An interim update from the EHRC, published in May, said that “trans women (biological men) should not be permitted to use the women’s facilities and trans men (biological women) should not be permitted to use the men’s facilities, as this will mean that they are no longer single-sex facilities”.
However, a response from Museums Galleries Scotland (MGS), which supports around 455 non-national museums and is funded by the Scottish Government, said EHRC’s proposals may “force some museums to close”, or “risk leaving trans people with no facilities at all” if changes could not be made.
Adding these is usually the way to solve it. There wouldn’t be enough room to completely convert existing without losing a lot of capacity.
