Digging Out Center of Pool
I've purchased a 24' round pool and I'm considering digging out a concave circular area about 18' round in the center.
The pool wall is 52" tall and I'd like an 80" depth at center. I'll keep a level shelf along the outer wall of the pool. Do you think this will stretch the liner too much? I've done this with a smaller 15' pool with great success.
There is nothing wrong with doing this as long as you have an expandable liner. Expandable liners will allow you to dig an extra 2 1/2 to 3 feet deeper in the center. Never try it with a UD, uniform depth, liner. They are made for flat bottom pools only.
Be sure to follow the instructions on the expandable liner page, this will, in most cases, assure a wrinkle free installation.
