I am searching for a liner replacement for my above ground Coleman pool which uses the tube poles. The issue is the size. I currently have a 21' by 52". I built a deck around the existing pool and with the excellent care have had it for 7 years. It now has 3 leaks so time to replace. In all my searching I find all overlap liners in the 21" My deck cannot be adjusted to accommodate any other size. I also have tried to find a contact for Coleman pools. If I find the right 21' pool I might consider just replacing the whole thing rather than just a liner. Suggestions?
