@Lilliana330 not necessarily. There is a great deal of discussion about that on these forums. For example:
In my dorm in the 70’s, every other room was male or female (i.e., the rooms on each side of mine were male, on each side of a male were female, etc.), every floor, and all bathrooms were coed. Though the level of integration may differ, coed dorms are so not new.
I honestly don’t care. I imagine that, as in most things in life, there are pros and cons to each situation. If my daughter had a strong opinion one way or another, I would honor it. But, I think my daughter is more interested in the “vibe” of the dorms than the gender of the people who live with her.
ETA: Do people not have opposite-gender siblings anymore? Wouldn’t these opposite-gender siblings have had their friends hanging out and sleeping over at the house all these years? I would think most kids are used to being around kids of all types by the time they leave for college.
There are no single sexed dorms on my daughter’s campus. No hall baths either- only suites and apartments. All suites are single sexed. Co-ed is the norm these days. Is the co-ed dorm hall bath or suite styled?
My D is in a co-ed dorm. There are 2 boys that live in the room right next to theirs and another 2 a few doors down. They have their own specific bathrooms. They all tend to hang out in the lounge together and doesn’t seem to be any issues or complaints. Every entry point in their dorm is card reader access so its pretty secure as to who can go into what rooms. Seems to be working out well.
S decided to sign up for gender-inclusive housing at his school. There was a long list of awareness items that he had to agree to, such as learning and using his roommates’ preferred pronouns. The dorms are suite-style, three single bedrooms with a shower room, toilet room, and three open-area sinks in each suite. Students have to specifically sign up for gender-inclusive suites, otherwise housing is co-ed by suite. His school doesn’t have any single-gender dorm buildings.
When I went to college in the mid-90s I lived in a dorm that was co-ed by wing, with the central elevator lobby separating the two wings and one large shared bathroom in each wing. The doors from the elevator lobby into the living areas were never locked, and were usually propped open. Due to the placement of the bathrooms and the propped-open lobby doors everyone was used to seeing people of the opposite gender going to/from the bathrooms in towels or their underwear. It was no big deal.
I lived in coed dorms in the 1970s. And yes we had coed bathrooms too. Later at the same college I lived in suites with their own bathrooms. Both were fine. My boys lived in coed dorms as well. The older son had a suite arrangement. Younger son the dorm had single sex wings. I got the impression that they pretty much kept the bathrooms single sex.
My DD2016, thru luck (or unluck) of the draw was placed in an all girl dorm her freshman year. She was NOT happy with the placement, she has always had more guy friends than girls and hates “girl drama”, so I too was worried about the all girl dorm. However, 3 weeks into freshman year she declared it to be fine and by the end of the year was actually considering living there for sophomore year; as it was deemed quieter, nicer and most conveniently located.
Ultimately, she was placed in a coed by floor dorm for sophomore year. She hasn’t said anything about it, one way or the other. Frankly, she doesn’t socialize much with her dormmates, her friend are from classes and clubs mostly. She met plenty of boys despite living in the all girl’s dorm and found a boyfriend mid fall freshman year who spent lots of time in her room, I imagine. This year he is living on the floor above her in the coed dorm, which I imagine would be slightly more convenient for them, lol.
Next year DD will be in an apartment, she asked if she could have male apartment mates (not the BF, just male friends). I was fine with it, she will be 21, as long as the rent gets paid and her apartment mates are not convicted felons, it’s all good, alas her other female roomie’s parents put a quash on male roomies.

I think it might come down to respect. What comes to mind as a fear is summer camp, high school locker rooms and peepers, etc. I would hope that college students are more mature than that. I would have a problem with a co-ed bathroom that is like a locker room? You know, shower curtains, benches, etc. I suspect that is not what they are these days.
I guess I actually need to walk into one on the next tour. Funny, but we’ve toured a dozen schools, and I haven’t looked. We REALLY like the suite style.
Sure, my male and female kids share a bathroom, but there is a door with a lock and they don’t walk down the hallway half dressed. I envision that what @traveler98 described could be an issue for someone who is modest. (the open door, scantily clad bathers)
Even women’s colleges for the most part allow men to stay over in the dorms.
Throughout DD16 college search dorm and bathroom situation somehow never was discussed. Her first semester she was in a triple in a large co-ed suite. They had two bathrooms with multiple stoles and showers. Never been a problem. This year she is in a single in a small coed suite with a single bathroom. Again I have never heard any complaints. For next year she plans a move to a different side of campus which is a huge deal for her because different sides have completely different culture. She plans to move to a suite with her 3 guy friends. Each of them will have a single. For her much more important issue is to live in a non partying suite. Friends she will be living with next year don’t drink at all for religious or some other reasons.
I lived in a co-ed dorm. My children live in a co-ed dorm. This is pretty much the norm.
My parents never thought to ask about the dorm or bathroom situation. Neither did I.
I’ve shared a house and bathroom with men and women for my entire life- related and unrelated- so I never much cared what was in the pants of the people I was living with
Double post
@tutumom2001 On the sibling issue - just a funny thing I never would have thought about – I am remarried and I have 3 girls, my husband has 1 girl and 1 boy and they are all about the same age give or take.
My girls were so used to just actively sharing the bathroom – meaning if someone was showering for example and you needed to brush your teeth you just did - a quick know hey and that was that for my girls. My stepdaughter was not and even though she now shared with almost all girls (excepting her own brother) she was horrified that ANYONE would come into the bathroom or even ask to when she was in the shower.
And my girls thought it a tad odd that my stepson would walk around the house holding a towel on himself only before and after a shower (his room was on the lower floor). It was a little funny to watch them all adjust over time.
@labegg - I was also placed as a freshman in all girls, and ended up really liking it. I went down to breakfast in sweats, ran down to the laundry in a robe or whatever and never felt like I had to worry about where were the guys and how did I look lol?
My daughter freely runs around in sweats and a robe in coed situations with zero thought about what guys think. Guys really have no issues with girls in sweats and no makeup. 
Another Co-ed dorm floor here. We did share a bathroom so showering with a naked girl in the next stall was definatley a new experience for me. There were never any problems. We all watched out for each other and it was a family dynamic - brothers and sisters. I think it was a great idea on the schools part. The girls always had a guy available if she felt she needed some escorting (not to set off the woman here but some felt more comfortable walking late at night with a guy. just saying). It also taught everyone respect for the other sex.
I’m pleasantly surprised at the number of replies. As I understand it, my D’s dorm would have suites, in which each suite is initially assigned to a single gender with a bathroom in the suite, but alternating suites can also alternate genders on the same floor. An operating term is “assigned.” Apparently, students can spend days and nights in other suites as long as the roommates are agreeable and no one complains, which can result in mixed genders sharing beds and bathrooms, or even swapping their room assignment. Some comments in some older threads that I had read complained about loud and nightly romantic activities. It is nice to hear these positive comments about co-ed dorms.
Same.
S and D both lived in coed dorms with both single sex and coed bathrooms. It seemed like the large main shower/baths were male or female, and the smaller ones coed. You use the closest one, or the one you feel more comfortable in.
Everyone heads back to the room with a towel or robe on.
This was my experience too.
