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. 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 15' x 30 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 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.

  • To small
Material Type: 25 Gauge Color: Mosaic Diamond
This pool liner was installed on Monday on a 15 x 30 oval pool and when about 1 foot of water was in the pool it came loose on the left side of the pool and could not stretch back over the pool. The man who was installing the liner measured it and said it did not measure quite 30 ft. He did not take pictures and I was so upset I did not think to take a picture. He pumped out all the water he could and stretched the liner back over where it came off in case it rained and said if it rained and he didn't do that then water would get behind the liner. I ordered another liner this time 70 inch wall height because he said if it was deeper he could make it work. I paid over $600 for that liner and paid him $700 for all the work he did and now it will cost me a lot more for the liner I just ordered and will have to pay him again for the next one. I cannot afford both liners and to pay him twice. Please help me with this problem. Loretta Tigue ... show more

  • Looks good, fit great!
Material Type: 25 Gauge Color: Mosaic Diamond
So far so good, packaged well, the print under the diamonds goes all the way across the bottom as well, just fyi. We had to cut the top off since we have a beaded liner, it was easily done. We let it warm up in the sun, folded into a log, then into 1/3 rds. We use a vacuum taped to the return water hole to pull the liner inward several times, then we adjusted the wrinkles by carefully pulling the liner in the appropriate direction from outside of the pool. This helped reduce the work once water was added (note: you have to tape over your square cut out for the return). We had a few small wrinkles, not to bad for amateurs. We bought a 15 x 30 with 52 inch walls. We also marked the centers at each end of the ovals on the backside with a marker, so when we were stretching it out we knew where to place it, this was just an educated guess of course but helpful none the less. Wish we had a round pool! ... show more

  • Fades like crazy
Material Type: 25 Gauge Color: Mosaic Diamond
Purchased in May of 2017 and Loved it ! Beautiful color great fit and easy to install . But here we are in 2020 and each year it has faded so now the bottom of the pool has barely any color. I am super disappointed . Our first liner was 12 years old and looked better when we took it out than this one does starting it’s fourth summer. Don’t bother to purchase , it won’t last Update…. 2023 need to purchase a new liner , besides the color fade (completely faded) it has started to break down. Didn’t finish out last summer , it was gross! ... show more
