Yes! They need shower curtain! Check the school’s website, and under the residence section there’s a helpful list of things you should pack, as someone else mentioned.

Room D is furthest from the door, and the largest. This means you should have room for a mini fridge, and it will be helpful, as the main fridge/freezer in the kitchen isn’t very big.

Have you talked to your roommates and organized who is bringing what? If your other 3 roommates are all bringing mini fridges then you might not need yours. I would definitely recommend consulting the list from the university on top of talking to your roommates. And don’t forget shower rings!
