And the school area is very small, but our school is exquisite, and each dormitory has its own bathroom. If there is no separate bathroom, it may be very troublesome, so I personally think it is very convenient to have a separate bathroom. Because everyone may have their own privacy, you can protect your privacy when you want to go to the toilet or do other things, which is cleaner.
Moreover, it is more convenient. If it is really a public toilet, it may take a long way to go to the toilet every night, or it may waste time and make everyone have a bad rest. Therefore, there is an independent bathroom, and everyone can go to the bathroom if they want, which also provides convenience for everyone. I went to some university dormitories, and I saw that there were also some dormitories without public toilets.
These schools are generally not very good schools, so their dormitories are rough, and then there is no separate bathroom. Therefore, university dormitories do not necessarily have separate bathrooms.
