Replacing your tub spout is a simple home improvement project requiring only a few tools and materials. Make sure you purchase the right spout.
Tub spouts come in two basic types: screw-on and set-mounted. Check underneath your spout. If there’s a hole in the bottom, it’s a screw-on. If it fits snuggly against the wall, it’s a set-mount.
Tools and Materials
Tub spout
Pipe compound
Silicone caulk
Small screwdriver or Allen Wrench
Water-pump pliers
Rags or towels
Step 1. Disconnect the old spout. Check under the spout to see if there’s a setscrew. If so, loosen and slide it off the spout. If there’s no setscrew, use a pipe wrench to unscrew the spout from the threaded pipe. Be careful not to twist too tightly because you can damage the spout nipple, especially if it’s made of copper. Liberally apply joint compound to the nipple thread.
Step 2. Install the new spout. Slide the new spout over the pipe. Make sure it’s snug to the wall. Tighten the screw. If it’s a threaded pipe, screw on the spout by hand. If it needs further tightening, put tape over the teeth of the water-pump pliers to prevent scratching and tighten until the spout is snug. 
Step 3. Run silicone caulk around the spout. Wipe off the excess. Make sure you allow the caulk to dry before using the new spout.
