Converting to Single-Handle Faucets: A Practical Upgrade for Your Home

The world of faucets has evolved significantly over the years, and one of the most notable upgrades you can make to your home is switching from a two-handle faucet to a convenient single-handle faucet. Whether you’re looking to update your kitchen or bathroom, a single-handle faucet offers both style and functionality. In this blog post, we’ll guide you through the process of converting to single-handle faucets, discussing everything from the conversion process to the benefits and even how to fix a leaky faucet.

Why Make The Switch?

You might wonder why you should bother converting to a single-handle faucet. The answer lies in convenience, aesthetics, and efficiency. Single-handle faucets offer precise control over water temperature and flow with a single motion. This streamlined design also adds a modern touch to your kitchen or bathroom, instantly updating the space. Additionally, single-handle faucets are often more efficient, helping you save water and energy over time.

Making the switch from a traditional two-handle bathroom faucet to a modern single-handle design offers numerous compelling advantages, especially when considering the convenience and elegance it brings to your space. With a single-handle faucet, adjusting water temperature becomes effortless, while the streamlined one-hole faucet installation not only enhances the aesthetics of your master bath or new bathroom but also eliminates the clutter of extra handles. The availability of these faucets, including a new shower valve, at big box stores ensures easy accessibility, making the transition even more appealing. Say goodbye to the hassle of juggling cold and hot water with separate handles – a single-handle faucet provides a seamless and efficient way to enjoy a soothing shower or effortlessly fill your sink with the perfect temperature water.

How To Convert Two-Handle Faucet to Single Handle

If you’re dealing with a traditional two-handle faucet and want to enjoy the benefits of a single-handle faucet, you’re in luck. Converting a two-handle faucet to a single-handle design is a feasible DIY project that can make a world of difference in your daily routine. The process involves a few steps, such as turning off the water supply, disconnecting the existing faucet, and installing the new single-handle faucet. With the right tools and a little patience, you’ll have a sleek and modern faucet that’s easier to use and maintain.

Tools and Materials You’ll Need:

  1. Adjustable wrench
  2. Screwdriver
  3. Plumber’s tape
  4. New single-handle faucet
  5. Flexible supply lines (if not included with the new faucet)
  6. Basin wrench (optional, but helpful)
  • Step 1: Gather Your Supplies and Turn Off the Water Supply

Before you begin, ensure you have all the necessary tools and materials on hand. Also, remember to turn off the water supply to the faucet you’re planning to replace. Locate the shut-off valves beneath the sink and turn them clockwise until they’re fully closed.

  • Step 2: Disconnect the Old Faucet

Remove any items stored under the sink to create ample workspace. Use an adjustable wrench to loosen and disconnect the water supply lines from the existing faucet. Place a bucket or towel underneath to catch any residual water. Next, remove the nuts that secure the faucet to the sink using your wrench.

  • Step 4: Prepare the Sink for the New Faucet

If your new single-handle faucet requires a single-hole installation, you’re all set. However, if your old two-handle faucet is left behind with multiple holes, you’ll need to cover the extra holes using a deck plate or escutcheon. Place the deck plate over the holes and secure it in place using the provided hardware.


  • Step 6: Connect the Supply Lines

Attach the flexible supply lines to the faucet’s hot and cold water inlets. Use the plumber’s tape on the threaded connections to ensure a watertight seal. Tighten the connections using an adjustable wrench, being careful not to overtighten.

  • Step 3: Remove the Old Faucet

Once the nuts are removed, carefully lift the old faucet off the sink. You might need to wiggle it gently to detach it from any remaining sealant. Clean the sink surface to prepare it for the new faucet installation.


  • Step 5: Install the New Single-Handle Faucet

Follow the manufacturer’s instructions to install the new faucet. Typically, this involves placing a rubber gasket or seal onto the faucet base and threading the supply lines through the designated hole. Position the faucet on the sink and secure it with the provided nuts or mounting hardware. Use a basin wrench if necessary to access hard-to-reach areas.

  • Step 7: Turn On the Water Supply and Test

Once the new faucet is securely in place, turn on the water supply by reopening the shut-off valves beneath the sink. Check for any leaks around the connections and at the base of the faucet. If you notice any leaks, tighten the connections slightly until they’re snug.

You’ve successfully converted your two-handle faucet into a stylish and functional single-handle faucet. Enjoy the improved convenience and aesthetics that your new faucet brings to your bathroom or kitchen. Remember, if you’re unsure about any step of the process, it’s always a good idea to consult a professional plumber for guidance.

How to Replace a Kitchen Faucet with a Single Handle

Transitioning from a two-handle to a single-handle kitchen faucet involves similar steps, but you’ll need to cover extra holes left by the old faucet. A deck plate or escutcheon can help conceal these holes when installing a single-handle faucet that requires only one hole. Carefully follow the instructions provided with your new faucet, ensuring a secure and watertight installation.

How to Fix a Leaky Faucet

Even with the transition to single-handle faucets, occasional issues like leaks might arise. If you’re faced with a leaky single-handle faucet, addressing it promptly can save water and prevent further damage. Start by turning off the water supply, then disassemble the faucet handle to access the cartridge. Inspect the cartridge for any damage or wear, and replace it if necessary. Reassemble the faucet, turn on the water supply, and check for leaks. Remember that if you’re unsure about fixing the issue yourself, consulting a professional plumber is always a wise option.

Converting to single-handle faucets is a practical upgrade that enhances the functionality and appearance of your kitchen or bathroom. Whether you’re replacing an old two-handle faucet or simply giving your space a fresh look, the process is manageable for DIY enthusiasts. By following the outlined steps and considering the benefits of the switch, you can enjoy the convenience and style that single-handle faucets bring. Remember, a well-maintained faucet not only improves your daily routine but also contributes to a more efficient and sustainable home.

When You Should Call a Plumber

Knowing when to call a plumber can save you from potential headaches and costly repairs down the line. While some minor plumbing issues can be tackled on your own, certain situations warrant the expertise of a professional plumber. If you’re facing a sudden drop in water pressure, persistent leaks, burst pipes, sewage backups, or a lack of hot water, it’s time to pick up the phone. Additionally, strange odors, unusual noises, or slow drains might indicate underlying issues that a plumber can diagnose and address effectively. Remember, a prompt call to a plumber can prevent minor inconveniences from escalating into major plumbing disasters. So, don’t hesitate to reach out to a skilled plumber when you encounter these signs – their expertise ensures your plumbing remains in tip-top condition.
