How to Remove a Kitchen Sink

What You'll Need
Cordless screw gun
Adjustable wrench
Rubber mallet or hammer
Adjustable multi-groove pliers

There are many types of kitchen sinks available in the market, but the most popular among them is made of stainless steel. Sinks are easy-to-install, easy-to-clean, and show less wear and tear than their counterparts. Still, with age, they occasionally need to be replaced. With a few tools in hand, it is possible to remove sinks with the least fuss and bother. If there is a cabinet underneath, you may want to remove its doors so you can make more room for ease of movement.

Step 1 – Remove the Cabinet Door

If there is a cabinet under the sink, remove the door screws using a cordless screw gun with a Phillips head bit. Keep the screws on the same hinge so that you do not misplace them, using a piece of tape to hold them together. If the screws get mixed up, in some cases, the doors will not give the same swing as before. 

Step 2 – Disconnect Water Lines

Disconnecting the waste and water supply line to the sink is the next step. Shut off the hot-cold water valves found under the sink. In case these valves cannot be located, shut off the main valve which supplies water to the house. Turn on both the taps to allow the remaining water to escape and to verify that the water connection has been turned off properly. When all the water has been emptied, shut the tap off. Before disconnecting the water or drain lines, keep a bucket under the sink. Using an adjustable wrench, disconnect the water supply lines from the bottom of the tap. You can loosen the nut with the wrench and finish the task with your fingers. 

Step 3 – Disconnect the Drain Line

Reposition the bucket under the drain line before attempting to disconnect it. Loosen the large plastic nut from the drain pipe with your fingers, or if necessary, with adjustable multi-grove pliers, to remove it. Loosen the plastic nut from the other side of the P-trap (This U-shaped pipe usually contains the wastewater from the sink. This water works as a barrier and keeps the sewer gases from wafting up the sink). Using pliers remove the P-trap and empty the water into the bucket. Loosen the screws on the hose clamp with a screwdriver, and remove the clamp. 

Step 4 – Dislodge the Sink

Remove the screws holding the sink in place, using the screwdriver. Place a wide putty knife between the sink and the countertop. Using a rubber mallet or hammer, tap the putty knife, until it slides under the sink; then, run it along the edges. This process is done to break the seal without damaging either the sink or the surrounding areas. 

Step 5 – Remove the Sink

Remove the basket strainer from the sink. Then, remove the sink from the countertop opening and place it on its side, carefully. 

Step 6 – Remove the Tap

Using pliers, remove the 2 plastic nuts which hold the tap in place from underneath the sink. Finally, remove the taps.
