Features
- MEASURE TWICE, BUY ONCE Whether installing for the first time, or replacing an existing liner, the Laguna pattern offers durability while not breaking the bank. Be sure to check the measurements of your swimming pool to assure the correct size is purchased. Pool height is determined by measuring the outside wall from the ground to underneath the top rail. Oval pool size is determined by measuring from the center point across the longest and widest ends.
- INSTALL IN A SNAP OR A HOOK - This 18' x 33 oval unibead style liner works with pools with flat-bottoms measuring 52". For an overlap style pool, simply open up the j-hook portion and slip this over the pool wall. For beaded style pools, use the standard bead after removing the j-hook portion along the score or groove mark. This will leave only the standard bead which is inserted into the bead receiver opening. ***Will not work with Intex or Pop-Up pools***
- STAY COOL IN THE POOL Enjoy the warm weather while spending quality time with family and friends. Your backyard pool will surely become the place to be during those hot summer days. Stay cool in more ways than one with the Laguna liner.
- HIGH QUALITY MATERIAL - Swim carefree knowing your liner can tough it out through abrasion, chemicals and UV fading thanks to the use of Lamiclear technology. The layers are made of an acrylic top coat, a UV resistant print layer, and a 100% virgin vinyl base. This material is then welded and cut for a flawless fit and finish. A 25-year limited warranty is included protecting against defects in material and workmanship.

Smartline liners are supposed to be really good, but... The first one we ordered had a little cut in the bead section that I was concerned about. The second one had the same cut, just not as big. I'm not sure if that will be an issue or not. My biggest complaint is with the seams. They aren't properly glued down. In some places, it lifts up which can allow debris to get under it. In others, it was twisted and glued down so you see white areas along the seam. Thought I had pics of the seam issues but I guess not. Just very sloppy. Love the look of the liner though and it's a good, thick liner. So, we got the replacement liner but couldn't find anyone to install it so we installed it ourselves. I wouldn't recommend it. Especially for two nearly 60-year-olds and an 18'x33' liner. We didn't have a choice though. Long story short, we ended up buying ANOTHER liner. This year, we found someone to install it. We got a different pattern and love it! It doesn't have the fancy border, but that is part of the reason we got it. Over 13 years in Texas heat, the pool has settle a bit in more places than others and a border makes it more noticeable - although you would really have to be looking for it to notice. It's really a great-looking liner though. Anyway, I love the brightness of the new one. The installer also decided to go with the j-hook rather than the bead. We figured if we ever have to change it again, we'll just take the deck and pool down. This last one had none of the issues we had with the others and it looks great! Ignore the deck in the photo - we're still putting it back together and refreshening it.

We needed a new liner after 10 plus years due to some holes in the pool and leaking. This liner was installed by my husband and daughter and it worked out so well. Liner was installed perfectly thanks to hubby and daughter. It's very pretty and I hope we get many years out of it!

I meticulously put in the liner and filled the pool up with 15,000 gallons of water. Unfortunately, there is a rip in the seam on the very bottom, and the entire pool drained out overnight. However, the customer support shipped a replacement liner and this one worked perfectly. I was impressed with their support efforts.

I’ve never personally input a liner or opened our pool before- my father use to do all of this. After well over 5 years of not using our pool and not having been closed during this whole time, the liner was trash and needed to be replaced. I had no idea how important buying the right liner was until I began doing research and searching for the right size. After reading the reviews on this product/brand and comparing it to others I decided this was the liner I would go with and was happy with my purchase when I received it. It was boxed well and there was no damage done to the product! It unfolded easily and installed as planned! After instillation there was a little bit of extra material because it was hotter than normal when we installed, which was no big deal in the end after all wrinkles came out and the liner settled. We absolutely love the design as well. The pool is now filling up and I’ve noticed no issues with the liner ripping due to pressure or coming away from the side like I had read other products purchased from different companies had done. I would absolutely spend the money and purchase from this company again.

Really easy to install. This fitted perfect on our 18 by 33 oval Pool. Our pool needed an overlap liner and this liner did the job! Only thing I cannot comment is on durability as we just installed it but the material is seemed good.
