Potty parity

Male cubicles and facilities were typically greater in number until the late 1980s and early 2010s, depending on the country and building.

Multiple studies have found that waiting times for females can be reduced by the use of properly designed washrooms.

Since men's and boys' bathrooms include urinals, which take up less space than stalls, this still results in more facilities for males.

[1] The lack of diaper-changing stations for babies in men's restrooms has been listed as a potty parity issue by fathers.

[4] John F. Banzhaf III, a law professor at George Washington University, calls himself the "father of potty parity.

"[4] Banzhaf argues that to ignore potty parity; that is, to have merely equal facilities for males and females; constitutes a form of sex discrimination against women.

[3] Public toilets have historically been divided along the lines of sex, race, class, disability, and other distinctions.

Until the 1980s, building codes for stadiums in the United States stipulated more toilets for men, on the assumption that most sports fans were male.

[4] The Act was amended in 2000 to empower the state architect to authorize extra men's rooms at stadiums, horse shows and auto racing venues.

[12] Current laws in the United Kingdom require a 1:1 female–male ratio of restroom space in public buildings.

[18] In 2013, the state of California passed bill 1266 ("The School Success and Opportunity Act") requiring provision of facilities consistent with a pupil's gender identity.

"[20] Newfoundland and Labrador's Occupational Health and Safety Regulations, 2012 state that "where both males and females are employed, separate toilets shall be provided and suitably identified for workers of each sex".

The by-law stated that "There shall be provided for employees, toilets separate for each sex and at least one toilet room and one hand washing facility for customers of each sex of any restaurant designed to seat 25 or more customers..."[25] On 19 February 2012, some Chinese women in Guangzhou protested against the inequitable waiting times.

Since March 2011, Guangzhou's urban-management commission has ordered that new and newly renovated female public toilets must be 1.5 times the size of their male counterparts.

[32] Thus, activists have collected more than 50,000 signatures supporting their demands that the local government stop charging women to urinate, build more toilets, keep them clean, provide sanitary napkins and a trash can, and hire female attendants.
