There are many cosmetic things to do yet, and I need to put the toilet back in, but the half-bath has a working sink! Woo hoo!
It took four trips to Home Depot, and two trips to Ace Hardware. It’s been a while since I’ve done plumbing. The varying pipe sizes are bewildering. It’s all in working order now, though, and the rest of the bathroom should be exceedingly easy!
