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. Round pool size is determined by measuring from the center point wall to wall in order to obtain the diameter.
- INSTALL IN A SNAP OR A HOOK - This 18' round 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 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.
- UNIVERSAL GASKET SET - The included kit is for the pools skimmer and return. This skimmer gasket will work with either standard sized skimmers or widemouth versions. These pieces will help prevent corrosion of the pool wall and should be replaced each time a new liner is installed as they become dry over time which could cause leaks.

I installed this liner in July of this year, and it looks amazing. Much better than the original liner that came with my pool. The material is thick and seems to be of good quality. Re-lining an above ground pool is not for the faint of heart- It took me a week to pump my pool down and prep the ground, but this liner makes my finished project look like it was professionally installed. I hope to get 20 years out of this one like I did my last pool liner. This material in this one seems to be heavier than the original so I'm optimistic about the longevity of this product.

Material Type: 25 Gauge

Pool specs: 21ft x 52in above ground round in shape. (Distance from bottom rail to bead receiver is 50 inches) The liner looks greats, seems durable, and thickness was as advertised. I installed this by myself and it was not that difficult to do at all. This is a beaded liner and everything went into place easily. I did not notice any issues with the quality. The liner itself is very nice looking. Shipped in a compact box and arrived quickly. Value: For the price you can’t really go wrong. This liner was a bit cheaper in price than the others I was looking at. Performance: it’s been about a month with no issues. Seems to be holding water just fine. Looks great and was easier to install than expected. Time will tell how it holds up but so far as a one month review I’m extremely pleased with this pool liner and would purchase again in the future.

Pool liner is exactly as described fit well in Bristol 18x 33 ft pool. J hook made installing way easier then the overlap liner. Would buy again. Liner appears thick just installed not sure on how long it will last but pool liners are unpredictable and really depend on how well installed.

My husband and I are in our 70's and we were able to install this replacement liner ourselves. I think it looks better than the original professionally installed liner.

We found a hole in our old liner and ordered this one. Having never replaced on before we didn’t know what we were in for. It really wasn’t bad honestly! We cut the old one into sections to remove. Removed the top railing one 2-3 sections at a time and the old liner top edge. Replaced the old with the new as we went around the pool and recapped it. Followed the directions and evened it all out and filled as directed. Everything is working great and it fits our pool better than the original!
