What You’ll Need

Before you start the installation process, you’ll need to gather the following materials:

  • Kitchen sink
  • Faucet
  • Drain kit
  • Adjustable wrench
  • Silicone sealant
  • Plumber’s putty
  • Hacksaw or pipe cutter
  • Tape measure
  • Plumber’s tape

Step 1: Prepare the Area

Before you begin, make sure to turn off the water supply to the sink. Then, remove any items from the cabinet underneath the sink and lay down a towel or bucket to catch any excess water that may be present in the pipes.


Don’t start the installation process without turning off the water supply.

Step 2: Install the Sink

Place the sink into position and use a tape measure to ensure that it is level. Once it is positioned correctly, use a silicone sealant to secure it in place.


Do use a level to ensure that the sink is installed properly.

Step 3: Install the Faucet

Follow the manufacturer’s instructions to install the faucet onto the sink. Use plumber’s putty to create a watertight seal around the base of the faucet.


Don’t over-tighten the faucet, as this could cause damage to the sink.

Step 4: Connect the Drains

Use a drain kit to properly connect the drains to the sink. Use plumber’s tape to ensure a tight seal at all connections.


Do check for any leaks once the drains are connected, and make any necessary adjustments.

Step 5: Test the Sink

Turn the water supply back on and run water into the sink to check for leaks. If everything is secure, your installation is complete!
