Where only one shower is provided, this needs to cater for users of both genders.
For a changing facility to count as an additional amenity, it must be capable of being used independently of any showers, otherwise it could not be considered as two facilities.
A shower which is a mixed gender facility must be capable of being used privately. As such, it requires adequate private changing space associated with it.
