I've got an old IKEA dresser that I was wanting to repurpose into an outdoor, hospital coop to be available to use when needed. I'd like to be able to do it with as little cost and effort possible. 
What needs to be done to water proof an indoor furniture item for outdoor use? Or, is it something that just cannot be done and I shouldn't waste my time and money and just buy some cheaper small coop?
Can you share any pictures of any of your repurposed coops?
