The average above ground pool will last 7-15 years before the structure gives out, although their liners will last 5-9 years before they have to be replaced. For an in ground structure, the longevity really is contingent on the type of pool. For example, fiberglass should last well over 20 years.

The installation costs of above ground pools usually run $1,000$3,000, depending on the size and type of pool. Keep in mind that oval pools normally cost more to install than round pools, and the kits are also more expensive

At this point it's worth mentioning that all round shaped above ground pools are capable of having a deep end/center. Most ovals, though, are not capable of having a deep end/center. Most oval pool designs have metal straps that run under the pool's bottom and therefore it will not allow you to dig your pool deeper
