  • MEASURE TWICE, BUY ONCE – Whether installing for the first time, or replacing an existing liner, the Caribbean 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 - The Caribbean pattern gives a delightful depiction of exotic fish swimming around your pool. 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 Caribbean 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.

This is the third replacement for my above ground pool. I really think that this is the last one. It was way easier to put in than the last one. It's very thick and durable. All my friends love the fish swimming around..... looks great!

It is a very nice liner with vivid colors. The universal gasket was not included but I reached out to customer service and the sent it out immediately! It was an extremely tight fit and needed to be perfectly lined up, but it was worth the work to see the kids faces when they were able to swim!

Who needs a plain liner? This liner is colorful, beautiful and sturdy. We just installed it and will be able to tell how well it hold up over the course of the next few months. Other then that it is really a nice liner. 10/10 recommend.

Pool didn't come with any seals or gaskets!!!! Saw that in a previous review but we thought it was corrected by the sellers. Nope

The liner is beautiful and I can not wait to swim with the fishes. The installation sent smoothly. The only issue I had was the gaskets were not in the pack. So we had to go out to the local pool supply store and purchase gaskets.
