Good/Bad Bathrooms?

I'm relatively new to the school and have heard the secrets of the good and bad bathrooms around campus. Anyone out there that can give me some heads up where the good ones are?

While I think this is a good topic, it's actually flawed in a way.

See the thing is, good washrooms tend to be the ones that few people know about. If we were to all discuss the good washrooms, it would result in more people using said washroom, and potentially result in said washroom being overrun and turned into a bad washroom.

....to help you out though.... Basement Buhler (or whatever that Biology labs building is called)

The washrooms in Engineering are great, however, there seems to be men's washrooms located in all of the convenient areas (outside the library, etc). It would be nice to have easier access to female washrooms.

Basically a quick rule of thumb: good washrooms are generally the ones that few people think to go to. The upper floors in almost every building are good as are the basement washrooms. Any floor that people don't access except for a lab or class will usually have a good washroom.
