Ladder for Sloped Pool Walls

[AirRev]

Hi. New to the forum. I moved into a home with an older amoeba shaped concrete in ground saltwater pool. I'm guessing 1950's or 60's. At the end of last season, my pool company told me I'd need a new ladder. They recommended and purchased a Saftron Elite 3-Step. When they came to install it, they realized that our pool walls are sloped/curved so that as they descend they curve toward the middle of the pool (kind of like a bowl). As a result, the ladder won't sit flush on the pool deck. Wondering if anyone has run into this and how they've solved for it. FYI, we would prefer a resin ladder so that we don't need to tear up the pool deck to bond the ladder. Thanks in advance!
