The lap pool: Lap pools are built so that people can swim laps for health and fitness. They tend to be long and narrow, usually over fifty feet long.
The diving pool: These pools are built deep; diving pools are usually 3 to 6 m deep with a diving board or a platform, or a jump tower. The Olympic diving tower has platforms at 1 m, 3 m, 5 m and 10 m height.
