In my basement I have a utility sink with threaded faucet and an open drain underneath. There are hoses hanging on the wall right next to the sink. I'm thinking about giving it a shot, though I'm not sure what the landlord will think (my first winter in this place, landlord seems laid-back, but might be upset none-the-less)... The floors don't appear to be sloped toward the drain (looks like it is mostly just meant the washing machine and sink to drain into). The floors are concrete, so a bit of water probably won't be the end of the world...
