What should replace the term "unisex washrooms"?

When we hear “we now have unisex wahsroom/s” what do we think it means? Let’s say it’s an institution of education or whatever else that serves tons of people. If we are picturing the wrong thing, i.e everyone regadless of gender, goes into the same big room with different stalls and urinals, which rightfully the vast majority says no way to, then what should the term be instead of “unisex washrooms”?
