To answer Tammy's question directly, the Olympic had it too. It was actually referred to as a Swimming Bath in the First Class Accommodation Plan, and you needed to schedule time to use it, as also the electric baths on the other side of the watertight bulkhead aft. Ladies hours from 10 AM to 1 PM, Gentlemen hours from 2 PM to 6 PM. Tickets were $1 each. Gentlemen could have access to these baths free of charge from 6 AM to 9 AM.
