BARGOO I say do as you please. There is nothing rude about a normal shower noise.
That is something I deal with when working out of town, living in hotels and apartments....
noise late at night...after 8:00....
People taking showers and flushing toilets, air conditioners running, cars alarms going off, people hollering up and down the halls...
it sucks but that's life.
To her 5am is early to people like us it isn't.
Soap on!
