It's a good question. With no diving board, there isn't much point to having a traditional deep end, but it is nice for the kids to jump in without hitting the bottom. I would imagine the contractor can make a semi-deep end...5 feet or so.

My pool is 3' to 9' deep because of the diving board, but when family is floating around (not the diving kids), they hang onto what we call Doodles - 4 foot long inflated tubes, and there doesn't seem to be any point to variable depth.
