Not only does it look great but the quality is wonderful and the service was above and beyond. I initially bought the wrong size and they gladly exchanged for the right size. The shipping was super fast and my account got credited the day the wrong liner got back to them. Im very impressed by everything!

I bought the liner with cove moulding and a rhino pad. The 25 mil liner seems plenty thick but still will stretch where needed. I did it with no help one step at a time. Tamp the sand down when damp and add the pad.it came out pretty smooth, better than before.I think cove moulding is necessary

This was the wrong size for us but we got the 27 foot and the pool is filling as I type! Install went very smooth, of course it's our third or fourth time installing a liner. Thanks for great customer service! We were disappointed that we are stuck with the wrong side and can't return it! 🫣
