First of all, you will have to replace the faucet handle. In general, the bathtub faucet handle is attached and kept in place with the help of screws.
To replace the bathtub faucet stem, you will have to replace the faucet handle first. If you examine the faucet handles carefully, you will find the set screw that holds the handles in place. In case, you don’t find any setscrew, try locating the faceplate that should be in the middle of the handle.

Once you have located it, gently pry up the small faceplate from the handle using a flat-head screwdriver. Then, you can remove the screw with the help of a bathtub handle extractor or by using a screwdriver. You should turn the screwdriver counterclockwise to remove the screw.
Hopefully, you have successfully removed the screw. Now, pull the handle toward you to remove it. It may require waggling the handle back and forth gently to remove the handle. Sometimes the handle gets attached to the plumbing due to hard water build-ups like calcium and magnesium. If you have such a condition, try tapping the handle with a hammer. This will loosen the calcified material and remove them. As a result, the faucet will come out smoothly.
At this moment, you need to attend to the bathtub faucet stem. Come back here again when you are done with it.
Now it is time to set the new handle in place of the old one. The handle has a female surface and it should match with the teeth on the plumbing. Properly place the screw and secure the handle properly in its place.

Bonus: Bring a new look into your bathroom
You have already stopped the drip of your bathtub faucet. Here is a bonus tip on how you can replace the bathtub spout and bring an exciting new look into your bathroom.
We are assuming that you are not happy with the current look of your bathroom. The good part is giving your bathroom an exciting new look is not very expensive or it does not require a lot of time. Replacing some items in your bathroom can bring a new life to it. You have already replaced the bathtub faucet stem and the handle. Here we will guide you on how to replace your bathtub stem.

A bathtub spout has multiple attachment methods. There are three widely used ways for a bathtub spout attachment. You will be glad to know that the replacement of a bathtub spout is very easy despite the method it follows for the installation. Moreover, you will be able to do it with the help of household tools and a plumber’s small pipe wrench. To affirm you, the replacement takes very little time.
Replace a bathtub faucet spout
As there are multiple ways the faucet spout might be attached, first of all, you need to figure this out. The three different ways of spout attachment are listed below:
- First of all, a screw-on spout with threads deep inside the spout
- Secondly, a screw-on spout with the threads at the back of the spout
- And, finally, a spout that requires a set screw underneath
Tools that you will require:
- Flat-head screwdriver
- Hammer
- Phillips screwdriver
- Allen wrench
- Small pipe wrench
- Soft cloth
You should note that the spouts that screw on won’t have a set screw. On the other hand, if it is equipped with a set screw, it should be on the bottom of the spout approximately 1/4 inch or it can also be further out from the wall. Moreover, you may need the help of an Allen wrench or Phillips screwdriver to work with the set screw. You will have to use the pipe wrench for the spouts that have a screw-on. Take a rag and place it over the spout and adjust the pipe wrench’s mouth. This will help fit over the spout so it locks into the position. Finally, turn the wrench counterclockwise.
You will find another type of spout that is attached at the bottom with the help of a set screw. Remove the screw and you are done. Some spouts are installed with a set screw underneath the spout. You need to be careful both when removing and also while installing the set screw for the spout. Gently screw the threaded tub spout to ensure that you don’t ruin or cross-thread the threads inside. It is better to go slowly and if you find any resistance, you will have to back out the spout and re-thread it again. Try to manually tighten it as much as you can.
Before you go for the final tightening, it is better if you wrap the threaded tub spout with a rag. Most importantly, make sure the spout is properly aligned.
Important note
Never try to over-tighten the tub spout. If you have a tub equipped with both hot and cold water lines, you need to look under the handle for the setscrew because this is how it is kept in place. To be on the safe side, use Phillips screwdrivers for cross-headed screw heads. Additionally, when you go to the store for replacement parts it is better if you take the old one with you. In that case, you will have to remove the old ones first.
