I'm 5'6" and the SO is 6'2". I'd like a deep end deep enough that we can tread water when we want to, and also allow some jumping in (no diving of course). I like the sport pool design since it also maximizes space for pool games which will be nice given the limited space we have to work with. I've been considering something like 4' to 6' to 4.5', which would be about a 1 foot change over 8 feet or so. The builder recommended shallower but said he'd do whatever I wanted.
Is there an industry standard or best practices when it comes to floor slopage?
