Hey everyone, I live in a dorm with a strange bathroom/shower setup. The first floor is shared by both guys and girls, and we have three rooms with combined shower/toilet facilities. So, if three people are showering, you're out of luck if you need to use the toilet. The second floor has the guys' showers and both male and female toilets. The third floor has girls' showers and both male and female toilets. The fourth floor seems to have it all - both male and female showers and toilets.

Recently, these bathrooms have been overcrowded, and I've noticed students from other floors coming down to use the first floor's bathroom. It's honestly really inconvenient to go all the way to the second floor when it's not necessary. They could use the third or fourth floors, but they still choose to come to the first floor. I've politely asked them not to use our bathroom, especially since we don’t have separate showers and toilets, which makes things more difficult.

But, after explaining how inconvenient it is for everyone - including them - they were pretty rude and insisted that the bathrooms are 'public property' and they can use them wherever they want. I get that, but I ended up arguing for about an hour to try to get my point across.

I'm just frustrated and wondering if there's any ethical (or even a little sneaky) way I could prove my point without escalating things further. Any advice?
