  • MEASURE TWICE, BUY ONCE – Whether installing for the first time, or replacing an existing liner, the Waterfall 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 Waterfall pattern brings nature to your pool with the top border of white water cascading over the edge of a rocky cataract. 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 Waterfall liner.
  • HIGH QUALITY MATERIAL - Swim care-free 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.

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.

I ordered this in the winter so we’d have it ready to install as soon as it warmed up. That was a big mistake. We were initially able to get the liner attached to the pool walls but with minimal overlap, but when we started adding water we found a 1” tear in the bottom. After repairing the tear, we went back to adding water and it did not stretch enough and will not stay attached to the pool walls. You can tell it is the wrong size because the pattern on the liner, which should change near the waterline, changes less than halfway up the wall. Swimline claims a 25 year warranty but no one answers the phones or calls you back so we’re just out $250. If you are going to buy this, make sure you install it before the Amazon return period ends.

So far it’s done great. Bought this back in the summer and it was super annoying to get installed. Once we did its held up great. We’ve got about 8 inches of snow right now and the poool is frozen. It’s held up well so far!

So far so good. Got a bad liner after a wrong size liner from online pool company who wanted all but $10 of full price for warranty replacement after 60days. It had a seam leak on delivery that we did not know until the bottom was mushy and ended up being a $700 replacement cost. This one is fine. I love the pattern. NEED TO KNOW THE 25 OR 30 YR WARRANTY WITH ANY OF THESE IS A LIE. After either 60 or 90 days, you will just need to buy a whole new liner so becareful where you buy from. Can't speak to durability its only been less than 2 months.

Color and pattern are great. Seems to be holding up well. Delivery was fast and fairly easy to set up in the pool.

This liner came in fast!! We bought a 18 by 48 ft Intex pool about 5 years ago. The liner on this pool is the actual pool- wall and liner in one. So I bought this liner after months of debate. It works. I installed it and used some green house clips to secure it to the top bars of the Pool which also worked perfectly and the liner is in and it is AWESOME!!! We had to cut our own holes in the liner for the pump fittings.This liner did tear easily, lucky for us I noticed it right away. The clips are what tore it not us handling just the liner by our self. I do recommend this liner, it looks great and it works perfectly to fit our needs. Thank You Swimline!

Nice and strong, very pretty, fairly forgiving as to stretch and positioning. We did our liner replacement ourselves and although it was a lot of work, the end result was great. Also, for what it's worth, our pool is unheated (sunlight only) and our old liner was the default solid turquoise, much lighter in shade than this liner. Since installing the cracked glass liner, we've noticed a significant increase in pool temperature (5-10 degrees F warmer)--I'm assuming the darker color is absorbing more heat.Recommend having at least 2 people to install this. Also, we put down a Gorilla pad prior to installing this liner-- wanted that extra protection for the pretty new pool bottom!!
