A Texas man has built four enormous pools in his backyard. He wanted to create a pool experience that was 'second-to-none' , so he shelled out about $2.2 million to build his own personal water park. The backyard pool paradise includes a hot tub, a kiddie pool, a Lazy River and a Negative Edge pool. The lazy river pool includes a swim-up bar and a waterfall, and the hot tub can hold up to 30 people at a time. Even the kiddie pool has a huge water slide that’s 60 feet off the ground. The pool’s upkeep costs about $5,500 a month, without staff and bartenders, and the electricity costs another $3,500.
