Is each floor combined of girls and guys dorms?
Also, is the one bathroom on each floor for guys and girls to share?
I think it might depend on dorm, my memory is a little hazy, I personally didn’t pay too much attention. The floors in one of my dorms was definitely coed, but that was past freshman year, where you have your own bathrooms.
Maybe someone else can chime in, but I think the floors even in miller, the freshman dorm is coed, but the girls and guys are grouped together. IE , there will be 4-5 girls rooms bunched up, then the rest of the dudes.
When I went I stayed in the trees dorm and the floor was co-ed. There was a guys bathroom in the section I was in and to get to the girls bathroom you hd to walk to a different section of trees.
@businessg21 Ah yes, the famous “tree” dorms. 
My D is a current freshman. Her floor is single sex but others are coed. It’s just the luck of the draw. The floor above her is coed. They apparently had more freshman this year so things got changed around somewhat to other years. Bathrooms are single sexed from what she has told me, but each floor in her building (Trees) has 1 unisex toilet separate from the bathroom. Hope that helps.
