It's not that simple.

Building a bunch of family stalls costs a lot more than simply building a women and men's room.

Aye at least in Ireland there are no unisex bathrooms which have urinals (which are a massive way to save money in construction and maintanence), could be that they exist in other countries but I would think that they would at least require a little extra work to give some privacy to the guys and of course not every woman would be as comfortable with guys taking their dicks out to piss in front of them... I'm not sure anyone would want to use a bathroom like that if there was a chance young girls could walk in... or I doubt parents of said young children would want them using the bathrooms either.

And that's why we shouldn't have gender neutral bathrooms.

Only a small percentage of the population's gender doesn't correspond with their sex. 

Besides, urinals are the reason why a man can go in and out of the bathroom in one minute(or 20 seconds if you're disgusting and don't wash your hands). In general though, I've realized that men typically use the bathroom much quicker. Maybe it's because men don't have as much to clean(?) 

Unless 20+ percent of the population is transgender, I don't really see the need for gender neutral bathrooms at all. Save time and money by making two bathrooms, one designed for men, the other for women

I work in Austin, TX, and it's getting a little silly now.

To catch anyone up: Austin is a very liberal city, often cited as a blue oasis in a red desert. And nearly every place in Austin has replaced their Men and Women signs with Men/Women signs. I keep thinking "Okay, there's the family room for people with infants and toddlers... And there's another... Wait."

It gets even more ridiculous when they tried using unique ways to determine men and women's rooms, like with art and such on the doors. Overall, it makes finding a urinal difficult.

I would prefer different signs that at least indicate which room has urinals. Seriously.

Does that mean that both types of bathroom include that rather nasty bin for sanitary towels? Since obviously a woman in a mens bathroom isn't going to flush that right? for me that is one of the reasons that I also wouldn't want to be in a unisex bathroom, heck maybe if you find that inside the bathroom you go in you could just pop the lid open and you got yourself a urinal?

And sure it's all fine to say people should be mature about it and able to use the same toilet as everyone else without feeling awkward, but do you think the same about your children? would you let a small girl walk into a room after some big guys to use the bathroom knowing that the guys might be using the urinal inside?

I was a janitor out of high school. Many women think you're supposed to flush them away (pro-tip if you're a girl who thinks you can flush it, NO YOU CANNOT, IT IS A SUPER ABSORBANT PIECE OF SPONGE, IT WILL INFLATE AND CLOG THE TOILET OMFG).
