Are they worth the money/hassle?
We are pretty skint, and we rent, but there is a space in the kitchen next to the washing machine (probably from a dryer, but that means there is plumbing nearby, right?). We could save up for a washing machine if it would stop the towers of washing up sitting there looking at us while we eat. The landlords are nice, so if it is simple I'm sure they won't mind us plumbing it in.
