I don’t know how this’ll go down but I think all facilities should be gender neutral. I don’t see the point of segregating it. What’s in someone’s pants is their business and possibly their GPs too. If all facilities weren’t communal, people could still have their private spaces. My favourite bar has gender neutral toilets and they’re great (also means less queueing for women which I would greatly appreciate). I detest communal spaces anyway and feel them a great invasion of privacy. If there are ample options for example bigger toilets/changing rooms for parents and young children and disabled people it would work well. Also, if there was only one set of toilets, they would be easier to monitor and if that’s done well there’s no danger. Just my opinion though!
