Bathroom Reno Day 21ish

Suffice it to say, the renovation is almost done but I've been at work so the time I spend on this is sporadic at best. I ditched out a bit early today and then ran to HD to get a few different things, including some granite sealer for the vanity top ($40 for a small bottle, can you believe that?!?), some electrical tape, and the baseboards and chair rail . I got one baseboard piece in, as pictured above, and then I realized I was going to have to cope. I've mitered before but never coped. I watched a few videos, read some stuff online and in books, and, honestly, I still am kind of clueless about this. I'll go get a coping saw tomorrow and give it a shot. I only have about 12 angles to cope for the baseboard and two for the chair rail. Ick.
Then, despite my vicious bitterness about it, I cut up some old drywall left from our kitchen renovation and put it up around the tub surround. I hate, hate, hate having drywalling but it's done now. I need to figure out what I'm going to do about the corners, however. I hate corner bead - I was thinking about getting some outside corner moulding but I'm not sure how that will fly. Other ideas?

In other news, I was really hoping to replicate the window and door casing that we have in the rest of the upstairs but it seems pretty complicated. Also, I'm not sure how it will look with the little dinky window we have in there (it's one of those crank-out kind). I might just suck it up and buy something basic at HD but I don't want the plain casing we had in there before.

So, tomorrow, I'll put another layer of mud on the joints and on the ceiling of the tub area. I'll go get a coping saw and figure out how to do the dumb thing, and then I'll work on the door casings, try to get the baseboards done as well as the chair rail. It would be nice to paint on Sunday and then maybe get the lights up. We'll see, I guess.
