Heated Shop Bathroom Vapor Barrier

I have a heated bathroom in my shop, 1 wall is an exterior wall, 2x6, insulated with a vapor barrier, the other 3 walls,2x4, and ceiling, 2x8, are interior walls, (shop side). The shop will be heated 45-55 degrees in the winter. My concern is moisture when taking a shower, I do have a very good cfm ceiling fan that is hooked to a timmer switch. Should I have a vapor barrier on these walls and the ceiling or is it OK with out, as long as the fan is run until all moisture is removed.

Thanks, Tim

A 45 degree inner wall can handle only up to 47% humidity coming from a 68 degree room.
