Question: how much does it cost to put plumbing in a shed?
Answer: At $50 to $100 an hour, that brings the cost to $500 or more. And if you're looking to trick out your shed with a wet bar or convenient bathroom? Plumbing is an even more costly addition, starting at $1,000 to $1,500 just to run the supply and drain lines. Watch out for your local laws, too.
