Women often are flushed with indignation about public bathrooms. There just aren’t enough places to answer nature’s call.

For years, men have enjoyed the in-and-out nature of their bathrooms and biology, but women, generally, need more time and space.

Building planners have seemed to neglect this ladies’ bathroom backup for too long.

But the same laws that require gender equity in college athletics may lead to a change.

A complaint filed with the U.S. Department of Education could halt a $38.6-million upgrade to the University of Michigan’s Hill Auditorium because of this “potty parity.”

Some say that because the auditorium has 60 percent more male restroom facilities than code requires, compared to only 1 percent more female restrooms, women face a greater burden in going to the bathroom in the building.

U-M officials should take care to rectify this situation.

It only stands to reason that women should have the same number of facilities to use as men, no matter the space it takes up. More than 10 urinals can fit into the same space as three stalls, which gives men a distinct advantage when it comes to making a pit stop.

Evidence of this bathroom inequality is all too common at sporting events, shopping centers, schools and other public places. The line for the women’s bathroom certainly doesn’t make a restroom break an inviting experience.

Of course, it’s a shame to have an issue like this complicated by a legal battle.

After so many years of working to overcome gender disparities, such a seemingly trivial issue should have been solved long ago. Instead, it’s interesting to note that the battle for gender equality has moved from breaking the glass ceiling in the workplace to a tussle over toilets.

Nature’s is a call that can’t be ignored - regardless of gender. We hope the matter in Ann Arbor is resolved soon, instead of being stalled in discussion.
