In a typical busy restroom, women could wait as much as 34 times longer than men. That's mostly because women take longer — they menstruate, they have more clothes to remove, and they're more likely to have children or the elderly with them. But it's also because men's and women's bathrooms are often equal in size, which means men have more toilets. For equal wait times, experts say there should be at least three women's toilets for every one men's toilet.
