Hooking up a shower or tub faucet isn't as difficult as you might think. So long as you're comfortable with accurately measuring, drilling, and working with copper pipe, this project is well within reach. We broke the installation process down into easy-to-follow steps for optimal ease. Expect to spend at least half a day installing a shower or bathtub faucet.
Before you begin, you'll want to install separate 3/4-inch lines to supply the shower. This extra step ensures good water pressure and protects the bather from temperature changes when another faucet is turned on or the toilet tank refills. You'll want to tap into the cold and hot water lines as close to the water heater as possible. If needed, move a stud to make room for the plumbing behind the tub.
You'll also want to choose the tub or shower faucet you're going to install. Follow the manufacturer's directions for plumbing the faucet. And, if your faucet does not have integrated shutoff valves, install shutoff valves in the lines to the valve. For optimal comfort, position the faucet about 28 inches above the floor for a tub, and about 48 inches for a shower.
