Step 1: Turn off the Water Supply

Before you begin, you'll need to turn off the water supply to your kitchen sink. Locate the shut-off valves underneath the sink and turn them clockwise to shut off the water. If you can't find the valves or they are not functioning correctly, you'll need to shut off the main water supply to your home.

Step 2: Remove the Old Sink

Next, you'll need to remove the old sink. Start by disconnecting the water supply lines and the drain pipe from the sink. You may need pliers or an adjustable wrench to do this. If the sink is attached with mounting clips, remove them with a screwdriver.

Once you've disconnected the sink, carefully lift it out of the countertop and set it aside.

Step 3: Prepare the Area

With the old sink removed, you'll need to clean and prepare the area for the new sink. Use a scraper or putty knife to remove any old caulk or plumber's putty from the countertop.

Next, position the new sink in the countertop cutout and mark its outline with a pencil. Remove the sink and apply a bead of silicone caulk around the edge of the cutout.

Step 4: Install the Faucet

Before installing the sink, you'll need to install the faucet. Begin by installing the mounting hardware according to the manufacturer's instructions. Then, feed the faucet lines through the holes in the sink and tighten the mounting nuts from underneath the sink.

Step 5: Mount the Sink

With the faucet installed, it's time to mount the sink. Carefully position the sink in the cutout, making sure it's level and centered. Install the mounting clips by sliding them under the sink and tightening the screws with a screwdriver.

Step 6: Connect the Plumbing

Finally, it's time to connect the plumbing. Begin by connecting the water supply lines to the faucet. Tighten the connections with pliers, being careful not to overtighten and damage the fittings.

Next, install the drain assembly according to the manufacturer's instructions. This may involve cutting and fitting the drain pipe, so make sure you have a pipe cutter or hacksaw on hand. Tighten the connections with pliers.

Step 7: Test the Sink

With the plumbing connected, it's time to test the sink for leaks. Turn the water supply back on and check for any leaks around the faucet and drain connections. If you find any leaks, tighten the connections as needed.


Installing a new kitchen sink may seem like a challenging project, but with the right tools and some basic knowledge, it can be a satisfying DIY accomplishment. By following these steps and taking your time, you'll have a new sink that not only looks great but functions perfectly.
