So close...

Forbo Marmoleum Click has been installed. We purchased it locally at M&Z Carpets. If you're local, we highly recommend M&Z. The subfloor is concrete, so we used a trial-on leveling compound to even out some spots here and there. I should add here that we neglected to order any Marmoleum trim when we placed our floor order, and the freight charges made it cost-prohibitive to order our needed T-Mold as a stand-alone from M& Z.  So...we found this great online store, CoolGreenStuf, that carried the exact T-Mold we needed at a reasonable price. We went with Floor Muffler as the underlay/vapor barrier -- found a great deal on it on ebay where a guy was selling a complete roll and some left-over from his project, which was just enough to cover our kitchen and this bathroom.

The Marmoleum install went fairly well, although it was some tight quarters in there as you can see. There are only nine full-size squares in the floor (out of approx. 20) -- so cutting and fitting was essentially all we did. Like any project, it will go a lot smoother the next time.

Just need my plumber-uncle to attach the cast-iron flange to the drain pipe (pouring molten lead into a half-inch gap is not exactly a DIY project) and we're ready for the toilet and sink install.

The long-awaited reveal will follow.
