1
Prep the Project

Gather your tools. You’ll need pliers, hex wrenches, joint compound and a screwdriver. Turn off the water. Open the faucet so all the water can drain out of the spout. Gently remove any caulk sealing the old spout to the wall.

Tip: Once you remove the old spout, examine it carefully. It’s easiest and quickest to install a new fixture in the same type and size.

Unscrew the Old Tub Spout

Most faucets screw onto a threaded pipe or are attached with a set screw. Check under the spout to see if there’s a set screw. If so, loosen and slide it off the spout. If the set screw is tight, try prying it out with a screwdriver.

If there’s no set screw, use a pipe wrench or pliers to unscrew the spout from the threaded pipe. Depending on how tightly the spout is screwed on you may have to use a fair amount of pressure.

Install the New Spout

Unpack your new spout. Next, liberally apply joint compound to the existing pipe thread. Slide the new spout over the pipe, making sure it’s snug to the wall, and tighten the set crew. 


If it’s a threaded pipe, screw on the spout by hand or use pliers. If your new tub spout needs further tightening, put tape over the teeth of the water-pump pliers. This will prevent scratching. Tighten until the spout is snug.

Caulk Around Tub Spout

Run silicone caulk around where the spout touches the wall, wiping off the excess. Allow the caulk to dry before turning the water back on and using the new spout.

Installing on a Tile Wall

Installing a similar size and type tub spout can be accomplished using the steps above on both solid surfaces and tile. However, if you’re replacing a tub spout on tile with a different type fixture, you may need to cut the tile. 


Measure and draw a cut line for your new faucet. Use a rotating tool or jigsaw with a tile blade to gently cut your tile in 1/4-inch depths until you cut through. Be careful not to crack your surrounding tile. Install your new fixture following the manufacturer's directions.

Replacing your old tub spout is a quick update you can do in just a few hours. All you need to do is remove your old faucet and slide on your new one. Find a new style faucet or the tools you need at The Home Depot. We deliver online orders when and where you need them.
