How To Install a Widespread Faucet



A bath faucet that has handles separate from the spout is known as a widespread faucet. These are available in a wide selection of styles and prices. They can be installed with most any hole spacing.  Watch the video above to see how to complete each step in the installation process. Also, the 10 steps below provide additional information, as well as the tools and materials needed to complete this project.


Refer to the manufacturer’s instructions for the list of components, proper assembly, and maintenance of your new faucet. Keep in mind, a WaterSense-certified faucet will help save on water bills and reduce water use.

Step 1: Turn off the water

turn off the main water supply

Remove all items from under the sink. Place a bucket, pan or rags under the work area. Use heavy towels to support your body if you are reaching into the sink area and under or through the vanity.

Turn off the hot and cold water supply lines at the shut-off valves beneath the sink. If there are no shut-off valves, turn off the main water supply. This is a good time to install stop valves as part of this project so you can turn off the water easily in the future.


Turn the faucet on to release the pressure in the water lines.


Step 2: Remove the old faucet

Remove the old supply lines to remove the faucet

Be sure to wear safety glasses to protect your eyes from falling debris as you work upside down under the sink.


Remove the old supply lines and the mounting nuts to remove the faucet. Apply a penetrating lubricant if the lines or nuts are corroded or in a hard-to-reach position. Do not use strong force to remove them – be gentle yet persistent.

Lift the faucet fixture from the top of the sink. A putty knife can remove all of the old sealant from the top. Use a cleaner suitable for your sink type to clean the area.


Step 3: Seal the spout base

 Seal the base of the spout Form plumber’s putty into a rope and place it on the base of the spout. Press the putty against the base. Set the spout into place.

Step 4: Hand-tighten the basin nut

Tighten the nut just to hold it in place Tighten the nut just enough to hold it in place. Do not overtighten the nut because you will need to first center the spout on the sink.

Step 5: Thread the tee on the spout

Center the tee to line up with the faucets Center the tee so the outlets are approximately parallel to the back wall and line up with the faucets on either side.

Step 6: Center the spout

Tighten the spout using a basin wrench Once it is centered, tighten the spout from beneath the sink using a basin wrench.

Step 7: Place the faucet valves in the sink

Slide the washer beneath the sink Slide the washer over the threads from beneath the sink. Tighten the valve nut until snug.

Step 8: Connect the faucet valve lines to the faucet valve

Apply pipe compound or Teflon tape to the threads of the valve line Apply pipe compound or Teflon tape to the threads of the valve line. Connect to the faucet valve, and hand-tighten. Apply pipe compound or Teflon tape to the other end of the valve line and hand-tighten onto the spout tee.

Step 9: Finish the assembly and tighten the connections

Assemble water supplies and tighten the connections

Apply pipe compound or Teflon tape to the threads of the water supply tailpieces and connect the hot and cold water supplies to the hot and cold supply valves. When the entire assembly is complete, go back and tighten all the connections with an adjustable wrench.

The last step is to connect the faucet handles to the valves. Align the handles to the “off” position. Apply a bead of plumber’s putty to the faucet handle base, attach the handle, center it, and tighten the faucet nut below the sink with a basin wrench.


Step 10: Connect the water supply lines and check for leaks

Turn the water back on at the shut-off valves

Turn the water back on at the shut-off valves. Turn on the faucet and allow both hot and cold water to run for one minute. Check for leaks.

Install the matching pop-up drain (if supplied) with your new faucet.
