Factors to Consider while Selecting a Kitchen Sink Size

Kitchen Size

Always consider your kitchen size while selecting the size of your sink. For a small kitchen, where space is at a premium, installing a small sink means more counter area.

Even if space is not an issue, make sure that the sink is proportionate to the overall kitchen layout.

Base Cabinet Size

To determine your maximum sink size, you’ll need to consider the size of the base cabinet. Standard kitchen cabinets are 36″ to 42″ high, 25 1/4″ to 26″ wide, and 24″ deep.

A large-sized kitchen sink on a small base cabinet will reduce the overall cabinet space.

Surrounding Area

Just like the kitchen size, consider the size of surrounding elements too. Check out the nearby fixtures—stove, counter, cabinet detailing, accessories, and the like.

Measure these fixtures to find out if your kitchen sink will look proportionate.

How to Install a Kitchen Sink

It is possible to replace your old kitchen sink and install a new one without destroying your countertop. By following the steps mentioned below, you can learn how to install a kitchen sink like a pro.

Old Kitchen Sink Removal

Step 1

Turn off the water supply lines (hot & cold). If you cannot turn off the water supply of your sink, turn off the main water supply of your home.

Step 2

Disconnect the water supply lines attached to the faucet. Make sure you put a bucket beneath the water supply lines to prevent the water from spilling.

Step 3

Turn off and unplug the garbage disposal (if you have one). Remove it as per the instructions provided by the manufacturer.

Step 4

For Undermount Kitchen Sinks

Remove the caulking/silicone around the sink. Do not remove the supports of the sink until the seal of the sink is broken.

Once the seal is removed, carefully remove the supports to remove your undermount kitchen sink.

For Topmount Kitchen Sinks

Remove the flanges around the rim of the topmount kitchen sink. These flanges keep the sink from falling through the hole cut in the countertop

Step 5

For Undermount Kitchen Sinks

Remove the sink from beneath the kitchen countertop by sliding it out.

For concrete or stone sink, you'll need power-cutting machinery to remove it.

For Topmount Kitchen Sinks

Push the sink from beneath and carefully lift from above the countertop.

Step 6

Clean the residue grime, caulking, and silicone to ensure a smooth kitchen sink installation.

It is recommended to use new fixtures when you are installing a new kitchen sink.

However, if you are considering using the existing fixtures, clean them before reinstalling them.

For expert advice on kitchen sink installation

New Kitchen Sink Installation

Before installing a new sink in your kitchen, make sure that the sink fits underneath/into the existing countertop. However, if you are using a new countertop, you must cut a custom hole for your new sink.

Step 1

For Undermount Kitchen Sinks

Slide the sink beneath the existing counters to make sure that the new sink will fit under the counter.

For Topmount Kitchen Sinks

Drop the sink over the top of your existing counters to confirm that the new sink will fit on the counter.

Step 2

Set the sink upside down to install fixtures and any other sink-related components.

Feed the supply tubing of the faucet through the rear end of the sink and seal the faucet. Screw the washers and mounting nuts to the bottom of the sink deck.

Step 3

Use the plumber's putty to fix the strainer/drain assembly to the sink. Firmly press to secure its position and remove any excess putty in the basin of the sink.

Use the rubber gaskets to tilt the sink on its side. It allows you to secure the flange to the underside of the drain.

Important Note: Always use high-quality putty for kitchen sink installation. It ensures the long life of the sink.

Step 4

If the kitchen sink has clips, turn the clips inside toward the bowl of the sink. And if the sink doesn't have any clips, simply drop/slide the sink over/beneath the counter.

Step 5

Use high-quality silicone caulk to create a watertight seal between the sink and the countertop. Clean off any excess caulk that oozes out during the kitchen sink installation.

For Undermount Kitchen Sinks

Apply an even amount of silicone caulk on the perimeter of the sink. Attach the sink to the countertop from beneath and use support to seal it in place

For Topmount Kitchen Sinks

Apply a bead of silicone caulk underneath the perimeter of the sink. Drop the sink over the countertop opening and attach it to the countertop.

Step 6

Connect the faucet to shut-off valves using braided stainless steel hoses or acorn-head supply tubes.

Attach the water sprayer hose to the threaded tailpiece of the faucet (optional). Reattach the water connections and connect the drain pipes.

Step 7

Your sink is now installed. Turn on the faucet and let it run for several minutes. Completely fill the sink with water.

Check for leaks around the faucet, plumbing, tubing, and drain locations.
