The university and SU have policies defending the right of all students to use the gendered facilities that they feel most comfortable in. However, not everyone is comfortable using gendered facilities. If this is the case, you are fully entitled to use the gender neutral facilities on campus. This covers both toilets and changing rooms. You shouldn’t have any difficulty accessing these facilities, but if you do please email email@example.com.
To use the gender neutral private cubicle changing facilities at the Sports Centre, just ask at the desk. You don’t need to give a reason as to why you wish to use the facilities. After you’ve initially been shown where the facilities are, you do not need to ask at the desk on future occasions.
