My shower has recently been having trouble draining and, with a flashlight, I've noticed that there's a great deal of hair and other material stuck in the pipe, clogging it. It seems simple enough to remove the clog, if only I were able to first remove the drain cover.
It appears that the cover is cemented in place and I can't find any hints on how to properly remove it. I tried using pliers to grab it and either twist it out or pull it, but it's definitely not coming out.
Is there something I'm missing? Is there a way to remove it easily? Or should I just force it out, possibly breaking it in the process (it's already cracked, as you can see in the picture)? What sort of replacement should I look for, and how do I install it?
