Seller Verified Purchase

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

Seller Verified Purchase

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! 🫣
