The Swimming Pool Floor

As dictated by u/ReactsWithWords, this floor is the swimming pool floor. There are a number of different pools on this floor:
A shallow Olympic-size pool with lane barriers. This is strictly for swimming laps and competitions.
A standard Olympic-size pool. It starts out shallow (3 feet, approx. 1 meter) at one end and gets pretty deep (10 feet, approx. 3 meters) at the other, with the depths clearly marked. At the deep end is a regular diving board and a high-diving board.
A very shallow kiddie pool.
A half-sized low-chlorine pool (uses salt and ultraviolet light). There’s still chlorine in it, but not much more than in your average tap water.
Lifeguards are on duty for the latter three pools. The first pool is monitored by AI drones that save anyone in trouble, due to the large amount of traffic making it more difficult for humans to see when someone is in danger
