I just took the time to re-read this from the start, it's a bit of mind blowing experience the way you have this thread set up.
Anyhow, just wanted to say:
1) Everything looks stellar, nice work so far!
2) Be careful about how you've drained your laundry tank. Since I gather you're not requiring permits (since it looks like this is getting installed in an already developed area of the house), this may be less of a concern for you than it was for me - but technically it is now against code to have a sink indirectly drain into a floor drain like that. I did for my tank room exactly as you've done and I failed the plumbing inspection. I had no drain line I could tie into on the wall so I had to jackhammer the concrete, cut the pipe for the floor drain and tie into that, and then pour new concrete down. And that was the easy part (!!) because the sink drain itself has to be vented so I had to run a line up into the ceiling and route that to the nearest drain vent up to the roof, and T into that. Well, maybe that wasn't harder than the jackhammering but it still took some creative head scratching trying to figure out how to vent that sink.
3) Lee Valley is awesome. I like the sink brackets instead of legs idea. I actually have to replace my sink as it developed a crack and now leaks onto the floor, so I might just go with the brackets for the replacement sink. I'm glad I didn't replace it out yet before catching up on your thread! So: thanks for the idea.
