POOL will be 18x 36 feet rectangle with an 8foot wide step centered on the south 18foot end of pool.

We want to make the south side the shallow end with the steps. But we are wondering what makes a good depth for the rest of the pool.

We have smallgrandkids, so we do want to have that shallow end.

We want to be able to play basketball and volleyball in the pool.

I have seen drawings that show shallow end at 40inches and deeper in center then return to 40 inches on the opposite end.

We expect the pool to be used socially a well,maybe hanging out in and out of water with adults possibly having a few drinks.

One thought was to start at 36-42 inches on shallow south end, then slope to a depth of 52-56" on the north end. This way there wouldn't be two slopes(only one) and the volleyball game might be more fun and fair if no one is needing to tread water or struggle to play.

Then how much of each depth is reasonable to make sure the pool is best usable for both small kids and adults?
