Features

  • MEASURE TWICE, BUY ONCE Whether installing for the first time, or replacing an existing liner, the Swirl Bottom 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.
  • NO TROUBLE TO INSTALL - Overlap liners are draped over the walls of the pool during the installation process. Once the bottom seam is even near the cove, the liner is ready to be secured. This material is held in place through the use of coping strips prior to putting the top rails back onto the pool. Bead receivers are not needed for this type of liner. The liner is made to work with pools which have a flat bottom and wall heights of 48 or 52. ***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 aboveground pool will surely become the place to be during those hot summer days. Stay cool in more ways than one with the Swirl Bottom 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.

  • Nice liner, fingers crossed!
Material Type: 25 Gauge Size: 24' Round
This is our third liner with this pool but also 3rd set up. 25 mil bottom seems nice and thick. I accidentally ordered a 24' & it should've been 21' but it's unfolded and installed so it's too late. Fingers crossed this one holds up better. *if you're counting on the gaskets mine were missing from the box. *I'll update if I have problems. ... show more

  • great product/value
Material Type: 25 Gauge Size: 18' Round
A good quality liner. Arrived quickly and in good condition. I did have to do a little research for more information on the actual installation. I went back to my original instructions for installing the pool as they don't give you enough information with the cover. That could be because of so many different styles of pools. There are many good hints and tricks though in my original pool installation instructions that were key to a successful installation. Don't be quick about it or you will regret some mistakes. ... show more

  • Great liner including skimmer gaskets but short a gasket.
Material Type: 25 Gauge Size: 24' Round
I really like this liner and had no problem installing it. It heated up in the sun nicely. I used clothes pins to keep it on the wall and as I filled the pool I kept walking around releasing the clothes pins allowing the liner to set in place. However, the gasket kit for the skimmer that came with it only had gaskets for between the front plate and liner and between the liner and wall but no gasket for the skimmer outside the wall and instructions said nothing about another gasket needed there. Well guess what I have water running down the outside of my wall and now I will have to drain the water down below the skimmer so I can take the skimmer back off and add a gasket to the outside. ... show more

  • As advertised
Material Type: 25 Gauge Size: 15' x 25' Oval
This liner works really well. The instructions are a little hard to understand but the important thing is that there are 2 lines that run from end to end thru the center of the pool liner. Your installation will go much easier if you get those two lines parallel to the sides of the pool before you start trying to attach to the walls. ... show more

I bought this to replace or 18 x 52 pool that was less than a year old but needed to be moved. It does not fit and has bubbles everywhere. I wrote the company but the never made good on sending another one to replace it or a refund. I did have professional installers and they said they have never seen one this bad before. This company does not stand behind their product. DO NOT WASTE YOUR MONEY worst liner ever ... show more

  • Beautiful liner
Material Type: 25 Gauge Size: 18' Round
Fits perfectly..It is a two person job to put in an above ground liner. Just make sure it's a warm day so the liner is soft. We started with the liner in the pool.started unrolling it enough so we could step over on it then stared to hang around the edges of the pool wall using clothes pins.As it fills loosen the pins as it does stretch . ... show more
