I kept a Japanese Peace Lily on my bathroom windowsill in Scotland for a few years. Never watered it once. It thrived, and survived entirely on shower-steam (presumably condensing on the leaves/pot/soil). They're pretty resilient plants to keep, the way the leaves start to droop when they need watering makes it really easy to take care of them, even for people without particular plant-skills.
