I think what bothers me is that this has been driven by the transgender/non binary community. And what the Barbican has done is come up with a quick fix solution without considering others not in that category. If you were starting from scratch, as some concert venues have done, then you could have a corridor with cubicles off it, each one with its own washbasin , dryer and rubbish bin. The reality of the Barbican IMO is that most women will not go into the one with urinals ( and some men may feel uncomfortable if they do). At the Barbican apparently, men were going into the non urinals one however but not vice versa. I do think that women ( and men) who prefer separate facilities should be able to have them - perhaps there should be men, women and gender neutral. I fail to see why at a public venue, why there was not any consultation. I've used shared facilities in France but they were in smaller cafes and restaurants. In most hotels and more upmarket restaurants, the facilities were completely separate- but that's not really relevant, this isn't France.
