We are still designing our inground pool. The builder has sketched a diagram in which shallow is 48 inches. The deep is 5ft 10inches. I want the slope to be very steep so that the transition is narrow and we can enjoy more deep end. I have read about the 1 to 3 ratio. I have read that doesnt have to be adhered to in residential builds. Our builder sketched that the depth transition would occur over a 3 ft spread (or tread if that is the right term). What do you think if we have a steeper slope and only waste 2 ft in the slope to get down to the 5ft 10 depth? That would be 2 ft going forward while transitioning from 4ft to 5t 10.
