I looked around online but I'm really not sure. I don't think we have a flashlight and I have no idea if there's a drain trap, but I'm definitely not scraping everyone's nasty hair out of the drain. Is trying to plunge til something comes up/it becomes completely unblocked a good idea or not?
How much does a plumber visit usually cost for this kind of thing? (I'm in SoCal)
Basically, what should I do? xD;
