On average, you’re looking at $150 to $500 for labor alone. Yes, that’s just for the person with the wrench and the know-how.

But if you’re going full-on water wizard—like a whole-house system or a reverse osmosis setup—expect to pay $400 to $1,000+. That’s the price of a small vacation, minus the sunburn.
