In a Viennese sauna, confusion arose when a person with male genitalia entered the women’s area, but it was later discovered that the individual was a trans woman who had shown her ID at the entrance, which listed her gender as female. The city’s pool authority, MA 44, stresses that the gender listed on one’s ID is decisive for entry into facilities that differentiate between genders, such as toilets, changing rooms and saunas. The current rules for trans individuals require either „male“ or „female“ to be listed on their ID, and they are expected to use gender-specific facilities accordingly.
