Space as a gender adjacency and sexuality's spatial dimension are recent themes in architecture. The case of the bathroom as a gender-regulating device is a constantly discussed topic at the intersections of queer theory in architecture. The discussion is even broader within LGBTQIA+ guidelines.
The philosopher Paul Preciado, in 'Garbage and Gender', points to toilets and urinals as gender-demarking devices: the condition of sitting on the toilet or watching/being watched at the urinal, guarantees the perpetuation of the hermetic nature of male and female gender binarisms. Women urinate seated in private stalls, while men do so standing up in collective devices. Therefore, by this logic, men who use private stalls are "less manly". Another interesting example of thinking about genderifying spaces is the alcoves, traditional environments in colonial buildings in Brazil. These environments functioned as devices of segregation and surveillance for virgin daughters. These small, unventilated rooms were usually located in central areas - next to the hallway, kitchen or living room - to allow family control.
