How much does a average built in pool cost?

That last answer was not very helpful. Installing an aboveground pool can cost $1,500-$5,000; for in-ground $7,000-$16,000 for a vinyl-lined model, $15,000-$25,000 for a fiberglass shell and $17,000-$45,000 for concrete or gunite. However, custom designs can run prices much higher. source: costhelper.com
