Well, it is true that there are few independent bathrooms in universities in the north.

Go to the big bathhouse

Some bathhouses have partitions, but most don't.

It's nothing if everyone takes a shower together. This is a natural habit. Shy or something, really not, they are all the same sex. What's to be ashamed of?

Of course, there are solutions,

You can go to the outdoor bathhouse outside the school to wash.

There are usually single rooms.

Or a double room!

At the same time, the weather conditions in the north can't be the same as in the south, washing every day!

Especially in winter ~
