AITA for moving my roommates stuff?

My (18F) roommate (19-20F) has been very disrespectful of our shared space from the start. We are in a college dorm that has two rooms and a common kitchen and bathroom space. She has always treated the common areas like they are her own personal home.

I won’t even get into all of the inconsiderate disrespectful things she has done/still does, but our main issue is the bathroom. I keep all of my belongings in my room including my toiletries (I’ve even gotten a personal fridge and microwave for my room because she is so dirty). She stores a lot of her belongings out in the common area. She also has an over the door organizer on the bathroom door. The shower is very tiny with two shallow shelves that fit a bottle each, two if you really balance them.

Here is where the problem is. Even though she has the over the door organizer that you can reach from inside the shower, she keeps like 13 bottles of shower products on the shower floor and one on each shelf. This is what makes me think of her as inconsiderate because I don’t know where she thinks I am supposed to put my things when I shower. Does she expect me to hold everything between my legs and strategically shower?

Well the first few times it happened I moved them when I showered and put them back and then texted her asking her to leave at least one shelf open after she showers so I can have space. She ignored my text, did it about one time, and started doing it again.

So I started moving them to the floor and not putting them back after. I was doing this for a while and she still didn’t get the hint that she shouldn’t leave her stuff there. So one night I got a text saying don’t touch my fucking shit again. So apparently one of the bottles I moved didn’t have the cap all the way on and when she got in the shower she kicked it over and like half of it spilled. I told her sorry but it’s not really my fault that she leaves all of her products in our shared shower.

My friend think I should have just knocked on her door every time I have to shower and tell her to move her stuff so that she gets conditioned to move her stuff. But I don’t think I should have to wait on someone to do something just so I can get clean in the dorm I’m paying thousands for. So AITA?
