There's more to it than this. Your own bathroom is private, so you don't have to worry about going in there and there not being any stalls. You don't have to sit on the pot while someone else is right next to you, separated only by a flimsy partition where you can see their feet. You don't have to smell other peoples' crap odors. You don't have to use shitty one-ply sandpaper-ish toilet paper. You can install whatever toilet you like, instead of having to use whatever is there; you can even install a bidet if you want. You can keep it as clean as you like. You don't have to worry about someone else peeing on the toilet lid or smearing their crap on it. You can dry your hands with a real towel, instead of shitty sandpaper-ish brown paper. Your house might have a bathroom fan installed. You can set the temperature however you like. I really, really, really hate the bathroom at my current workplace.
