Step 3: Design the Base Cabinet

If you already haven’t any base cabinet or if you haven’t designed for it, you can choose any size sink based on your kitchen size and according to your choice. You’ll just require creating a base cabinet which should be wide enough to fit the sink.

To design your base cabinet, you can discuss with the cabinet maker or designer to be ensured what size cabinet will work best and will make everything easier for you.

You should focus on what dimensions of the sink your existing cabinet can fit and how you can customize it to accommodate the sink you install.

The maximum side-to-side length of your sink should be about ¼-inch less than the inner width of the cabinet.

The maximum height of your sink should be the distance of the top of the cabinet doors to the top of the cabinet base.

If you intend installing a farmhouse sink in existing cabinets with replacing the old sink, first measure the old farmhouse sink and then remove the sink to measure the existing cutout of the countertop.

If you’re going to install new stainless steel farm sink along with new countertops, you have to measure the sink before you cut a hole in your countertop.

For installing the new sink on the new countertop, first decide how you like your countertop cut.

You have two options:

1. Exposed edge option. You can install the sink so that you can see the edges of the sink.

If the template comes with the sink, place it on your countertop.  Then trace the outline with a pencil. It’ll remove the need to do much extra work of measuring.

Using a sharp saw blade, cut the cabinet carefully on the traced line.

Make your own template if your new sink does not come with it. To make your own template-

Lay the sink on cardboard (upside down on your countertop) and trace the outline of the sink with a marker or pencil.


Measure your sink and mark the countertop using the measurements before you cut a hole in your countertop.

FAQ Regarding Installation of Stainless Steel Farmhouse Sink

Why is the installation of farmhouse or apron front stainless steel sink different than traditional sink?

Farmhouse style sinks feature a large and exposed front panel that prolongs from the forefront of the sink down into the front edge of the base cabinet.

As traditional kitchen sink, farmhouse sink can’t be installed to the countertop. Because of the weight, this type of sinks cannot sit on the inside frame of the base cabinet. They are designed to sit slightly to the front of the cabinet around so that water flowing down to the front if the sink directly land to the floor instead of running on and damaging the cabinets.

A platform requires to be built inside the base cabinet that accommodates the sink weight.

In general, farmhouse sinks are also set up under the level of the countertop. As a result, the counter slightly overhangs the sides of the sink that makes it easy to clean off the water from the counter straight into the sink.

Top mount vs. undermount sink – Which is easy to install?

Topmount kitchen sink (also known as Drop-in or self-rimming or overmount sink) drops into a hole cut out of the countertop. The sink lip or rim of the topmount kitchen sink rests on the top edge of the countertop. You can set up the kitchen sink faucet directly on the sink ledge.

The top mount (drop in) sink is easier to install than undermount kitchen sink as top mount farmhouse sink size is not limited by the walls of the cabinet.

Undermount sink features no lip or rim. This seamless style makes cleaning easier and it also takes up less counter space than a top mount sink of the same size. However, undermount farm sink installation is harder than a drop in kitchen sink installation.

Can a top mount (drop in) sink be installed as an undermount sink?

A top mount or drop in apron sink can be installed under the countertop to fit like an undermount sink. However, there is disadvantage to this installation. Water may easily spill over the sides of the sink if the sides aren’t properly sealed.
