I'm writing a fictional story based on the Titanic, and I have a few questions about the swimming bath/swimming pool (which I'm going to incorporate into my story). The concept of the bath/pool is slightly confusing to me, partly because I've heard the term being used interchangeably. Does this mean that the swimming bath and the swimming pool are the same thing? Or are they different things? And if they were the same, would you normally be allowed to swim and bathe (take a bath) in the same area? (A somewhat disconcerting thought, but you never know).
Thank you for your help in advance.
