Susan:  Why is the bathroom so important in Potterverse?
Many big things have happened in the bathroom...
-A Troll attacked Hermione in PS/SS

Me:  Hermione went to the bathroom so she could cry, and Harry and 
Ron locked the troll in there, since they didn't know she was in 
there. The troll probably smelled Hermione or something and that is 
why it went to that specific toilet.

Susan:  -Moaning Myrtle haunt a toliet in CoS onward

Me:  That toilet is where she died, so presumably it's her favorite 
spot. Besides, she does go to Nick's party, and in GoF she goes to 
the Prefects bathroom

Susan:  -The Polyjuice Potion was brewed and kept hidden there in CoS

Me:  Well, assuming that Moaning Myrtle spends most of her time there 
and she also floods the place, it wouldn't be too pleasant to go 
there, so it's a convenient place to hide a zonking big cauldron with 
Polyjuice Potion in it, since no one (except for the trio and Myrtle) 
go there.

Susan:  -The entrance to the Chamber of Secrets was in a bathroom

Me:  The bathroom would prove to be a most convenient place to create 
an entrance to a place that is miles below the ground, under the 
school, because of the pipes and everything. Would be much less 
conspicuous if the entrance to the Chamber of Secrets were hidden 
behind a painting.

Susan:  -Harry figures out the second task in the prefect's bathroom 
in GoF

Me:  That is because Cedric has given him the password to get in 
there, so that he could figure it out in private, on his own.
Besides, the egg had to be plunged into the water to solve the 
riddle, which made it a convenient place to be in.

Kateydidnt:  Trevor the toad was found lurking behind a toilet...
actually i don't think it really has any big significance, but it 
would certainly be interesting if that turned out to be the case

Me:  I think it makes up for the almost complete lack of references 
to bathrooms and toilets in Star Trek :-D Besides, we spend a large 
portion of our lives in the bathroom, it's only natural that a story 
about people will incorporate that particular room in one way or 
another.

Happy Hannuka, Christmas, Thanks Giving, (any other holidays that I 
don't know about) :)
