Mario Lopez wants to give a family of six a supersized happy ending; their contractor disappeared halfway through renovating their dated -- but functional -- pool, leaving behind a demolished danger zone of a backyard.

Mario builds a kid-friendly backyard fun zone for a pair of Air Force veterans and their family in Las Vegas.

A family of six finds the ideal house and yard, but a stained deck, chipped pool and ugly hill mar the experience. Mario Lopez brings in his team to create a backyard water park featuring a waterslide, grotto and a VIP cabana.

A Las Vegas family has watched their pool area deteriorate in the desert heat, making their backyard nearly useless; Mario Lopez comes to the rescue with plenty of shade, a T-shaped pool, huge spa, water features and plenty more.
