How Install Bathroom Faucet? The Do It Yourself Method

Though most people call on the services of a professional plumber to install or replace their bathroom faucet, this is a fun and simple project that you can complete yourself with just a few simple tools. In less than an hour, you’ll be enjoying your accomplishments with a brand-new faucet. So, how to install bathroom faucet?

What Type of Faucet Should You Be Shopping For?

As a rule, you should remove your old faucet and take it to a hardware store for comparison. If you’re installing a new faucet, don’t be overwhelmed by the many options on the market. There are three general categories they fall into:

✔️ Single-hole

This type of faucet fits in the single-hole sink design and is the perfect option for smaller spaces. If your counter has only one hole, then this is the best option for you.

✔️ Centerset

Centerset faucets are the most common type. They typically fit in a four-inch spread with a two-handle design for both hot and cold water. If you have three holes in your countertop with a four-inch spread, this is a great choice.

✔️ Widespread

​Widespread faucets also utilize a three-hole drill space; however, their spread is typically wider and measures eight-inches apart. If you have three holes in your counter top that are pre-drilled with an eight-inch spread, this option is best

If you have your heart set on a faucet that doesn’t conform to your counter top, you still have options. For example, a three-hole design can accommodate a single-hole style faucet by utilizing a deck plate. Moreover, when purchasing a new counter top, you can customize the drilling of the holes to any style you choose.

Here Are the Tools You’ll Want to Have Around Before You Get Started:

✔️ ​Basin wrench (in case you’re working in hard to reach places)

✔️ Adjustable pliers or adjustable wrench

✔️ Mineral turpentine

✔️ Bucket to catch water

✔️ Sealant or plumber’s putty

Turning Off the Water Supply

​Before removing the old faucet, it’s important that you turn off the water supply from underneath the sink. However, if there are no water supply valves under your sink, you’ll want to shut off the water main to your home before getting started. After you have shut off the water supply, turn the faucet on to release any residual water pressure from the pipes.

Disconnecting the Supply Lines from the Old Faucet

Now, unhook the water supply lines from the old faucet. If they are too tight or you can’t reach them, your adjustable wrench or basin wrench will come in handy here.

Remove the Nuts from Under the Faucet

Next, using your adjustable wrench or basin wrench, remove any hardware such as nuts and washers from under the old faucet. Then, gently lift the old faucet from the top of the sink to remove it. If the old faucet is stuck in place, gentle rocking should loosen it from the sink. If the old faucet still does not come lose, check to see if you’ve missed any hardware from underneath that still needs to be removed.

Removing the Old Drain

Now it’s time for you to remove the old drain. You’ll be removing the P-trap which is the curved piece of pipe under the sink drain.

a) Grab your bucket and place it under the P-trap to catch any residual water that may leak.

b) Unscrew the nuts on the P-trap and remove.

c) ​Next, unscrew and remove the drain flange by loosening it at the collar connected to the underside of the sink drain.

Installing Your New Faucet

Before installing your new faucet, it’s a good idea to clean old silicon sealant and dirt from around the drain holes. A mineral turpentine with a rag or sponge works well to remove any residue left behind.

Manufacturer’s Instructions and Handle Assembly

​a) ​Always follow the included manufacturer’s instructions for any specific assembly requirements for your new faucet. Some faucets require simple assembly of the handles before installation and should include the necessary Allen wrenches for the job.

b) ​Now, once the faucet handles are fully assembled, place the faucet through the mounting holes on your sink counter.

c) ​Then, tighten the mounting nuts under the faucet with your adjustable wrench or basin wrench.

Installing the New Drain

☑️ ​Unscrew the nut on the new drain pipe all the way down to expose the threads fully.

☑️ ​Then place the gasket onto the drain pipe over the nut. The gasket is the rubber ring that will seal the gap between the drain body and the bottom of the sink.

☑️ ​Next, place a small amount of plumber’s putty around the underside of the drain body flange. That’s the part that goes into the drain hole. This will ensure a good seal against the basin of the sink.

☑️ ​Now join the drain pipe and flange from the top and bottom of the sink and tighten the flange from the top by hand.

 ☑️ ​Finally, under the sink, tighten the nut and gasket with an adjustable wrench and wipe away any putty residue with mineral turpentine before it dries.

Installing the New Drain Lift Rod

The lift rod will close your new drain when you want to fill the sink with water. It is made up of a horizontal rod that will be inserted into the side of the drain and a strap and clip that will connect to the lift rod from the top.

☑️ ​Unscrew the pivot nut from the side of the drain and insert the horizontal rod with the ball end of the horizontal rod in the drain. Then, tighten the nut.

☑️ ​Next, slide the lift rod strap and clip onto the horizontal rod and insert the lift rod down through the faucet into the strap.

 ☑️ ​Finally, while pushing the horizontal rod down, tighten the lift rod to the strap screw.

Reconnecting the Water Supply Lines to Your New Sink

☑️ ​Now, connect and tighten the water supply lines to the underside of the faucet. If the underside of the faucet is difficult to reach, tighten the supply lines with your basin wrench.

☑️ ​Next, remove the faucet aerator by unscrewing it from the faucet head.

☑️​ Then, turn back on the water supply or water main and run the water on both hot and cold to flush the new system of any debris while checking above and below your installation for any leaks.

☑️ ​Finally, turn the water off and replace the faucet aerator.

You’re Done! Congratulations!
