What are the conventions for refering to male VS female トイレ?


I just came across a sentence that used `男子トイレ` and `女子トイレ` and it got me
wondering. What is the difference (if there is one) between the `男子トイレ` and
the `男性トイレ`, and of course between the `女子トイレ` and the `女性トイレ`.

In English I would say the "men's room" and "boys' room" are, for the most
part, interchangeable, but I wouldn't use "men's" to refer to a bathroom in a
primary school, or use "boys'" in a formal setting.

If I had to guess I would say that this is the case in Japanese as well, or if
not it was simply a change in the degree of formality.




For a bathroom in a school, college or university, I think we use 男子/女子トイレ. I
don't think we normally say 男性/女性トイレ to refer to a school bathroom. I think
both 男子/女子トイレ and 男性/女性トイレ are used for a bathroom in other places like a
train station, company, department store etc...
