Features
- MEASURE TWICE, BUY ONCE Whether installing for the first time, or replacing an existing liner, the Boulder Swirl 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 27' 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 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 Boulder Swirl 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 20-year limited warranty is included protecting against defects in material and workmanship.

Going on year 3 of liner and have had no issues! Holding its color and not stretching out. Was very hesitant on buying online rather than local pool store, but after 3 years would buy again. Got this to install on a pool we were given. Easy install, will need couple others hands to help as a lot for 2 people. Having the lip to hook over the walls is so much better than the extra being pulled over and trying to keep level. If watch some videos on how to fill once installed will help alot as well!

I purchased this as a replacement for my above-ground pool and it fit perfectly, it was not too bad of an install, with no leaks or issues so far and we have been using it for a couple of months. The lady that did our installation recommended we order online vs. getting at the pool place due to being cheaper, and stated these are the same liners as the pool places have. She was correct, it did save me a few hundred dollars and we are pleased with the liner.

The liner looks great - but the item shipped is not what is advertised on Amazon. 52" wall height ordered, 46" wall height received. This company tried to blame this on our "incorrect installation," but this liner collapsed my above ground pool twice (pool liner height too short>fill pool with water>collapsed top of pool wall both times!). This company's customer service was adamant that it was the right liner for my 52" wall. They claimed it collapsed the pool wall because the sand cove at the bottom wasn't large enough, but even with a very large cove, there is no way for a 46" liner to stretch to 52." The seller has approved a refund, but are making me pay for return shipping (even though they send me the wrong item - I ordered the correct size!). Their return information also states that if the liner is not in new condition, the refund price will be reduced. The liner is used since I tried to install it twice per their instructions and I have no idea how I would be able to get this back into the original box - plus I can't imagine how much it would cost to ship back. It's unfair that I order the correct thing and they sent the wrong thing and now it's my problem. Two local professional pool installers have confirmed that the liner size that they sent was not meant for a 52" wall height. I've always had good luck with Amazon and the rare occasion I've needed to return something. However, this experience has been very disappointing. I would not recommend buying a pool liner from this seller. I bought the correct size liner from a local pool company and it worked like a charm - finally using our pool!

Contracted with some guys to install. They had it in fairly quickly. Looks good in the pool. Some wrinkles, but that’s not the liner’s issue. I’d recommend. The guys said the quality was really good.

I'm giving it 5 stars. Liner was $490 in town. Amazon price was better. It installed with ease. It looks great. Its ok only been installed a few days. So far so good. *Update* Liner seperated at the seam and caused a leak. Seller quickly honored the warranty and sent me a replacement. They were out of stock of the kne I bought so o chose a different design. It looks great. It installed easy and no leaks. I still give the inner 5 stars because the split in the liner could have been from the beating the box took during shipping.
