Hi, r/DIY! I am having trouble identifying this dumb thing on my bathroom wall: Nipple-like metal thing on my wall . I can't find anything about it on the internet. Does anyone know what this is? There's two of them, same height on the wall but about 16 inches apart and right above the toilet. I want to be sure they're not important before I rip them out of the wall.They're about 2 inches wide. I hammered the one on the left a little loose, and now it can spin around in a circle when I turn it, and I know if I give it some good force it will come out. Before I do that I want to make sure I'm not going to rip out any plumbing with it lol. Thanks in advance via /r/DIY http://bit.ly/2EUYHO8
