I made props for public bathrooms. A toilet with walls and a door to poop in privacy. A mirror that you can place next to each other to enlarge the mirror surface. And for the men a pissoir.

I put the props in a DLC for single player. Just place the file in mods>x64>dlcpacks with OpenIV. Then edit following script: mods>update.rpf>common>data>dlclist.xml and a line with this DLC: dlcpacks:/addonprops/
