This thread is awesome...i am getting ready to try this. I have a 16"x48" Intex ultra frame. I found a brand new 15x52 beaded replacement liner and am getting ready to give it a try. Anyone have an opinion on whether the 15" will fit inside the 16' frame. All my friends say it will stretch with the water weight. I think it will too.....Ill keep the forum inforumed
