You have to control all the moister you can, squeegee the walls of the shower when finished
put damp clothes outside warm living qtrs? buy a small dehumidifier, heat with electricity rather than propane, vent the unit with fresh dry air... what is happening is the warm moist air is raising to the ceiling and condensating where the insulation is the thinnest.
The more you control moister to condensate, the easier it is to control moister build up at the ceiling and windows.
