Pool designer Lucas Congdon and his crew travel to Tampa, Florida, to build the most epic, adrenaline-filled backyard pool to date! He's creating two pools in one backyard with a nearly nine-foot high spa, two in-pool pergolas, his first-ever fire feature inside a grotto and a treehouse with a theme-park-sized slide. The project comes with a few challenges, however, when the clients request a last-minute addition and the sheer size of the pool becomes problematic.
