Well, it is of great interest to me. I've been rough sketching a bunch of shapes and layouts in the area we want and I think we have decided on orientation now. We want a dive pool, 18X36 free form, 3'6"-9' deep. Deciding on a shape is really tough and I have sensory overload looking at pool pics for the moment. I just don't want anything square or plain kidney shaped...you know, something a little different. I don't have a sketch worthy to post, but I may do this too. I like yours and think its a great shape. Your lights are in a good spot, and I love the waterfall, bench, and rocks. If I may suggest, you might like the look of the rocks below the waterline. This is a feature that I am really starting to desire badly. I just don't know if our budget will allow a water feature, but if we get one, I want some rock below waterline. If not, I still may try to aquire this feature in some way.
I haven't drawn out any plumbing yet, but that's interesting too. Are you going to build this pool yourself? I have thought about being my own GC, but it's a scary thought. If this wasn't my first pool, I might try to pull that off. My mind is buzzing with everything about the pool right now and it is all consuming. Look forward to hearing more from you, and maybe this will inspire me to lay something out here to share as well. I need to get some current photos of my yard where we want it, and spiff up a sketch or two. Speaking of which, I need to get off my rear and go mow it. :lol:
