If your wife won't let you drill holes in the door of your fridge, I've found that a galvanized metal square gangbox works great for holding taps.
Something that looks a lot like this:
The pre-punched holes are the perfect size, and you can bolt the box to the bottom of a wire shelf with 1/4" bolts and a couple of washers.
I'd post a sweet picture, but I have to buy grain this month. Next month I'll put out for a membership.
