Today, after our first antique shop with no luck, we stopped at one of my favorite home interior stores to pick up a few bathroom accessories ... it's near a Home Depot, and Scott suggested we walk over since that particular store is much larger than the one near our home, and carries a more extensive line of products.
It was there that we found our temporary solution to the vanity problem:

We love it, and with it's narrow cabinet base (only about 13") the sink will be a great fit in the 1/2 bath we have planned for the first floor ... a project that I'm not quite so excited about now that I've jumped in head first upstairs.
Our plan? Put this beautiful, and very inexpensive (comparatively) vanity/sink combo into the bathroom upstairs until we find the perfect antique that we neither settle on or rush into to only regret later.
So, look forward to seeing that in the space very soon, I just got word that I'll have another pair of hands helping soon ... my brother's. He'll get here Tuesday and stay for just about 2-weeks ... hopefully having his handy strength will benefit the process and speed things up a bit.
