Good information everyone. Thanks again!
Make sure you talk about this part with a qualified (and insured!!) pool designer. Pool designs have been standardized in order to limit PB's liability with regard to diving boards. If you do a 20x40 pool with a 10 foot deep end, you will have a relatively small shallow end due to the slope required out of the deep end. The "slope" out of the deep end can be neither too steep nor too shallow (the idea is to allow a diver to deflect off of the sloped bottom in such a way that there is less likelihood of permanent injuries). Plus, in vinyl, the part below the steel walls, which are only 4', have to slope in from the sides in order to maintain the integrity of the structure. I'm not 100% sure, but I will bet that to get a "safe" 10' deep end, you will need to have a 22' x 42' pool or larger. Gunite would allow you to go straight down on the sides, so you could probably do something like a 20x42.
We have a 20x40 vinyl with an 8 1/2' deep end and diving board. I can easily touch the slope on a dive, but the kids have to try pretty hard. We always remind everyone to do SHALLOW dives and encourage jumping more than diving.
Good information everyone. Thanks again!
