I am considering an in-ground pool 12x24. I've read about sports pools and how they have a shallow-slightlydeeper-shallow depth layout. So it could go from 3.5ft-5ft-4ft depths. Does anyone have experience with designing or using sports pools that are 24 ft long? It's not very long so is it practical to have 3 different depths? Has anyone seen a 24ft long sports pool that's 4ft-5ft-4ft? Is it better to just go 4ft to 5ft? Or is it better to make it all one depth (4.5ft)?
