Removing a bathroom sink is not a difficult process. With the proper tools and these easy steps you will have that sink out in no time.

Step 1 - Shut Off Water

The first step is to shut off all water sources to your sink. Most homes will have shut-off valves located directly underneath or near your sink vanity. Turn valve to the right to shut off water flow. In older homes there may not be a valve, so you need to shut off the water at the main valve or well pressure tank.

Step 2 - Identify Faucet Type

Determine if your faucet is a single lever or a dual type faucet. A single lever faucet is one that has a roller type ball for water control. A dual faucet control has individual water controls to access hot or cold water.

If your faucet is a single lever, you will need to remove the nuts that hold the single copper or PEX tube (supply riser) that extends down from the sink to the faucet valve. Then, remove the large nuts that hold the supply riser to the wall mounted valves.

For a dual faucet system, the process is the same but you will have 2 individual shut off valves and 2 supply risers to remove.

Use the Open-End Wrench or adjustable Pliers to remove the nuts connected to the water valve and the sink faucets. Place a pail underneath the supply risers as you disconnect, to catch any residual water in the tube.

Step 3 - Remove Waste Line

A sink's waste line is the large tube that is connected to the middle of the sink, then forms a "u" and exits through the wall. You will need to put a pail under this line upon removal because there will be water pooled in the base of the "u." Use the adjustable pliers to turn the nuts counterclockwise to disconnect.

Step 4 - Identify Retaining Clips

Now that the water sources are removed, it's time to tackle the sink itself. With the aid of your flashlight you will need to literally lay in the cabinet under the sink to find the retaining clips that keep the sink secure in the cut out of the cabinet top. These clips, or whatever is being used to secure the sink to the counter top, will all need to be removed.

They are designed to easily snap out of position with a firm grip or pull with a pair of pliers. If there are no clips, that is just one less step you have to apply!

Step 5 - Loosen Caulk

Use a putty knife to cut the caulk seal from around the top and bottom of the sink. This is the glue that keeps the sink sealed and solidly positioned on the counter top, so remove as much caulk as you can.

Step 6 - Remove Sink

Lift the sink straight up and off the countertop. Place gently down on a prepared surface, since it can leave scratches if handled too roughly.
