How To Install A One Hole Faucet In Your Bathroom Sink

Your bathroom remodel has been going perfectly so far. You've managed to replace several bathroom accessories such as your mirrors, towel racks, and shower curtains. However, there's still one fixture that you just can't seem to figure out how to replace—your three hole faucet. Although your three hole faucet still works, it just doesn't provide the simplicity or minimalistic appearance of a one hole faucet. Here's how to replace it:

Remove Your Existing Faucet

Before you purchase a replacement faucet, you'll need to remove your existing faucet to measure the diameter of your sink holes.

Begin by shutting off your faucet's water supply and placing a drain pan underneath your sink. Disconnect the water lines to your faucet using a pipe wrench and drop the lines into your pan to avoid spilling the remaining water in the lines. With these lines removed, you can now use your wrench to remove the nuts that secure your faucet to your sink.

Once this is done, you can measure your sink holes and find a suitable one hole faucet for your sink.

Prepare Your Sink

You'll need to remove any remaining putty or waterproof caulking left behind by your old faucet before you can install your new one. Use an old sponge and a chemical cleaner to remove the putty or caulking—along with any mildew that grew underneath your old faucet's decorative plate.

Install Your Mounting Hardware

Your new faucet will come with mounting hardware and a stopper assembly. Begin your installation by filling the groove underneath your putty plate with a thick bead of plumber's putty. Press the plate over your sink holes and then place your decorative cover over the putty plate. Next, slide your faucet through the hole in your decorative cover and secure it by attaching your locking nut to the bottom of your faucet.

Install Your Stopper Assembly

The stopper in your sink must be connected to your faucet's lift rod to function properly. However, every manufacturer uses a proprietary stopper assembly that will require a certain installation method. Unless you're able to figure out how to connect the stopper assembly by yourself, you'll need to refer to your owner's manual for installation instructions.

With most faucets, you'll need to attach a specialized pipe underneath your sink drain and guide the stopper's pivot rod into the pipe—where it can connect to your pop-up stopper. While installing your drain pipe, make sure to place a bead of putty underneath your sink ring to prevent leaks. You can then attach the pivot rod to your faucet's lift rod with a bolt and nut.

Connect Your Water Lines And Test Your Work

With your faucet and stopper assembly installed, you can now connect your hot and cold water lines to the corresponding lines leading out of your faucet. To avoid leaks, place six to ten wraps of plumber's tape around the threading on your lines before connecting them.

Once your lines are connected, turn on your faucet's water supply and activate both the hot and cold water lines by turning your faucet's lever to the left and right. To make sure that your faucet's putty plate created a watertight seal, splash water around the base of your faucet and look underneath your sink for leaks. If there aren't any leaks, then you're in luck—you're finally finished with your bathroom renovation.

However, if there are leaks beneath your sink, you'll need to disconnect your water lines and place more putty underneath your putty plate. If necessary, you can use a caulking gun to apply waterproof caulking around the base of your faucet to eliminate the possibility of future leaks.

If you encounter any problems while replacing your faucet, then stop and contact a plumber, at a site like, to finish the job for you. If you continue replacing your faucet without knowing exactly what to do, you may damage your new faucet or your sink.

Home Renovation Expectations: Knowing What's To Come

When I bought my first house, I did it with the expectation of needing to do some remodeling. I wasn't, however, prepared for how complex the renovation process was. From upgrading the retaining walls to adding cosmetic features like the stone patio, I was inundated with decisions to make and materials to select. I wished that I had known how much was involved from the beginning so that I could be better prepared. That's when I decided to use what I'd learned to help others better prepare for their own remodeling projects. I hope the information here helps you to see what you can expect as you get ready to expand your property or renovate the existing space.
