Essential Guide to Kitchen Sink Dimensions and Standard Sizes
When remodeling a kitchen or replacing a worn-out sink, choosing the right size is crucial for functionality and seamless coordination with cabinetry. With so many options available, it's important to understand standard kitchen sink dimensions to find the perfect fit.
Typical Kitchen Sink Sizes
Kitchen sinks come in a range of shapes and configurations, but there are some standard widths and depths to be aware of.
Single Bowl Kitchen Sinks
For a classic, versatile design, single bowl sinks are most popular for residential kitchens. The most common sizes are:

- 33" x 22"
- 30" x 22"
- 25" x 22"
Depth is an important consideration for function - deeper 10"+ sinks allow washing large pots and pans. Undermount and topmount sinks may have slightly different dimensions.
Double Bowl Kitchen Sinks
Double bowl sinks provide a divided workspace for multitasking. Typical sizes are:
- 33" x 22"
- 30" x 22"
Double bowl sinks often have two equal-sized basins, or a large and small basin. As with single bowls, maximize depth where possible.
Other Size Options
While less common, more petite sinks for tight spaces or large single bowls for versatility are also available. Triple bowl and bar/prep sinks suit specific needs.
Factors That Impact Kitchen Sink Size Selection
Several considerations go into choosing the right kitchen sink size for your space and needs.
Existing Cabinetry and Countertops
Standard base sink cabinets are usually 36", 33", or 30" wide. The existing cabinetry footprint and countertop material affect which sizes can be accommodated.
For undermount sinks, the countertop cutout is typically 1-2" smaller than the overall sink dimensions to allow a reveal. Larger sinks may require cabinet modifications.
Type of Installation
Undermount sinks installed below counter level need to coordinate with the countertop cutout size. Top mount or drop-in sinks sit above.
Design and Function Preferences
Consider if a single or double basin best suits your needs. Prioritize depth for washing large items. Also factor in clearances for faucets and other fixtures.
How to Determine the Right Sink Size
Follow these tips for choosing a correctly sized kitchen sink:
Measure Existing Cabinets and Countertops
Carefully measure your existing sink base cabinet and countertop openings. This verifies what dimensions can be accommodated.
Consider How You Use the Sink
How you utilize your kitchen sink - washing dishes, food prep, entertaining, etc. - impacts whether a single or double bowl is better suited.
Pick a Size Within Your Cabinet Footprint
Select a sink sized 1-2" smaller than cabinet width for undermount reveal. Avoid sizes that require major cabinet alterations.
Coordinate With Countertop Fabrication
Confirm cutout dimensions with countertop fabricator for smooth undermount installation. Allow room for faucets and backsplash.
With standard kitchen sink sizes ranging from 25" to 33" wide, carefully measure your existing cabinetry and countertops first. Also factor in your workflow and design needs before selecting basin dimensions.
Paying attention to measurements during kitchen remodeling ensures your new sink not only fits, but optimizes function.
