Thank you all so much for the info! I'm going to read all the threads carefully but let me ask you this, and I know I'll have tons more questions, but we want a deeper dive pool than standard of 8 ft. I really wanted 10 ft depth but a local pool builder told me this past week that they don't recommend a depth of 10 ft because of the slope of the hopper. Now, my thought was that when you have a deeper depth, that meant you would have a longer slope so it would cut more into the amount of shallow area that you had but I didn't think that deeper meant that you had a steeper (and at and least from my understanding of what he said) a more dangerous slope. My main concern for the depth was that I'm not sure 8 feet is really deep enough for a diving pool (I know that's the standard but I'm paranoid) so I wanted it to be more around the depths that you'd find at a commercial pool but I know those are typically gunite and are constructed differently on the deep end. So what is the real answer about the slope? Go with a standard 8 feet depth and not worry about it? My husband loves to dive and he's 6 ft tall so the depth at 8 ft really concerns me. I've also got a whole lot of plumbing questions but I'll save that for another day, ha!
