Thanks everyone! I was trying to get a barrel tap to be the faucet in the bathtub, but the half walls I used prevented me from placing any items in the tub. I wish I'd thought of it sooner (before I'd done too much to make it feasible to re-customize, take down the half wall, lock down a faucet, and rebuild the tub). That'll be the one thing that irks me about this house

Maybe next time... I'd like to try building some custom houses, on Test Center or something, but it's going to take some time to get inspired. I just love looking at the works of other people - even if some of the styles aren't my taste, I still marvel at all the talent that's out there! There are some very creative people playing this game.
