Is the ability to have your own private bathroom. While I don't have a remote job yet, and I currently work as a security guard in a office building. I frequently hate it when I need to use the bathroom and someone already takes my stall that I was going to use. Then I have to go to a different floor only to find those stalls occupied as well. It is like a bunch of people decide to all take a crap at the same time on different floors. Plus, the smell and having your other co workers come in when you are in the bathroom is also annoying.
At home, my bathroom is right next to my room and me and my dad are the only one who uses it. Besides, my dad is gone most of the day and the bathroom is fairly clean. If I get a remote job this will be one of my favorite perks of working from home.
