The shallow end of your pictured pool looks to be level, or perhaps it's slanted down as you progress toward the deep end. But I'm considering on buying a house (owner is deceased) where the shallow lounge area is highest at one (the right) corner of the pool, and it gets slightly deeper/is slanted as you move left and towards the deep end. I hope my description makes sense. Assuming it does, do you happen to know why the shallow end would be designed this way?
