I'm going to be honest; this picture doesn't even represent the least passing trans women. I know there is a whole thing about what is/isn't a woman but ignoring that - this isn't how toilet rooms work. I also think (as does everyone I've ever talked to that urinals shouldn't be put in women's toilets because even if you accept that (whichever group) of people are women, they are such a marginal amount of women that it'd just be... pointless.
So ignoring urinals (which aren't and should never be in women's toilets) there are always stalls in toilet rooms.
Sorry for the rant but thank you for reading.
