Tony and Paul help a couple build their dream pool to go along with their newly built outdoor entertaining space. The guys embrace the challenge of designing around a giant concrete slab by creating a feature-packed pool that fits perfectly with the extensive new space. The finished product -- complete with grotto, slide, waterfall, barstools, spa, outdoor living room and cabana -- is sure to impress family and friends but the only way to be certain is to throw a party to test it all out!
