The Government has announced that all new public buildings must have separate male and female toilets.
The Department for Levelling Up, Housing and Communities said that unisex toilets should only be provided if there is space and should not come at the expense of female toilets.
It said this approach would ensure women, who may need to use facilities more often for example because of pregnancy and sanitary needs, have appropriate facilities.
Minister for equalities Kemi Badenoch said: 'It is vital that women feel safe and comfortable when using public facilities, and that their needs are respected.
'These changes will ensure that separate toilets for men and women are preserved at the same time as providing universal toilets for those that want them. This is a common sense approach.'
The Government will launch a consultation in the autumn to consider the design of unisex self-contained cubicles and whether improvements to disabled persons toilets should be made.
