Step-by-Step Guide

Turn off the water supply to the bathtub. There will be two valves under the sink, one for hot water and one for cold water. Turn both valves to the "off" position.
Remove the old bathtub faucet. Use an adjustable wrench to loosen the nuts that hold the faucet in place. Once the nuts are loose, you can remove the faucet by hand.
Clean the bathtub valve seat. The bathtub valve seat is the area where the new valve will be installed. Use a scrub brush and some cleaning solution to remove any dirt or debris from the valve seat.
Apply plumber's putty to the new valve. Apply a ring of plumber's putty around the base of the new valve. The plumber's putty will help to seal the valve and prevent leaks.
Install the new bathtub valve. Place the new valve in the bathtub valve seat and hand-tighten the nuts. You can then use an adjustable wrench to tighten the nuts until they are snug.
Connect the water supply lines to the new valve. Use a wrench to loosen the nuts on the water supply lines. Once the nuts are loose, you can remove the old water supply lines. Install the new water supply lines by connecting them to the new valve and tightening the nuts.
Test the new bathtub valve. Turn on the water supply to the bathtub and check for leaks. If there are no leaks, the valve is installed correctly.

Additional Tips

If you're not comfortable working with plumbing, you can hire a plumber to replace the bathtub valve for you.
Be sure to choose a new bathtub valve that is compatible with your bathtub fixture.
When tightening the nuts on the water supply lines, be careful not to over-tighten them. This could damage the valve or the water supply lines.
