Other studies have shown that women take about one and a half to two times as long in the bathroom and a lot of this has to do with practical aspects such as more doors having to be open and closed (comparing to men using urinals), and more clothes having to be taken off and put back on.
The combination of these two factors leads to longer lines, especially at busy times (like at the end of a concert, when everybody heads home).
The solution? Unisex bathrooms (which have the added bonus of being transgender-friendly and, as such, shutting down a whole other social debate).
The researchers found that moving to unisex bathrooms would cut women's waiting times from over six minutes down to less than a minute and a half.
The unisex bathroom, that researchers described as "the holy grail" should have a ratio of two stalls to one urinal, allowing men to use urinals and both genders to use the bathroom stalls.
The experts concluded this new configuration would reduce overall wait times by more than half (about 63 per cent, in fact).
