Shanghai's first unisex public restroom, designed to help reduce waiting times for women, is failing to woo users, especially females.

The restroom's automatic tally device showed that only about 100 people a day have used it since it opened in November, a rate far lower than other public restrooms in the city.

That could partly be a result of its secluded location - a green space in the city's Pudong New Area that is far from bustling streets or residential areas. Most users are migrant laborers working nearby, with only about 10 percent of its users female.
