Well, we waited and waited and the blotchiness never went away (you can kind of see it here). We tried to get the guy back, but never could track him down. Finally, just when I was about to give up and have our brand new tiled shower and floors just look like dirty old ones, a guy on the crew that had been working on the rest of the renovation came in, scraped out all of the grout, and re-did the entire space (and the angels sang, taa daaaaaa).
