How to Convert Two Handle Kitchen Faucet to Single Handle


It is quite easy to convert a double-handle kitchen faucet into a single-handle. But you’ll need to replace it with a one-handle faucet consisting of a wide base to cover the unused holes.

Both one-handle and 2-handle kitchen faucet have their advantages. Based on the benefits you are looking for, you may find yourself converting the kitchen faucet.

The following procedure of converting a double handle faucet to a single handle replacement entails two main parts. The removal of the existing two-handled faucet and the installation of the single-handled faucet.

How to Convert Two Handle Kitchen Faucet to Single Handle

7 Steps to Convert Two Handle Kitchen Faucet to Single Handle

Step 1: Collect the Needed Materials

You will need some tools and items to convert two faucets into one. The process entails disconnecting the piping system and some joints and reconnecting them. You cannot do this with your bare hands. First, look for the following items;

  • An adjustable wrench
  • Pliers
  • Old towels
  • A basin or bowl
  • Pillow
  • Basin wrench
  • Flashlight
  • Teflon tape
  • Safety glasses
  • Penetrating oil
  • An apron
  • Rubber gloves
  • Pipe or tube cutter

Put on your protective gear after acquiring what you require to replace the double faucet with a single one.

First, put on an apron to prevent your clothes from any dirt and spillage during the process. Then wear protective goggles and gloves.

Step 2: Clear the Area Under Your Kitchen Sink

Clear the Area Under Your Kitchen Sink

First, put on your protective gear after acquiring what you require to replace the double faucet with a single one.

First, put on an apron to prevent your clothes from any dirt and spillage during the process. Then wear protective goggles and gloves.

When you finish wearing safety gear, clear everything below the sink. If there’s a cabinet below your kitchen sink, remove all items until empty.

If you find an electrical outlet beneath your kitchen sink, switch it off for safety purposes.

Step 3: Switch Off the Hot and Cold Water Valves and Disengage Them

Switch Off the Hot and Cold Water Valves and Disengage Them

After removing everything from under the sink, you can now switch off the hot water and cold water supply valves. Turn the valves clockwise until wholly turned off.

Some sinks don’t have hot and cold valves installed beneath them. If yours is like that, switch off your main water supply.

With time, the valves may stick firmly, making it difficult to turn. In such a case, use pliers.

If you don’t have one, place a rag around the valve, then turn. The rag will help improve your grip, easing the turning.

After switching the valves off, disconnect the pipes supplied to them. The line to each valve connects through a threaded nut.

Use an adjustable wrench to loosen the nut by turning it anticlockwise. Water may spill out when you disconnect the cold and hot water supply lines. It will help if you put a basin or bowl beneath the lines before disconnection.

Corroded nuts may be stubborn to remove. Apply some penetrating oil to loosen them up.

Step 4: Search for the Two Handle Kitchen Faucet Connections and Remove Them

A double-handled faucet is usually connected to the hot and cold valves directly. Start by removing the mounting nut that secures the tap.

If it has a diverter with a line connecting the spout and the sprayer, you will have to disconnect the sprayer hose first.

Step 5: Detach All the Supply Lines Below Your Kitchen Sink and Remove the Double Handle Faucet

Now that you’ve detached the double-handled faucet connections, you need to disconnect all the supply lines beneath the sink. If the space below your sink is dark, light a flashlight for better visibility.

Also, a basin wrench will come in handy if you find it challenging to work on the connections beneath the sink due to limited space.

If you don’t need to use this two-handle faucet in the future, you may save yourself from all the hustle by cutting it using a pipe or tube cutter.

After disconnecting supply line connections below the sink, you need to remove the mounting hardware and the faucet.

You will find the securing nuts on the faucet’s mounting body. Please remove them and take out the tap. If some glue such as the caulk seal nuts reinforces the nuts, break it by applying pressure.

When you’ve disconnected and put the old faucet aside, clean the entire area before installing your preferred single-handled faucet.

Step 6: Assemble the Single-Handled Faucet

Assemble the Single-Handled Faucet

Before installing your one-handle faucet, check the number of holes the removed double-faucet used. Usually, you will find three or four holes.

One spot holds the faucet. The other two holes are for the cold and hot handles. If there’s a fourth hole, it’s for the sprayer or soap dispenser.

Though single-handled faucets come in different designs, they all come with spout and handles as one unit. That means you will need one hole to fix it.

You will need to cover the other holes using a base plate. Mostly, one-handled faucets get sold with the base plate. If not, you can buy one separately from the hardware next door.

In this stage of converting to single-handle faucets, you could be dealing with three or four sinkholes. That’s why it’s essential to be careful with the single-handle faucet to replace. In this procedure, we shall describe how to install a one-handled center set faucet.

The cold and hot water supply lines usually get designed within the faucet. But it may differ based on the faucet’s style.

The single-handled faucet set at the center also has a diverter used to connect the side sprayer.

Your single-handled faucet will come with instructions from the manufacturer on how to install it. Please read carefully and understand them.

