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.

stretch liner

I see your answer to only use expandable liner. What about these replacement liners that do not say "expandable liners" and do not say "uniform depth" but say they will stretch to fit slightly dished center? How slightly? Could you use one of these liners in 24 round 70'dished center above ground?


If you were buying a Doughboy expandable liner I would say yes, it would fit. With any other brand, labeled the way you say, I would check first. Any place you are thinking of ordering a liner from should have a phone number where you could call and ask for sure. I would do that before buying the liner. If there is no number, don't buy it.
