There’s nothing quite like a nice warm shower or bath. Sometimes, though, bathtub faucets are fickle. Whether it’s leaking, slow, not diverting properly, or dated, you may need to replace the faucet. There are two common faucet types and installation methods, so it’s not as easy as just going to the store to get a new one. Don’t worry, though. In today’s guide, we’ll go over how to replace a bathtub faucet.
Getting Started
First, you need to sort out what kind of spout you have. There are two common tub spouts. The first and most common spout is a threaded spout. Next up, you have a slip-on spout, and this is the easiest to install.
Here’s a list of tools and supplies you’ll need to get the job done:
-
Screwdriver
-
Allen wrench
-
Drain stopper
-
Bathtub faucet
-
Adjustable wrench
-
Silicone caulk and gun
How To Replace A Threaded Bathtub Faucet
Step 1
First, you need to remove the old faucet. The best way to do this is to wrap the existing faucet with a cabinet liner and use a wrench to unscrew it counterclockwise. The liner acts as a protective and grip layer to make removing the faucet easier.
Once the faucet is off, inspect the pipe. You need to note where the threads are located and how long the pipe is so you don’t have to buy an adapter. Some threads are at the back of the pipe, but most are at the end. Whichever it is, it’s best to take measurements and photos with you to the hardware or plumbing supply store.
Step 2
One of the most important steps is to wrap the pipe with plumber’s tape. For the best seal, wrap the threads four times, clockwise.
Step 3
Next, screw the new faucet onto the pipe. Ensure the threads match up so you don’t accidentally cross-thread.
Step 4
Finally, apply a thick bead of silicone caulk around the base of the faucet to prevent water from getting behind the spout and into the wall.
Pro tip: use a wet finger to smooth silicone caulk to prevent getting it all over your hands.
How To Replace A Slip-On Faucet
Step 1
To remove a slip-on faucet, the most important thing to do is remove the set screw. If you don’t remove the set screw first, you risk damaging the pipe or plumbing in the wall. Depending on the model of the bathtub faucet, you may need an Allen wrench or Phillips screwdriver.
Before you do anything, though, put a drain stopper over the drain. The last thing you want is to drop the set screw down the drain.
Step 2
When the set screw is off, pull the faucet off. You may want to use a wrench to turn the faucet and pull it off easier.
Step 3
If the pipe has any rough spots or grime, clean it off with medium-grit sandpaper first. Then, install the new faucet and make sure to tighten the set screw.
Step 4
As with the threaded spout, make sure to caulk the gap between the wall and the faucet.
