Review on Upgrade Your Above-Ground Pool With Smartline Swirl Bottom Liner - 18Ft Round Overlap Style, 20 Gauge Virgin Vinyl, Designed For Steel Walls, 48-52 Inch Height by William Lin

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!
