What You Need


  • A new kitchen sink that fits both width, length and depth of the existing space
  • Plumber’s putty
  • Your brand new sink!

If you require wooden shim spacers to hold heavy sink:

  • Drill and bits
  • Screws
  • Wooden pieces of the correct size


  • Crescent wrench
  • Screwdrivers
  • A scraper of some kind for caulk and putty


Remove the old sink:

1. Turn off the water valves under the sink and disconnect lines from the wall valves.

Install new sink:

1. Some sinks (like the one installed here) does not use screw-in clips to hold it. Instead, you need to install spacers to hold the sink in the right place. Cut wood pieces, and screw them into the inner sides of the countertop.

2. Run a small amount of plumber’s putty around the perimeter of the sink before installing it. This will ensure it will be watertight.

3. Attach the new faucet to the new sink and connect the water lines to the sink before you put it into the counter top . If you’re unsure how to do this, Lowe’s has a helpful tutorial.

4. Reconnect the garbage disposal to the sink drain.

5. Lift the entire sink/faucet/garbage disposal assembly and place it into the opening of the counter top. (This photo was taken before the faucet was attached but you get the idea.)

6. Connect the water lines and drain lines under the counter as they were originally. Turn on the water valves and check for leaks.
