I have two little girls, 3 & 5, who love the pool we have. It's a ring pool that we've not filled full so that it comes just to the shoulders of the 3 year old. I'm looking at getting a used metal sided pool at the end of this season and setting it up next year. I've done some research and know I'll have to get a new liner. This would be a DIY project and I have access to dirt moving equipment. What I'm wondering is there some way I could build up a shallow section in the pool? We're looking at about 24' round and will have to level some more yard for the larger pool. I was thinking of making a shallow section about 4' wide from one side of the pool. I'm concerned about the fill up against the sidewall on the inside, could it be countered with fill on the outside. Or does it need to be? Has anyone done this? Any suggestions would be helpful, including don't do it, but please explain why. If it's feasible what's the best way to transition to the deeper water? The difference in depth would be 12 - 16". I was thinking a slope of about 30 deg. I've got several if's and or's in mind for the whole thing, but I'll wait for some responses first.
