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 54". 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 25-year limited warranty is included protecting against defects in material and workmanship.

The media could not be loaded. Superior quality to other liners I’ve had. Colors are nice and vibrant.

We installed this liner into our 27' x 54" pool. We did also purchase the floor padding and the wall insulation. This was our first time installing a pool liner. It was easier than we thought! It took us about 2 hours or so to have it installed and filling. It helps to have people on the outside of the pool to attach the top rails as you go along with snapping the liner over the top edge of the pool. We had our son doing that as we were inside the pool putting the liner up. Wasn't as hard as I thought it was going to be. Once it was up, we did attach a shop vac to the water return and that was amazing as it snugged the liner against the wall of the pool so we could work out the wrinkles before putting the water in. We purchased the padding for the bottom of the pool and the insulation for the pool walls. These were definitely worth the money. Easy to install and helped the liner go in so nicely. No wrinkles! Hoping this lasts for years to come!

It’s been up a week and is good. The liner is thick and looks great. Only issue was there were no lines on the back of liner showing center. Took a few try’s to get centered in right spot

If I could give this liner zero stars I would. The liner was riddled with holes all so tiny we didn't even see them until after it easy installed and the pool leaked. We spent weeks trying to find the leak. The holes were all about 9 inches from the bottom of the pool and all the way around the perimeter of the pool. Customer service was terrible. They said the holes were caused by us and that it would not be covered under warranty. They offered to send a patch kit for the 60 plus holes that we were able to find. Our pool drained entirely in less than two weeks thanks to these holes.

I was so hesitant to buy a liner on Amazon but I took the plunge and prayed we could do it ourselves to save 2000 bucks. We have a beaded liner and this is the first time we had ever replaced it (and first time for us period). We watched 4 or 5 YouTube videos and just went for it. It wasn't bad at all. The liner popped right in and fit just like a glove. It seems to be very sturdy and good quality. I really wish they would have had more options as far as pattern went (I really wanted the under water sealife scene) but that's all I can complain about. It was fast shipping, well packaged. And really not as heavy as ai was anticipating! I would DEFINITELY recommend!

This was the first pool liner I installed myself. The liner itself fits good and installs easy enough. The prep work, not so much. I'm totally satisfied with the outcome. The pool itself is 16 years old and this liner will hopefully make it last for another few years. I don't have a clue how long it will last, hence the 4 star rating instead of 5 stars. That said, the package came as promised and in good shape. I was especially happy that the liner didn't have any holes or ripped seams as some have reported. Returning something like this would be a nightmare.
