How to Remove a Bathroom Sink Faucet

What You'll Need
Adjustable wrench or basin wrench
Safety glasses
New faucet attachment
Plumbers tape
Plumbers putty
WD40 or penetrating oil

Removing your bathroom sink faucet is a relatively simple project. Simply follow a few guidelines and rules and you will have a brand new faucet attached in no time. Certain rules do apply depending on the type of faucet you have. If you have a one-piece faucet, it will be attached to your sink using 2 holding nuts. If you have separate faucets without a mixer, you will need to remove each faucet independently.

Step 1 - Preparation

Older sink faucets will have been stuck down using plumber putty and older pipes can be quite brittle. Make sure, before you start, that you have the correct equipment for removing your faucet. Your sink may also have mixer taps or a plunger built into the faucet for closing the plug hole. Ensure that you buy the correct replacement part before you begin this project.

Step 2 – Water Supply

The first thing you will need to do is switch off the water supply that goes to your sink or bathroom. Locate your water stop valve and turn off the water. Depending on your home, you may have a valve for hot and cold water and some homes have independent shut off valves on each feed pipe under the sink. Make sure all the water is turned off.

Step 3 – Prepare the Area

Lay out some dry rags, cloths or towels around the bottom of the sink area. If you have a vanity unit below your sink place dry cloths inside to prevent any escaping water from damaging a wooden cabinet floor.

Step 4 – Loosening the Nuts

Using the adjustable wrench, loosen the compression nuts that attach to each separate faucet’s supply pipes. If they are particularly difficult to remove, avoid breakage by using a little WD40 or penetrating oil on them and letting them loosen by themselves. Then, when the oil has soaked in you should not have any trouble removing the nuts.

Step 5 – Faucet Pipes

Locate the holding nuts that attach each faucet pipe to the sink. These will be the 2 nuts that are directly attached against the underside of the sink unit. Remove those nuts. Now your faucet should slide easily out of the sink holes. If it does not directly slide out you may need to wiggle it to remove any of the older putty that is sticking it down onto the sink top.

Step 6 - Removal

If your sink is a one piece sink you may have trouble accessing the plumbing from underneath, so be careful not to damage the surrounding molded area. Thoroughly clean around the tops and undersides of the sink holes and offer them a clean base for the new faucet to sit. If your water supply is a little limy you can use a Brillo pad or pan scrubber for particularly stubborn marks. Make sure the top and underside of the sink is totally clean and dry before installing your new fitting.
