How To Install A Drop In Kitchen Sink

Installing a drop in kitchen sink is a relatively simple plumbing project that can be completed in a few hours. By following these step-by-step instructions, you can save yourself the cost of hiring a plumber.

Tools and Materials You'll Need:

Drop-in kitchen sink
Sink strainer
Plumber's putty
Caulk gun
Caulk
Adjustable wrench
Putty knife
Utility knife
Measuring tape
Level

Step-by-Step Instructions:

1. Prepare the Countertop

Start by measuring and marking the location of the sink on the countertop. Use a utility knife to cut out the hole for the sink, following the manufacturer's instructions. Be sure to wear safety glasses when using the utility knife.

2. Apply Plumber's Putty

Roll out a rope of plumber's putty and apply it to the underside of the sink's rim. The putty will help to create a watertight seal between the sink and the countertop.

3. Set the Sink in Place

Carefully lift the sink into place and set it in the hole in the countertop. Press down on the sink to ensure that the putty forms a good seal.

4. Install the Sink Strainer

Place the sink strainer in the drain hole and tighten the nuts to secure it in place.

5. Connect the Plumbing

Attach the water supply lines to the sink's faucets. Use an adjustable wrench to tighten the connections.

6. Caulk Around the Sink

Apply a bead of caulk around the edge of the sink where it meets the countertop. Use a caulk gun to apply the caulk evenly.

7. Level the Sink

Use a level to check that the sink is level from side to side and front to back. If the sink is not level, use shims to level it out.

8. Tighten the Sink Clips

Once the sink is level, tighten the sink clips to secure it in place.

9. Run the Water

Turn on the water supply and check for leaks. If there are any leaks, tighten the connections or apply more caulk.

Tips:

If you are replacing an existing sink, be sure to turn off the water supply and disconnect the plumbing before removing the old sink.
Use a level to ensure that the sink is level before tightening the sink clips.
Apply caulk around the edge of the sink to prevent water from seeping under the sink.
If you are not comfortable installing a sink yourself, you can hire a plumber to do it for you.
