What Is the Standard Double Bowl Sink Size?

Common Dimensions in 2025

The most common standard size for a double bowl kitchen sink in 2025 remains 33 inches wide by 22 inches front-to-back.

This size typically accommodates two equally sized or offset bowls, making it ideal for average-sized kitchens.

You may also find variations such as:

32″ x 21″
36″ x 22″
36″ x 20″
38″ x 22″ (for larger installations)

The interior depth usually ranges from 8 to 10 inches, though deeper basins up to 12 inches are becoming more popular in work-focused kitchens.

Minimum Cabinet Requirements

To properly install a double bowl sink, your base cabinet must be wide enough to support it. As a rule of thumb:

For a 33-inch wide sink, you need at least a 36-inch base cabinet.
For larger sinks (36″ or 38″), opt for a 39″ to 42″ base cabinet.
Always leave 2–3 inches of space on each side for mounting and plumbing clearance.

33 vs 36-Inch Cabinet Fit

The 33-inch sink is considered the sweet spot—it fits most base cabinets without modifications.

However, if you’re working with a 36-inch cabinet, you can comfortably choose a slightly larger sink (up to 34 or 35 inches wide) or add workstation features like a cutting board or drying rack.

For smaller kitchens with 30-inch base cabinets, a double bowl sink can still work, but you’ll need a reduced-width version, such as a 30″ x 18″ or compact 27″ model.

Double Bowl Sink Styles and Sizes

Equal vs Unequal Bowl Configurations (60/40, 50/50)

Double bowl sinks come in two main configurations:

50/50: Both bowls are of equal size—ideal for homeowners who split their sink use evenly between tasks.
60/40 or 70/30: One larger and one smaller bowl—for those who want more washing space while keeping a separate area for prep or disposal.

60/40 sinks are increasingly popular in 2025 due to their ergonomic utility.

Compact and Large Double Bowl Options

Not all double sinks are full-size. Here are a few modern variations:

Compact double sinks: Typically 27″ to 30″ wide—great for apartments or smaller kitchens.
Oversized double sinks: Extend up to 48 inches wide and are common in luxury or professional kitchens.

Choosing between them depends on your cabinet space and kitchen workflow.

1.5 and Triple Bowl Alternatives

1.5 bowl sinks: Include one full-size basin and a smaller, shallower side bowl—perfect for food prep or rinsing.
Triple bowl sinks: Have three compartments—usually one large central bowl flanked by two smaller ones. These are less common but excellent for multitasking in larger kitchens.

What Is a Double Bowl Sink Used For?

Everyday Use Cases

How Dishwashers Have Changed Their Role?

With dishwashers now common in nearly every home, many wonder if double sinks are still relevant.

In 2025, double sinks are more flexible than ever, often doubling as workstation sinks that include:

Drying racks

Colanders

These upgrades make them even more practical, even in dishwasher-equipped homes.

Best Materials for Double Bowl Kitchen Sinks

Stainless Steel

Still the most popular choice, stainless steel sinks offer:

Excellent durability
Resistance to heat and stains
Easy cleaning and maintenance

For double bowl sinks, choose a 16- or 18-gauge stainless steel to reduce noise and increase strength.

Enameled Cast Iron

These sinks bring a classic, high-end look:

Coated with a layer of porcelain enamel
Extremely durable and resistant to chipping
Heavier and require strong cabinet support

They’re ideal for traditional kitchens or farmhouse-style layouts.

Fireclay & Granite Composite

Fireclay sinks are crafted from molded ceramic and fired at high temps—offering a glossy, timeless look.
Granite composite sinks are made from a mix of granite stone and resin—providing a modern, matte finish with excellent scratch resistance.

Both materials are stylish and hard-wearing, though heavier than stainless steel.

Copper and Specialty Materials

Copper is a statement material known for its:

Natural antimicrobial properties
Unique aging (patina)
High cost and maintenance

If you’re looking to add character and warmth to your kitchen, a copper double bowl sink can be a stunning centerpiece.
