If I had a checkbook that big and was building a 60' pool I would go with Lucas Lagoons, they're down around Venice Florida, but they go all over the USA. They have the TV show Insane Pools Off the Deep End on HGTV. I think his basic pools are about $250K and up to a $million.
Lucas Lagoons Insane Pools: Off The Deep End
Back to the real world, this is a 16' x 32' pool 4' to 8' deep I had built in Pensacola a few years ago. It was just a little small for my taste. I sold that home and had a 18' x 36' the next home, I found that was a perfect size. I did add underwater lights, a diving board and more decking which this pool didn't have.
In Pensacola they do not use birdcages, they're not popular there, a fence around your yard is all the law requires. Here in TV you have birdcages because fences are not allowed and the law requires it. There was white coping around the edge because this was a vinyl pool, very popular in the panhandle of Florida. There is a plastic liner with foam padding underneath along the sides behind the liner. Makes it softer on the knees and feet. Vinyl pools are so much cheaper I don't know why in Central Florida they don't offer them, they probably can make more profit off concrete pools.
