Try Intexcorp.com for a replacement without all the other stuff you already have. I was just there and found a new liner for my 15 x 48 metal frame Intex pool ($167.00 compared to $349.00 for the whole kit) as I didn't need all the other acessories either. This liner I am trying to find reviews on says with laminated bottom which I am hoping means it has an added layer of protection on the bottom as my other one was very thin plastic. I got frustrated last year with no one wanting to help take it down and actually thru it in the trash! I think I need to work on my temper a bit! lol

I did see a 15 x 36 replacement on the easy set but don't know what size you actually need. Good luck.
