These pool designs are built for a day of fun in the sun with loved ones. A tropical Texas oasis incorporates a stained glass window inside a custom grotto, while a stone fire pit sits in an unlikely location. A French-inspired tower is built around a tornado slide, and a backyard pool comes with an outdoor movie theater. Then, a lakeside pool features its own private helipad, and a last name inspires a letter-shaped pool with a bridge-accessible island.
