Converting A Two Handle Bathroom Sink Faucet to a Single Handle Faucet

Last Updated: January, 2022 | By JULIAN GILL

Interested in converting a two handle bathroom sink faucet to a single handle faucet instead?  This is a great, popular upgrade that is very popular for a lot of great reasons.  Here’s what you need to know in order to convert your faucet!

How to convert your two handle faucet to a single handle faucet

One of the cool things about changing your faucet from a two handle faucet to a single handle faucet is that it’s all about the looks.  The actual switch is going to be very easy.  Take a look for yourself!

  1. Prepare your space: This means having all of the right tools (your new faucet, a wrench, a screwdriver, pliers, O-rings, a bowl for catching water, a flashlight, teflon tape, etc.  Also, turn off your water at this stage.
  2. Disconnect water supply lines: Turn each nut counter-clockwise and liaise it to disconnect the water lines.
  3. Remove the old faucet: Carefully remove the old faucet, including the supply lines, the connections, the mounting hardware, and the faucet itself.  Take your time with this step to make sure you don’t damage your water supply lines or your vanity/countertop.
  4. Install an escutcheon plate to cover the holes: This is the secret part!  Since your single handle faucet only needs one hole, you will want to cover the other holes with a plate. 
  5. Align everything to the center hole: When you are installing the faucet, make sure it is going into the center hole of your vanity/countertop.
  6. Install the drain and faucet head: Following the instructions, install the drain and faucet head in the center hole.
  7. Reconnect the water lines: Connect the water lines and then tighten the connections to prevent leaks.
  8. Test and check for leaks: Make sure your cold and hot water are coming out at the right place on your single handle faucet (according to the markings), and that there are no water leaks.

Why should I convert a two handle to a single handle faucet?

The main thing, here, is that converting is a personal choice.  If you love your traditional two handle bathroom sink, there’s no need to change!  However, single handle faucets have some great pros to consider, too.  For example:

  • They are accessibility friendly: You can turn on single handle faucets with your elbow if you have issues with your hands
  • You can get the temperature just right: With more control over the temperature itself, you’ll be able to get the temperature just right, even if it’s different every time.

They are great space savers: If you have limited space, this will make more space on either side!  It’s a single hole rather than three holes and taps, after all.

What should I keep in mind when converting a two handle to a single handle faucet?

While a single handle faucet is the best choice for most people, not everyone is going to love them.  Some may find them dangerous for little kids who turn them too far and scald themselves.  These are best used with parent supervision!
