Unisex public toilets can be used by people of any sex or gender identity. Such toilet facilities can benefit transgender populations and people outside of the gender binary. Sex-separation in public toilets (also called sex segregation), as opposed to unisex toilets, is the separation of public toilets into male and female. This separation is sometimes enforced by local laws and building codes. Key differences between male and female public toilets in most western countries include the presence of urinals for men and boys, and sanitary bins for the disposal of menstrual hygiene products for women and girls. Sanitary bins may easily be included in the setup of unisex public toilets.
