My partner & I visited the British Library today for the first time in ages & were both pretty pissed off (no pun intended) by the women's toilet provision.
The picture is of the toilet doors in the main area of the ground floor. That's bad enough, the reality inside is that the men's toilets were 'enormous' (partner's words) with both cubicles & urinals - enough for about 15 men. The other one was one toilet - clearly the accessible toilet now supposed to serve everyone else - oh and men too 
The women's toilets referenced in the sign had 7 cubicles (including one larger cubicle, although I am not sure it would have been big enough for wheelchair access). Next door was another men's toilet - 7 cubicles + similar number of urinals.
I cannot get over the disparity in provision and the the fact that those needing the accessible toilet have to share with absolutely fucking everybody.
My partner complained in person - the woman on the information desk positively encouraged him to fill out a form. I'll be emailing my complaint this evening.
