need to learn to be handy to problem solve and overcome the annoying things in life. For the people that are getting leaks I'm betting that it's because of one of the following scenarios: 1. The gap under the door is larger than the sweeps. 2. Water is going through the vertical gap between the door and the other glass panels adjacent. 3. Their tiles were installed poorly and water is running out of the shower. 4. They shower like a baby bird in a bird bath and get water all over the door. It's not going to be a 100% water tight seal but that's not what it's supposed to be. It does what it's supposed to do which is keep splashing water from easily seeping and pooling on the outside of the shower door. If you shower like a normal human and your shower head isn't aimed directly at the door you should be good to go and happy with the purchase.

I bought this bottom seal for my frameless shower door and it worked very well. The clear design keeps it looking clean and discreet, while the seal fits securely on the 3/8-inch glass and helps prevent water from getting underneath the door. It was easy to install and made a noticeable difference in keeping water contained inside the shower. The material feels sturdy and well made, and it gives the door a finished look. Overall, a simple but very useful replacement part.

Replacement for glass shower door. Works well, good tight fit, easy to slide onto bottom edge and able cut to size

This fixed our problem almost 100%. We just built a new house and decided to have frameless shower doors because we had seen some in a nice hotel we stayed in and we loved the look. I also loved how there was no u-shaped metal track on the bottom of the shower for the door to sit in, which can turn into a hard to clean place for dirt to collect, not to mention it can be ouchy on your feet if you step on it or stub your toe. However, the shower in the hotel did not have a sweep like this, and after using it, we ended up with quite the puddle of water on the hotel bathroom floor. I figured it was just poor design of the tile ledge that the door hangs over, and if we simply had our builders make sure that the ledge was sloped enough, the water would run down the door and continue down to the drain. However, after our beautiful bathroom was completed and we moved into our house, we quickly discovered that we too were having water escape under the glass door and all over the floor. I Googled the problem and discovered these clear shower sweeps that people were raving about and decided to give it a try. It's not very expensive and it installs simply by sliding into place with no glue or adhesive, so there was really not much risk involved. (The lack of glue also means it is easy to remove for cleaning purposes.) With super fast 2-day shipping, it came, we clipped it on the door, and immediately our problem was solved! We had almost zero water escaping the shower. The remaining escaping water is caused because we also have a slight gap along the side of the shower door where the occasional well aimed drop or two can find its way out, but it is minimal enough that we have not opted to also install an additional h-jamb along the side of the door because the h-jamb will not allow the door to continue to open either into the shower or out into the bathroom space (you have to pick which way you want the door to open, instead of having both options). But, if we decided in the future that those extra escaping drops were overly problematic, then I would not hesitate to install an h-jamb as well (http://smile.amazon.com/Polycarbonate-Jamb-Hard-Degree-Glass/dp/B001G12TZQ/ref=pd_bxgy_60_2?ie=UTF8&refRID=0YWV6MKMT2YTW3EZS2S7). We are very happy. So happy, that we got a second sweep for the downstairs bathroom as well. Although, one word of caution; it appears that how tightly the sweep seals between the bottom of the door and the shower base ledge depends on how exactly hung the door was originally. Our basement sweep fits slightly more snug than our upstairs sweep because the door in the basement was hung just a fraction lower than the upstairs door. This make for a tighter seal, but it also make the door slightly more stubborn to open and close. Perhaps, with wear, the plastic will become less stiff and allow the door to swing more freely.

This has been my go to Brand/Model of replacement shower door seal since we moved into our house in 2019 that required them. I have replaced them at least once a year when they wear out. They have always been great and worked much better than what was on the shower when we moved in. Just received my most recent order. I’m not sure if the manufacturer has changed, or if they have just changed the design to save money. But this is definitely not the same product. The plastic is brittle making it nearly impossible to cut to size without breaking some pieces off. The actual door sweep on the bottom is stiff and a fraction of the length of the one that I took off. This makes it useless as a shower door seal. Just ordered a different brand. Hopefully it will be like the old Prime-Line. Be forewarned. If you have ordered these in the past, you’re not going to get the same quality product that you’ve gotten before.

It was easy to install, had the right dimensions and worked to keep water from leaking. However, it broke within a month of purchase.
