Replacing a bathtub faucet is a relatively simple plumbing repair that can be completed in a few hours with the right tools and materials. The first step is to turn off the water supply to the faucet. This is typically done by closing the shut-off valves located under the sink. Once the water is turned off, you can begin removing the old faucet.
To remove the old faucet, you will need to use a wrench to loosen the nuts that hold it in place. Once the nuts are loosened, you can pull the faucet straight up to remove it from the sink. Be careful not to damage the sink or the countertop when removing the faucet.
