Farmhouse Sink Sizes and the Cabinet Each One Needs
Plan on a cabinet about 3 inches wider than the sink. That's the common advice from sellers and from KRAUS's own older guide. Some makers print smaller figures, so read the sheet for the exact sink before you build around it.

In short
Common farmhouse sinks come in 30, 33 and 36 inch widths. A cabinet about 3 inches wider than the sink is the usual advice from The Sink Boutique and Signature Hardware. Makers vary: Ruvati asks for 36 inches for its 33-inch class sink, BOCCHI's listing says 33 for a 30-inch sink, and KRAUS's 2020 manual gives a 33 minimum for its 33.

Apron sinks are harder to size than regular ones, because the sink becomes part of the cabinet front. Here's what makers and sellers actually say.
Sizes and cabinets, as printed
| Sink | Outside size | Cabinet asked for | Who says so |
|---|---|---|---|
| BOCCHI Classico 30 | 30 × 18 × 10 in | 33 in | Retailer listing |
| KRAUS KHF200-30 | 30 in class | 30 in | KRAUS 2020 manual |
| KRAUS KHF200-33 | 32-7/8 × 20-3/4 × 10 in | 33 in, or sink plus 3 in | KRAUS 2020 manual, 2017 guide |
| Ruvati RVL2300WH | 32-3/4 × 20-1/4 × 10-1/4 in | 36 in | Ruvati |
| KRAUS KHF200-36 | 36 in class | 36 in | KRAUS 2020 manual |
| Kohler Whitehaven K-6489 | 35-3/4 in nominal | 36 in apron base | Kohler |
Where the sources disagree
The Sink Boutique and Signature Hardware both say about 3 inches wider. KRAUS's 2017 guide says the same: farmhouse base cabinets should be 3 inches larger than the actual sink. KRAUS's 2020 manual then lists a cabinet the same size as the sink class. We can't tell you why they differ.
Ruvati says more plainly why this matters. It says a 33-inch cabinet leaves no room to adjust its 33-class sink, and it wants 36. And BOCCHI's listing warns that dimensions may vary because of firing, which makes clearance more useful with fireclay.
How to measure for an apron sink
Measure the cabinet width
Measure the base cabinet from side to side, and compare with the sheet.Note the height of the door tops
Most farmhouse sinks are about 9 to 10 inches deep, so the top of your cabinet front is going to change.Check inside
The sink rests on supports in there, and they need room next to the drain.Wait for the sink
Have the real sink on site before the counter is cut, especially with fireclay.
Which one should you pick?
For a 36-inch base, pick the KRAUS KHF200-33* in steel or the Ruvati RVL2300WH* in fireclay. For a 33-inch base, the BOCCHI Classico 30* is the one we can point to. See the farmhouse page and the fireclay page for the comparison.
If your cabinet is staying put, read existing cabinets next. For regular sinks, what size fits has the same check. And if you've measured a 30-inch cabinet, see the 30-in-30 answer.
Asked before buying
What is the most common farmhouse sink size?
We don't have figures on what sells most, so we won't name one. Yale Appliance gives 24, 30, 33 and 36 inches as common sink widths in new construction, and KRAUS sells its farmhouse sink in 30, 33 and 36 inch versions. Signature Hardware says farmhouse sinks range from about 20 inches to 60 or more.
What size farmhouse sink fits a 36-inch cabinet?
Usually a sink of about 33 inches. Ruvati gives 36 inches as the minimum for its 32-3/4-inch RVL2300WH. Kohler's Whitehaven is nearly 36 inches wide on the outside and is still listed for a 36-inch apron base, so check the exact model. That big a difference shows why the sheet matters.
How tall is the apron?
A full apron is usually about 10 inches tall, Signature Hardware says, and a retrofit apron is about 3 inches shorter. The Sink Boutique says most farmhouse sinks are about 9 to 10 inches deep. The BOCCHI 30 and the KRAUS KHF200-33 are listed at 10 inches tall.
