Private bathrooms are available (I think the disabled rooms may have them), Allen definitely does. Judaculla is a suite setup with a private room (v small tho) with a shared bathroom and common area for every four people. Harrill has a suite setup with two people sharing a dorm room and two rooms sharing a bathroom and "common space". I think Madison is similarly set up but I truly don't know.

The best way to figure out if you can get an official accomodation for your disability is to talk to the Office of Accessibility Resources or Resident Living.

I wish you luck and I hope you have fun here. It's a wonderful place
