How To Change A Bathroom Faucet

How To Change A Bathroom Faucet

Changing a leaky or outdated bathroom faucet can seem daunting, but it’s actually a straightforward DIY project that we can tackle in an afternoon. With some basic tools and a little know-how, we’ll have that new faucet installed and be well on our way to updating our bathroom’s look.

In this guide, we’ll walk through the key steps to remove our old faucet and install a new one. We’ll cover what type of faucet to choose, how to remove supply lines and shut off valves, using faucet holes or installing on a sink with no holes, securing connections, and testing for leaks. Let’s get started!

Choosing the New Faucet

The first step is selecting the right type of new faucet for our bathroom sink. The main options are widespread and single-hole models.

  • Widespread faucets have three separate components—the hot/cold handles and the spout. They require three holes with 2 to 8 inches between them.
  • Single-hole faucets have the handles and spout in one piece. These only need one hole for installation.

We’ll also want to choose a faucet finish that matches our bathroom’s decor, like brushed nickel, chrome, bronze, or matte black. When choosing, it helps to bring measurements of the sink and faucet holes. This allows us to select a faucet that aligns properly. With measurements in hand, we can browse bathroom faucets at home improvement stores or order options online.

Removing the Old Faucet

Before installing the new faucet, we need to remove the current one. Start by shutting off the water supply lines under the sink or the home’s main water supply. This prevents water from spurting out when we disconnect hoses. Place a bucket under the faucet to catch any leftover water too.

Next, we’ll disconnect the supply lines and P-traps that link to the faucet. Unscrew the nut connections by hand or with pliers or a basin wrench. Place rags around these connections to soak up drips.

With the supply lines and drains detached, we can now take out the faucet. Carefully unscrew any remaining nuts or screws securing it from above and wiggle it free. Remove any sealant, putty, or existing rubber washers. We want a clean foundation for the new faucet.

Preparing the Sink

With the old faucet out, it’s time to prepare the sink for installation. Start by cleaning the faucet holes with rubbing alcohol to remove grime and mineral deposits. If our bathroom sink doesn’t have pre-drilled holes, skip to the section below on “Installing on a Sink with No Holes.”

For a sink with standard faucet holes, check that they align with the configuration of our selected faucet, such as widespread or single hole. We may need to enlarge the holes slightly using a spade bit attached to an electric drill. Go slowly to avoid cracks.

The distance between holes is also key for proper faucet alignment. Place the main faucet piece in position on the sink to test the spacing. There should be no gaps with all faucet parts sitting flush to the sink.

Installing Supply Lines

With clean holes cleared and our new faucet nearby, we’re ready for installation. There are just a few key connections to make:

  1. Water Supply Lines: Attach flexible copper tubing or braided steel supply lines to connect the faucet with the main bathroom water supply. Hand tighten connections before finishing with a wrench.
  2. Drain Attachments: Secure the faucet’s drain by sealing the flange edges to the sink using plumber’s putty or caulk. This prevents leaks from water flowing down the drain. Tighten the flange in place with a locking nut beneath the sink.
  3. Anchoring the Faucet: Double check that any gaskets are properly in place before lowering the weighted faucet into position from above. Secure the base by tightening screws into the pre-drilled sink holes from below the counter.

Once secured, we’ll want to test water flow and check for drips before finishing up!

Leak Checks and Finishing Touches

After installing all connections, slowly turn the water supply back on and test for leaks at the water lines, faucet base, and drain. Tighten joints or adjust positioning if any moisture appears.

While the faucet housing should now be securely in place, there are still a few finishing touches:

  • Reinstall the sink P-trap that leads down to the drain pipe using an elbow fitting at an appropriate height.
  • Attach any accessory pieces like side sprayers, escutcheon plates, or soap dispensers.
  • If included, affix the faucet handles and test adjusting both hot and cold water.

And that’s it! With our leak checks complete, we can rest easy knowing our fancy new faucet is professionally installed. No more drips or outdated fixtures dragging down our dream bathroom!

Installing On a Sink With No Holes

If our chosen bathroom sink doesn’t have pre-drilled faucet holes, not to worry! We can still install a great new faucet with a few extra installation steps using a specialty drilling guide template:

  1. Measure to find the exact mid-point of the sink basin before aligning the template. Trace hole markings with a pencil.
  2. Drill pilot starter holes before using a larger faucet bit matching sink material type. Ceramic and porcelain need diamond-coated bits.
  3. Affix water supply lines and lift rod hole if needed, using provided hardware with the faucet kit and attachment instructions.

Take care when drilling to avoid cracks and chips to the sink basin. The template ensures properly aligned holes for a seamless faucet installation—even with no pre-existing drill points. Be sure to smooth all cut edges too for safe handling and a polished look.

Helpful Tools and Materials

Here is a handy checklist of supplies we’ll want to have on hand for tackling this faucet replacement project:

  • Adjustable wrenches
  • Plumber’s putty
  • Flashlight
  • Bucket
  • Basin wrench
  • Faucet kit (with supply lines, washers, etc.)
  • Plumber’s tape
  • Rag
  • Safety glasses & work gloves
  • Caulk/sealant

Safety Tips

When taking on any DIY plumbing project, it helps to keep safety top of mind too:

  • Turn off main water lines and drain pipes before disconnecting.
  • Use eye protection when altering sink holes.
  • Get help lifting large sink basins.
  • Set non-slip mats on wet floors.
  • Coil hoses neatly to avoid tripping risks.

Taking a moment to prep our workspace and don safety gear keeps accidents at bay. We’ll breeze through this faucet facelift safely and efficiently.

So don’t let an outdated faucet drain your bathroom’s style any longer! With these key steps for replacing and installing a fresh sink fixture, we can upgrade our space to match our dream home vision. It’s less hassle than expected, and we’ll reap the benefits of increased home value for years to come with up-to-date, drip-free fixtures.
