Just joined the forum for some much needed help with our liner. We have a what we thought was a 30ft round 52” Ht. above ground that needs a liner to be replaced. We measured from post to post and we come up with 29ft 5” we then did a cross hair and got the same measurement.We purchased the pool here in the states 12 years ago and was told it was a Canadian built pool. It has 21 posts and everything besides the walls are made of resin. I believe it’s a beaded liner. With all that said will a 30ft round liner replacement fit our pool. We were told by the pool store that they would have to have a liner cut special and would cost over $1200. Was wondering if anyone has ever heard of this situation before?
