Which type of residence has individual washroom? Or none of them

Les Prince has it. "Single with washroom".

McKay has individual washrooms shared by few "double rooms" but like once you are using it that is it, you lock the door and its ALL urs.

Bates and Keyes could also be considered "individual washrooms". You should check the housing website, it has all of this information on it, and you can make sure it matches your definition of "individual washroom", since that means different things to different people.

McKay has public washrooms, but they're single in the sense that it's single person use. There's a shower/tub, toilet, and sink. And you lock the door behind you.

Bates and Keyes aslo have single washrooms in the sense that they are only shared with the people in the suite/apartment.

Les Prince has doubles with washrooms and singles with washrooms. So you'd only share you washroom with your roommate or you got your own if your in a single.

A couple residences have a few single washrooms similar to McKay spread out throughout their building (e.g.Whidden), but for the most part every other residence has communal washrooms.

In addition to what Mohammad said, Hedden (best rez ever by the way ) also has a similar style as McKay.
