Im getting started designing my pool and its time to decide what depth we want. Our yard is only big enough for a 20ft long by 12ft wide pool so we were thinking it might be fun to do a sport pool with a deep end in the middle, shallow on the ends. I was thinking 3.5ft to 5.5ft to 4ft deep. I was wondering though if 20ft is enough length to have the transitions needed and still have a decent sized shallow ends. This is for a inground gunite/shotcrete pool.
