Yep. I have a chamber chair. I empty it about once a week.
I have one that you enter from the master bedroom.
if you count my waterbottle. Sure :D
I have one connected to my bedroom.
Not quite, but I share a bathroom with the bedroom next to mine; the bathroom itself is only accessible from either bedroom, so it's only used by me and my roommate.
Yes. It is not a fancy one but it serves it's purpose.
Very very close to bedroom
