In order to make the new sink fit, J. had to remove the "soap dish" which had been "installed". This is what lay underneath. So, on top of the sink, tile work was also required. (Yes, that is wood and rubble you are looking at.)
So, after four weekends, five trips to the hardware store, a new drill bit, and some choice words for the manufacturer of the cheapest sink that our big box home improvement store sells, we have a new sink....The bathroom is still ugly, but a little more functional. And we can turn off the water supply without running down two flights of stairs!
