I would just mask the toilet off. As for the toilet paper holder. I would do this: Rip it out of the wall. Then bitch at Ken about how he took your screw driver, left you to do it by yourself, and how the weather was bad so you couldent go out there (make sure to blame him for the bad weather too).
Seriously just rip the thing out. The screw is probably held in there by one of those nylon guides (cant think of the name of it right now). And always remember: when in doubt get a hammer.
