Almost perfect

Well, things went fast again this morning -- I was 100% certain I would need 10-20 trips to the hardware store and lots of weird adapters, but after some careful thinking and eyeballing, I got it all installed without any extras or trips to the store, and without any problems!*

The final step before hookup was assembling and mounting the faucet. Easy, peasy:

And here is the final hookup, in all its glory. Water goes in, water goes out, it all works just like it should!*

It's so, so... beautiful!

* There was in fact, one annoying problem that has to be taken care of. The last time I hooked up a sink, this same thing happened. The angle valves are those guys that stick out of the wall and have the shutoff valves on them. They don't last forever, even if you never turn them on and off. And when I turned the cold water valve (the one of the right side there) back on, it felt a little wonky, and it is now, very slowly, very gently, leaking. So to the hardware store I go, and then I will need to replace the angle valve, which is not super hard, but not super easy, either (unlike everything I just did, for this one you have to shut off the main water to the building). 

** Sadly, we've been reduced to calling a plumber. I *cannot* remove the old angle valve (I mean after 100-120 turns, several sets of me working until I was red in the face and sweating and shaking). It twists, but never loosens.
