Millstone Pool

Located on Level 1 of the Athletic Complex, Millstone Pool features eight lanes with a moveable bulkhead that extends from 25 yards to 25 meters. The pool also contains a diving well with 1-meter and 3-meter springboards.

Millstone Pool is the home of the WashU varsity swimming and diving team as well as several WashU sport clubs, such as the men’s and women’s water polo clubs, the swimming club and the triathlon club.

The pool has hours set aside daily for open recreational swimming in the 25-yard lap lanes as well as in the diving well.

  • Log rolling is now available on Wednesdays from 5pm-7pm through April 27. Beginners are welcome. No experience or registrations necessary. Our friendly and trained instructors will teach anyone how to log roll like a Lumber Jack/Jill.
  •  Private Adult Swim Lessons are available for purchase to all members of the Sumers Recreation Center (currently paused due to shortage of instructors)
