Generally, universities and schools will have public toilets, which are usually washed by everyone, but you can choose to go to the bathhouse outside to wash. But bathhouses are also divided into public rooms and single rooms. Usually, schools are cheaper, so everyone usually washes better at school. School dormitories will be equipped with toilets, but some people who want their own dormitories will decide whether to install water heaters (at their own expense).

In high school, many schools didn't have bathhouses, let alone wash them together.
