So I was wondering, how would the bathrooms work at Hogwarts? Are they communal? Suite style? How many do you think there are in the common rooms? One for girls and one for boys? One for each dormitory? Where do you think they would be located?

Also, are the students required to bring their own supplies - shampoos, soaps, etc? Or does Hogwarts provide them? And would they be shared?

Basically any info on the bathroom status at Hogwarts would be much appreciated.
