Installing a kitchen sink can feel like a major task, but with the right tools and guidance, it's a manageable DIY project. Whether you're remodeling your kitchen or just replacing an old sink, learning how to install a kitchen sink is essential for a successful outcome. This guide covers everything from preparation to final plumbing connections.

Tools and Materials You’ll Need

Before beginning the installation, gather the following:

  • New kitchen sink

  • Faucet and strainer assembly

  • Plumber's putty or silicone caulk

  • Adjustable wrench

  • Pipe wrench

  • Basin wrench

  • Bucket and rags

  • PVC pipes and fittings

  • Teflon tape

  • Screwdriver and putty knife

1. Remove the Old Sink

Start by turning off the water supply. Disconnect the faucet lines and install kitchen sink plumbing carefully using a wrench. Place a bucket underneath to catch any water. Remove the mounting clips and cut through any sealant with a utility knife. Carefully lift out the old sink.

2. Prepare the Countertop Opening

Check if your new sink fits in the existing cutout. If not, you may need to enlarge the opening. Measure twice, cut once. Once you're sure of the fit, clean the countertop edges thoroughly.

3. Install the Faucet and Accessories

It’s easier to install the faucet, sprayer, and soap dispenser (if any) before placing the sink into the counter. Use a plumber's putty around the base of the faucet and tighten it from below using a basin wrench.

4. Apply Sealant and Set the Sink

Apply a bead of plumber's putty or silicone caulk around the edge of the sink cutout. Carefully lower the sink into place and press down to ensure a watertight seal. Wipe away any excess sealant.

5. Secure the Sink

Use the mounting clips that come with the sink to secure it from underneath. Tighten them evenly, working from corner to corner to avoid shifting the sink.

6. Connect the Plumbing

Once the sink is in place, it's time to connect the kitchen sink plumbing. Begin with the drain strainer, apply plumber’s putty to the underside, press it into the drain hole, and secure it with the locknut. Next, connect the P-trap and drainpipes using PVC fittings.

Make sure the drain lines align properly. For double-basin sinks, a T-fitting is used to join the two drains. Tighten all connections and use Teflon tape on threaded joints to prevent leaks.

7. Connect the Water Supply Lines

Reconnect the hot and cold water lines to the faucet using flexible supply lines. Tighten with a wrench, but avoid over-tightening to prevent damage.

Once connected, turn the water supply back on and check for leaks.

8. Test and Final Adjustments

Run water through the sink and check all connections. Look under the sink for any signs of dripping. If any leaks are found, turn off the water and tighten the affected joints.
