Material Type: Boulder Swirl


Size: 33' Round


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 33' 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.

  • Looks great!
Material Type: Tidal Surge Size: 24' Round
My old cover was about 9 years old and had multiple issues. It had a leak and since it was old it had stretched too much and was coming loose. This is a great replacement for my 24' round pool. Came quicker than expected. Looks awesome and was easy to install. It seems very durable and I have had no issues since installing 3 weeks ago. ... show more

  • Pretty pool liner
Material Type: Boulder Swirl Size: 27' Round
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! ... show more

  • Pool liner
Material Type: Crystal Tile Size: 27' Round
Everybody loves our pool liner. It’s very pretty and it fits perfectly on our 27’ x 54” pool. It was also, half the price, that our local pool stores wanted, for the same exact liner. Very pleased so far.

  • Hole in the liner - not seam
Material Type: Boulder Swirl Size: 27' Round
Installed new liner last week only to discover a puddle outside the pool several hours after the last water truck pulled away. I paid particular attention to how I handled the liner, and even more attention to not stepping on the liner. After researching previous complaints about the warranty and how this company handles it, I choose not to even try for a refund. The hole was about the size of my pinkie, so yes I have a brand new liner that looks nice , with now a nice new patch. Spend the money and buy a better liner from a reputable company. I chose not to drain my $700 worth of hauled in water to cut a sample out of the liner to send to the company and await a decision from them on whether it was caused by them or me . I know how that would turn out ... show more

  • Exactly as expected
Material Type: Boulder Swirl Size: 24' Round
Liner was easy to install. No leaks that we’ve noticed so far and it’s been installed for a week now. Our pool is 54 inches in the center and grades up and the 54” liner worked perfect. The size was perfect. No issues or complaints so far
