Here's a picture, at last:
You can see how tight it is in there with the tub, but it fits and that's all that matters. In case anyone is interested, we went with a Samsung WA5471ABW/XAA top-loading washer (love the enormous capacity) and the matching DV5471AEW/XAA front-loading dryer. They have a smaller footprint than most of the fancy machines out there today, but they don't skimp on capacity and options.
If you're lucky, I might show you a bathroom or two tomorrow!
