How To Replace Bathroom Sink Faucet

During my bathroom makeover, I decided to replace my bathroom sink faucet, along with my bathroom sink. Even with the best care, sink faucets wear out with time. Faucets are used daily and come in constant contact with water and moisture. Additionally, faucets are made up of numerous important parts such as – washers, gaskets, mounting hardware, etc. Over time with use the washers wear out, gaskets become loose and the mounting hardware can corrode. In my experience, a good quality faucet will serve you well for five to eight years.

As I choose to give my bathroom a complete makeover, I dismantled my sink faucets along with the sink and removed my sink countertop. Observing my sink faucets, I noticed slight corrosion in my mounting hardware. Some amount of corrosion is normal, given the constant exposure to water and moisture. But, given that I was installing a new sink, I choose to buy new faucets as well.

Bathroom sink faucets come in several types. Primarily they are categorized based on the number of faucet openings you’ll need on your sink countertop or in your sink itself. Based on your preference, you can choose any of the following options to replace your bathroom sink faucet –

Single Hole Faucet –

As you would’ve guessed, this faucet requires only one opening and is standard for single handle bathroom sink faucets.

Center – Spread Faucet –

If you have a sink with three holes, typically with a gap of four inches between them, this is the best choice for you. You’ll need an escutcheon plate to link the holes together.

Widespread Faucet –

For sinks having three holes, six or more inches apart, this faucet is your best bet. In widespread faucets, your handles and the faucet will be three individual pieces.

I chose to go forward with a center – spread faucet for which I drilled three faucet openings into my countertop. In case you are replacing just your faucets, it would be cost and time-effective to select the same type of faucet as your last one. However, you could replace a center-spread or widespread faucet with a single hole faucet and vice-versa. It takes some work as your countertop will need to be modified based on the number of additional faucet openings you will require.

Be mindful that if you have bought a sink which has a set number of faucet holes already, you will not be able to change it.

IMPORTANT TIP – Drilling into your sink to add faucet openings will crack or break the sink. Only drill into your countertop if need be. In-built faucet openings in sink cannot be modified.

You can still choose from a variety of options for your new bathroom sink faucet. Let’s say your new sink has three in-built faucet holes. You can still choose to opt for a single hole faucet. Utilizing only one of the openings and covering the rest with an escutcheon plate. Similarly, you can attach a center-spread faucet to your sink as well.

Depending on your faucet manufacturer, along with your bathroom sink faucet, you can also replace your bathroom sink plumbing. Many replacement kits provide you with new pipes along with the faucet apparatus. We recommend taking advantage of this opportunity and replacing your plumbing.

Remember, before beginning to replace your bathroom sink faucet, turn off the main water valves. Typically, the valves will be under your sink. Additionally, place a bucket beneath your sink to collect any spillage when you replace your plumbing. Once you have taken these preliminary steps, you are ready to replace your faucet.

Hence, do not rush to avoid future leaks or damage to your pipes.
