We have an 18x48 Intex quick set pool (not sure if that is the name, the one with the inflatable ring) and I was thinking about when it fails, upgrading to a 22x52 Ultra frame but after reading some of the posts it sounds like it is just a lot of additional cost and a bunch of hastle just to get a slightly bigger pool that is only 4 inches deeper and the extra money would be better spent elsewhere. Thoughts?
