Farmhouse Sink Sizes: Finding the Perfect Fit for Your Kitchen

Updated October 2026

I'm Clare, and I've been helping people choose sinks online since 2021. When someone asks me about size, it's usually because they're planning the cabinet themselves, so here's the short answer, plus how to measure so you get it right the first time.

The short answer: farmhouse sinks usually come in widths of 24", 27", 30", 33" and 36". The most common size is 33", which fits a standard 36" sink base cabinet. As a rule of thumb, choose a sink about 3" narrower than your base cabinet, and always check the sink's spec sheet for its minimum cabinet size.

Below you'll find a size chart, a quick way to measure, and our picks at every width.

Farmhouse Sink Size Chart

Sink width Typical minimum cabinet Best for Shop
24" to 27" 27" to 30" Small kitchens, apartments and second prep sinks 27" sinks
30" 33" Small to mid-size kitchens; a roomy single bowl 30" sinks
33" 36" Most kitchens; the most common size, single or double bowl 33" sinks
36" 39" Larger kitchens, double bowls and workstation sinks 36" sinks
37" and up 40" and up Big family kitchens and sinks with drainboards 37"+ sinks

Most farmhouse sinks measure 18" to 22" from front to back, with a bowl 8" to 10" deep. The cabinet sizes above are a guide only. Each manufacturer lists its own minimum cabinet size on the spec sheet, and handmade sinks can vary slightly, so go by the spec sheet and the actual sink.

Clare's tip: If you have the room, go big. I'll always choose the largest single bowl that fits. There's space for your biggest pots and for all the workstation accessories, and to me nothing says luxury in a kitchen like a big, beautiful sink.

How to Measure for a Farmhouse Sink

  1. Measure your sink base cabinet's width, side to side across the outside. Your sink should be about 3" narrower than that.
  2. Check the height. The apron replaces the top of the cabinet front, so there has to be room for it above the cabinet doors or drawer. Apron heights vary by brand, so check your sink's installation guide for how much clear space it needs.
  3. Measure front to back. Standard counters are about 25" deep, which fits most 18" to 22" farmhouse sinks with room behind for the faucet.
  4. Plan the apron overhang. Most aprons sit slightly in front of the cabinet face, but how far varies by brand and model, so check your sink's installation guide before your cabinet is built or cut.
  5. Wait for the sink before cutting. Handmade fireclay and metal sinks vary a little from piece to piece, so most manufacturers recommend cutting the cabinet and counter to the actual sink.

Clare's tip: Measure, then hire a pro. The biggest mistake I see isn't choosing the wrong size, it's skipping the professional installer. Farmhouse sinks are heavy, and the cabinet has to be cut and supported just right. A good installer will spot a problem before it costs you a sink.

Single Bowl, Double Bowl or Workstation?

Single bowl sinks give you one large basin for sheet pans, stockpots and roasting pans. They work at every size and are the most popular choice at 30" and 33".

Double bowl sinks split the basin so you can wash on one side and rinse or stack on the other. They feel cramped below 33", so we usually suggest them at 33" or 36".

Workstation sinks have a ledge inside the bowl that holds a cutting board, colander and drying rack, so the sink doubles as prep space. They make the most of every inch, which is why they're popular in both small and large kitchens.

Clare's tip: I've seen BOCCHI's workstation accessories in person, and they're the nicest I've come across. The cutting board is my favorite.

Already Have Cabinets? You Have Options

Installing a farmhouse sink in an existing kitchen usually means cutting down the cabinet front to fit the apron. If you'd rather not, a retrofit apron-front sink is designed to fit a standard 36" sink base with less cabinet work, like the Nantucket EZApron 33". Either way, we recommend a professional installer for any farmhouse sink. Fireclay and cast iron sinks are heavy and usually need extra support inside the cabinet.

Common Questions

What is the most common farmhouse sink size?

33" wide. It fits a standard 36" sink base cabinet and gives you room for a large single bowl or a double bowl.

Will a 36" farmhouse sink fit in a 36" cabinet?

Usually not. Most 36" farmhouse sinks need a cabinet of about 39" or more, because the cabinet sides need room around the sink. Check the minimum cabinet size on the sink's spec sheet.

What size farmhouse sink fits a 33" cabinet?

Usually a 30" sink. Some 30" sinks list a slightly larger minimum, so confirm on the spec sheet before you order.

How deep should a farmhouse sink be?

Most are 8" to 10" deep. A deeper bowl hides dishes and cuts down on splashing, while a slightly shallower bowl means less bending, which many shorter cooks prefer.

Can I put a farmhouse sink in my existing cabinets?

Yes. A cabinetmaker or installer can cut down the cabinet front to fit the apron, or you can choose a retrofit apron-front sink designed to fit a standard sink base.
