Earlier quoted context omitted.
Just make them all unisex. What's wrong with unisex bathrooms, so long as they have partitions and not troughs or heads out in the open and have the urinals sectioned off at one end.
I answered this in my post... > I have no issue with gender neutral bathrooms, but from what I hear around the watercooler, women's bathrooms are a LOT nastier than men's (or at least that's how women tell it). Too many women trying to hover and getting it wrong.
And if hovering is an issue then clean nightly so people don't feel they need to hover and second educate. Talk about it... Lastly think about squat toilets. Easy maintenance.
