<p>Some of them are, but not all. Each hall votes at the beginning of the year to determine how they want their bathrooms to be gendered, based on what the residents are comfortable with. They could make the whole facility all-gender, or leave the sinks and toilets open to everyone but have separate showers. Or they could have divided men’s and women’s bathrooms - the drawback being that since most halls are co-ed and many only have one bathroom, half the residents would have to go for a hike in order to pee, and trans students would be out of luck.</p>
<p>The “E system” is getting more and more popular as a compromise. You put a cardboard E outside the bathroom, which folks can rotate to determine who’s allowed in at any given time: E = everyone, M = men, W = women, and 3 = me, myself, and I.</p>
<p>A lot of people are dubious about all-gender bathrooms before they get to Oberlin, and quickly find out that it’s just not a big deal. But there are also plenty of alternatives if it’s something you’re uncomfortable with.</p>
