Do it yourself

Install or replace a kitchen sink on a laminate countertop

Drop-in sinks, whether with a single, double or triple bowl, are all equally quick to install because only one cut needs to be made. Here, we will show you how to install a single-bowl sink.


Before you start, turn off the water supply with the shut-off valves.
Wear safety glasses when working under the sink and protective gloves when using the jigsaw.

Prepare the countertop for cutting

  • 1.1 - First, lay the sink template on the countertop and draw a line around it. The template is usually provided in the sink’s box. Make sure that the outline is parallel with the counter's edge.
  • 1.2 - Using a drill, make a hole at one of the corners of the outline, staying ½ in inside the cutting line.
  • 1.3 - Drill a larger hole so you can insert the 5/8 in jigsaw blade.
  • 1.4 - Stick masking tape around the cutting line to prevent splinters.

Cut the counter

  • 2.1 - Use blocks to support the sink cut-out.
  • 2.2 - For a clean cut, use a jigsaw blade specially designed for laminates.
  • 2.3 - Lower the sink into the opening to check that it fits well. Cut out more counter if needed.

Place the strainer

  • 3.1 - Take the sink out.
  • 3.2 - Apply a bead of plumber's putty around the sink drain hole. Place the strainer in the hole and press down firmly.
  • 3.3 - Under the sink, slip a rubber gasket over the neck of the strainer and tighten the lock nut to secure the strainer to the sink.

Install the faucet

  • 4.1 - While you have enough space to do it, install your kitchen faucet.
  • 4.2 - Make sure the base of the faucet is parallel with the back of the sink.

Place the sink in the opening

  • 5.1 - Apply plumber's putty (or bathroom and kitchen caulk) around the bottom edge of the sink.
  • 5.2 - Lower the sink into the opening and press it down firmly to fasten it securely to the countertop.
  • 5.3 - From under the sink, tighten the mounting screws and wipe off any excess putty.
  • 5.4 - Let it dry.

Connect and test

  • 6.1 - Use the waste pipe and a P-trap to fit the strainer body to the wall pipe.
  • 6.2 - Fit washers onto the ends of the connections and strengthen with slip nuts, tightened with a pipe wrench.
  • 6.3 - Finish by opening the water and checking for leaks.
