How to Replace a Leaky Bathtub Spout (Thread-on vs. Slip-on) · Step 6 of 6
In this video
To create a waterproof barrier, a generous bead of silicone caulk is applied around the copper pipe where it exits the shower wall. The chrome tub spout is then carefully slid onto the pipe until its base is flush against the wall, compressing the caulk. Finally, an Allen wrench is used to tighten the set screw located on the underside of the spout, locking it securely onto the copper pipe.

FAQs
What is the difference between a thread-on and slip-on bathtub spout?
A thread-on spout screws directly onto a threaded pipe nipple coming from the wall. A slip-on spout slides over a copper pipe and is secured with a set screw underneath. Check your existing spout type before buying a replacement.
How do I know if my bathtub spout is leaking from the diverter or the connection?
If water drips from the spout when the shower is running, the diverter is failing. If water leaks around where the spout meets the wall, the connection or seal needs attention. Both issues require removing the spout.
What tools do I need to replace a bathtub spout?
For most spout replacements, you will need a hex key or Allen wrench (for slip-on types), pipe wrench or adjustable pliers (for thread-on types), plumbers tape, and silicone caulk for sealing.
Can I replace a bathtub spout myself without calling a plumber?
Yes, this is typically a DIY-friendly project that takes about 30 minutes. The key is identifying your spout type first and having the right replacement part.