We shall use a faucet that requires you to put the faucet gasket over the spout base in this procedure. After doing so, put the spout base to fit on the supply lines and the single-handled faucet’s body.

Step 7: Cover the Unused Faucet Holes

You only require one hole for the single-handle faucet. Cover the rest using a faucet hole cover. Sometimes the plate may contain a gasket. Utilize the gasket to seal the escutcheon plate (faucet hole cover) and the countertop gap.

Start by setting the gasket on the cover plate’s bottom side. Then put the hole cover on the supply tubes and the faucet’s shank.

Next, place the tap together with the hole cover plate on the sink’s mounting surface. The hole plate will cover all the unused holes.

5 Reasons for Converting a Double Handle Faucet to a Single Handle Faucet

1. User-friendly

Single-handled faucets are easy to operate. They turn quickly, making them ideal for kids or people with weakening hand conditions like arthritis.

You can even use your wrists and elbows to turn on a single-handled faucet. It makes it easier when your hands are dirty. You don’t have to soil the tap to use it!

2. Simple and Easy Installation

Unlike a double-handled faucet, the process of installing a single-handled one is easy. You don’t have to employ an expert to do it for you, saving your hard-earned dollars.

It will also not take much of your time.

3. Aesthetic Appeal

Most modern single-handle faucets come with fancy designs that appeal to the eyes. They also improve the look of the sink and the entire room.

4. Creates a Statement

Some other one-handled faucets help create a particular statement in the room. For example, if you are a fan of ancient antiques and designs, you can install a single-handle faucet that portrays the same. The market floods with them.

You can also choose a single-handled faucet made with a specific material like copper or gold to upgrade your room’s status, giving a luxurious statement.

5. Occupy Less Space

Unlike a double-handled faucet, a single-handled tap does not occupy much space. You can therefore install it in a small sink.

But you don’t just reverse the two-handle faucet to a single-handle faucet. You need to consider the following factors if you are to carry out the replacement procedure.

Things to Keep in Mind When Converting Double Handle to Single Handle

When you decide to change a two-handle faucet to a one-handle tap, you need to be entirely sure that it’s what you want and for the best.

Consider the use of the faucet. Will it be busy or not? Double-handled faucets are ideal for busy kitchens or bathrooms. The water flow is more and faster, causing convenience.

Single-handed faucets are ideal for small sinks without much activity. They are also best to use if you have invalids, the elderly, and kids in the house.

You can also control the flow and temperature of hot water with a double-handled faucet. You can hardly put on hot water accidentally.

Also, in case one valve has a problem, you can still access water from the other valve, unlike with a single-handled faucet.

Single-handed faucets come at various costs. You should consider whether you have the budget to buy the kind of one-handled faucet you want.

If the tap becomes more user-friendly and increases its functionality and other benefits when you replace a double handle faucet with a single handle, it’s worth it.

In the above guide, we have discussed how to reverse a two-handle faucet to a single-handle faucet in the presence of three or four sinkholes.

What if the sinkholes are two? How do we go about it? Here is a comprehensive answer to this critical question.

How to Install a Single-Handle Faucet in a 2-Hole Sink?

How to Install a Single-Handle Faucet in a 2-Hole Sink

A double-hole faucet to single-hole faucet installation is also not complicated. You only need to apply the following steps;

Step 1: Assemble the Required Tools

Like any other procedure, you need to collect any material necessary for the process. Ensure you have;

  • Pliers
  • An adjustable wrench
  • A sealant or suitable metal cover
  • Tape measure
  • Metal cutter

Step 2: Measure the Free Hole

You will use one sinkhole to install the single-handled faucet. The other one will be free and useless. It would be best if you got rid of it.

Start by taking the hole’s measurement using a tape measure or any other reliable measuring tool.

Step 3: Cut the Metal to Match the Gotten Measurements

After taking the hole’s dimensions, take a piece of metal and mark them out. Then use a reliable metal cutter to cut along the markings.

Step 4: Fix the Cutout Metal into the Free Hole

Take some metal sealant and apply it to the cut-out metal. Then fix it to the idle hole and leave it for some time to dry.

Step 5: Install the Single Handle Faucet

Using the other hole, install the single-handled faucet as directed in the manufacturer’s instruction manual. Attach all the parts and connections as required.

Step 6: Test if Working Properly

After installing the faucet with a single handle:

  • Test whether it’s working as expected.
  • Increase the faucet’s water flow capacity gradually to investigate any issues.
  • Check the behavior of the sealed hole when the tap is in operation.

In case of any leakage, tighten the screws or add the sealant until it stops. In doing so, the double hole faucet to single hole faucet installation will be complete.

Final Thoughts

Converting double handle faucets into single handle ones is not a new practice. As described above, you may get prompted to do so based on the services and benefits they are looking for.

Also, the procedure may differ slightly because kitchen faucets are different. It’s, therefore, crucial to understand the kind of kitchen fixtures you are dealing with before you begin the conversion process.

Also, remember to consider the factors discussed above when converting your kitchen’s two-handle faucet to a single one.
