Preparing for the Installation

Before you even think about touching your old sink, careful preparation is crucial. This phase involves gathering the right tools, disconnecting the old sink, and ensuring the countertop opening is appropriately sized for your new square kitchen sink.

Tools and Materials You’ll Need:

• New square kitchen sink
• Basin wrench
• Adjustable wrench
• Plumber’s putty
• Silicone caulk
• Pencil
• Measuring tape
• Utility knife
• Bucket
• Safety glasses
• Gloves
• Towels or rags
• Possibly a jigsaw (if the opening needs adjustment)

Removing the Old Sink:

1. Shut off the water supply: Locate the shut-off valves under your sink and turn them clockwise to stop the water flow. Place a bucket underneath to catch any residual water.
2. Disconnect the plumbing: Use a basin wrench to loosen and disconnect the water supply lines from the faucet. Then, disconnect the drainpipe. Be prepared for some water to spill.
3. Remove the old sink: Carefully detach the clips or fasteners holding the old sink in place. Use a utility knife to score any caulk that may be sealing the sink to the countertop. Lift the old sink out of the opening.
4. Clean the countertop: Remove any old caulk, debris, or grime from the countertop surface.

Installing Your New Square Kitchen Sink

Now comes the exciting part – installing your new sink! This involves fitting the faucet, applying sealant, securing the sink, and connecting the plumbing.

Step-by-Step Installation:

1. Install the faucet and drain assembly: Before placing the sink in the countertop, install the faucet, sprayer (if applicable), and drain assembly according to the manufacturer’s instructions; This is often easier to do with the sink upside down.
2. Apply Plumber’s Putty: Roll out a rope of plumber’s putty and apply it around the underside of the drain flange where it will meet the sink. Press the drain flange into place and tighten the nut from underneath. Remove any excess putty.
3. Apply Silicone Caulk: Apply a bead of silicone caulk around the rim of the countertop opening. This will create a watertight seal.
4. Position and Secure the Sink: Carefully lower the square kitchen sink into the countertop opening, aligning it properly. Press down firmly to ensure the caulk makes good contact. Install the clips or fasteners that came with your sink to secure it in place. Tighten them evenly to avoid warping or cracking the sink.
5. Connect the Plumbing: Reconnect the water supply lines to the faucet, ensuring they are securely tightened. Connect the drainpipe to the drain assembly, making sure all connections are watertight.
6. Test for Leaks: Turn the water supply back on slowly and carefully. Check all connections for leaks. If you find any leaks, tighten the connections until they are sealed.

Finishing Touches

Once the sink is installed and leak-free, it’s time for the finishing touches.

Cleaning and Sealing:

• Wipe away any excess caulk or plumber’s putty.
• Clean the sink and surrounding area with a mild detergent.
• Inspect all connections one last time.
