Features

  • MEASURE TWICE, BUY ONCE Whether installing for the first time, or replacing an existing liner, the Tidal Surge 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 21 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 Tidal Surge 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

  • 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

  • Smartline is a joke
Material Type: Crystal Tile Size: 30' Round
Do yourself a favor buy a liner from a better company than smartline pool anything. This company smartline is all about profit and does not stand behind there product and they want to screw the buyer over any chance they get. Do yourself a favor people buy a liner from a better company that actually stands behind there product and won't blame the buyer for the company's mess ups. 100 more on price and I got a liner that is guaranteed to be defect free and if an issue they cover shipping back and send a liner so u dont have to wait 8 weeks or longer to get another liner and have to pay to ship it, unlike smartline what a joke they are for real. ... show more
