I was a taking a shower a few days ago (I've taken them since!), and I noticed what looked like mildew in the grout lines. Admittedly, I'd noticed them before, and bought some extra heavy duty tub and tile cleaner. But this time I stuck a fingernail in the grout line...

I think these are actually places where the grout is beginning to fail. Morelike, has already failed. There's quite a few of them. My other guess was that perhaps there was a darker grout to begin with and someone decided to regrout in white. The floor looks like maybe it was a darker grout, not just stained. (We're clean people-- I swear!).
So I'm thinking-- and correct me if I'm going about this all wrong-- I'm going to clean the grout in the tub/shower and walls well with a soft brush and regrout. The sticking point is that it's the whole bathroom's wainscoting, but I think that if I just pay special attention to the areas of failure and do the entire thing with the same batch using a good float, then I should be good, right?
Then I noticed this:

That's the hot water knob in the tub. And that black thing you see is a hole. Bondo and some chrome paint? I know I should just replace them, but I LOVE these knobs. The hole is on the backside and they're perfectly vintage for the rest of the bathroom...Or can you buy those sleeve things separately?
Then, there's the crack between shower and window:

Trust-- the first thing I want to do in this joint is paint the trim. The most recent paint job was done with FLAT paint. Sigh. Dirty fingers galore. However, you'll see that the first thing I ought to do, is address the "why you shouldn't just grout your tile to wood" issue. Clean it out and caulk it, I assume.
An finally, the real crack in the ceiling that haunts me daily:

The AC guys did this and offered to knock a few hundred dollars off the total if I let it go. I was fresh off the kitchen drywalling, so I thought this was the bargain of the century and a good opportunity to practice my texturing. I'm not so worried about the texture as I am about the sheetrock falling down. I think my plan is to perhaps put a couple of drywall screws into the portions that are sagging-- there's plaster with lathe underneath, so it's something for the screws to go into, and they don't have to hold the weight of the whole sheet; just the little saggy bits. Then tape and mud and patch as otherwise.
It's a little daunting, but should be a good trial run for repairing and successfully cammoflaging the, ahem, canyon in our other ceiling:
This weekend was a bit of a dud, so we've promised ourselves greater progress next weekend. We want that final inspection and we want it now. Or at least before the permit is a year old. Yikes.
*After the last 10 days, politically speaking, I feel I need humor more than ever. I'm getting a little worried.
