  • 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.
  • PRETTY PLEASING PATTERN - Your swimming pool will have a nearly bottomless appearance with the rolling water along the floor of this Swirl Bottom pattern liner. The North American cut material is hand-folded to prevent permanent creasing and excess wrinkling. Before installing, lay the liner out in the sun for a minimum of one hour to warm up the vinyl ensuring it is able to stretch when adding water. The best temperatures to install would be between 70-80 degrees.
  • 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 pool’s 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.

Liner Knowledge

Comparison of Smart-Line Liner against other brands shows that liner does not fade do you sunlight

SmartLine liners hold up better than many alternatives thanks to an acrylic coated layer on top of its virgin vinyl. Prevent liner fading due to chemicals or UV rays and keep the vibrant colors of your swimming pool liner.

Bead-Receiver with a circle and cross symbol

Overlap style is made to drape over the pool wall and is held in place with coping strips. This installation type does not require the presence of a bead receiver.

Thermometer showing off the temperature gauge in both Fahrenheit and Celsius

Be sure your environment is suitable before installation! Air temperature should be at least 70-degrees when installing.

A stop-watch with a one-minute clock face plus a sun

SmartLine liners come folded to prevent creasing. Lay out in the sun for at least 1-hour prior to installing to ensure the material is able to stretch when adding water.

Don't Forget To Protect Your Liner!

SmartLine pool liners are very durable, but we suggest protecting your new purchase with a pool pad from Rhino Pad.

Rhino Pad is made from a special cloth fiber that is soft and durable. Defend your liner against cuts and punctures from rocks, roots, grass, glass and other harmful debris found on the ground. It will provide a flat base that gives an extra layer of armor for your swimming pool floor bottom prior to liner installation.

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.

The installation was easy. Two people completed the entire process from disassembly to installation in one day. The only dissatisfaction was that the new one was not as thick as the old one.

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.

The liner we ordered for 48 inch size pool did not fit. Supposedly it was supposed to be 52 to 54 inches, we couldn’t get it over three sides of our pool to overlap. So now I’m stuck with a non-fitting liner that was opened.
