    a) Site the opening appropriately

    Occasionally, sink manufacturers give a template. Appropriately, place the template so that it is in the center of the sink cabinet. Again, it should be at least 1 1/2 inches back right from the front edge of the countertop. In case your countertop is longer than 24 inches, put it considerably back, but not longer than 4 inches. Preferably, use the masking tape to tape the template then draw it with the pencil.

    Ordinarily, a sink measuring up to 22 inches deep will suitably fit in a standard 24-inch-deep cabinet. Actually, this is the case if you do not have a backsplash. Otherwise, your countertop will just accommodate a sink up to 20 1/2 inches deep. Undoubtedly, your options will increase in case you are replacing your countertop and cabinetry too.

    Afterwards, remove the template and appropriately pierce a hole in each corner. Put the plate (saber-saw) in one of the holes and begin cutting along the interior of the line. Most importantly, be careful avoid the cutout snapping off and stumbling while you complete the cuts. Accordingly, screw a piece of wood from front to back on the tip of the cutout. As a matter of choice, it should be long enough to traverse the opening and some inches. Next, simply raise the cutout from your template.

    c) Install the faucet and the sink strainers

    Installing the faucet

    ✔️ First, thread the sprayer through the body of the faucet.

    ✔️ Put the rubber gasket between the sink top and the bottom of the faucet to build a watertight seal.

    ✔️ Fit the mounting nut.

    ✔️ Attach the sprayer to the body of the faucet (In case you are installing a pullout sprayer).

    ✔️ Attach the counterweight

    ✔️ Hook up the cold and hot supply lines to the water equipment shutoff plugs beneath the sink

    Preferably, you should fix the faucet and the sink strainers when you can access the sink. Therefore, avoid fitting the pieces in from beneath after installing the sink. Subsequently, use a plumber's putty or a bead of silicone caulk throughout the perimeter of the base sink's lip. Indeed, this is important in creating a watertight coat between the countertop and the sink.

    d) Place the assemblage in the cutout

    Cautiously, flip the sink over and introduce into the opening, ensuring that the putty or the caulk is stable. Next, you can fix the kitchen sink. In case your sink is heavy, you may seek assistance lifting and fixing it. More so, consider putting some scraps of wood close to the edge of the opening to hold the sink. As a reminder, be careful not to hurt your fingers as you lower it into place.

    e) Tighten the base of the sink

    Quite a number of sinks are stretched down firmly against the countertop using distinctive mounting clips. Normally, this hook onto the lip under the sink and are bound with a nut driver or screwdriver. Carefully, follow the directions of your manufacturer for spacing the clips. Fasten the mounting clips may make the putty or caulk to squeeze out from beneath the sink lip. With that in mind, you will want to eliminate the excess using a clean and soft rag.

    f) Connect the P-trap

    Ultimately, to finish the installation of the kitchen sink, you need to connect the P-trap. Carefully, link the faucet lines to the cold and hot supply lines. Preferably, make use of elastic supply tubes and attach the waste line to the strainers. After this, you will need to:

    ✔️ Turn the water on at the valves (shut-off valves)

    ✔️ Separate the aerator from your faucet

    ✔️ To flush the system, turn on the water from your faucet

    ✔️ Finally, reinstall the aerator after running the water for about a minute


    Ideally, you can install a kitchen sink yourself. However, getting a professional to do it is recommended. This will make sure that the sink is perfectly supported and sealed to avoid leaks. Additionally, it will stop from possibly collapsing beneath the weight hefty load of dishes. While you might not use all the requirements for installing your sink, it is good to always avail them.
