Kitchen Sink Size Standards - Width, Depth And Cabinet Dimensions

When designing or remodeling a kitchen, choosing the right sink is an important decision. The size and dimensions of your sink will impact the workflow and functionality of your kitchen. Knowing standard kitchen sink widths, depths, and how they fit with cabinet sizes will ensure your new sink is well-suited for your space.

Standard Single Bowl Kitchen Sink Widths

For a single bowl kitchen sink, the most common width is 22 inches. This size allows the sink to fit well within a standard 24-inch sink base cabinet. Wider single bowl sinks are available, such as 25 inches, but they may limit your faucet placement or counter space on either side.

Narrower 18-inch and 20-inch single bowl sinks are also options for small spaces. However, the reduced width may make washing larger pots and pans more difficult.

Advantages of a 22-Inch Wide Single Bowl Sink

• Fits with standard 24-inch sink base cabinet
• Allows adequate room for washing dishes and produce
• Leaves counter space on either side for meal prep

Disadvantages of Smaller or Larger Sink Widths

• 18-20 inches may be too narrow for some uses
• 25 inches limits counter space around sink

Standard Double Bowl Kitchen Sink Widths

For a double bowl kitchen sink, the standard width is 33 inches. This size fits well within the typical 36-inch wide sink base cabinet often used in kitchen designs.

Narrower 30-inch or 32-inch double bowl sinks are sometimes used in small kitchens. However, the divided bowls will be quite narrow. Wider than 33 inches will likely not fit within a standard cabinet.

Benefits of a 33-Inch Wide Double Bowl Sink

• Fits a 36-inch sink base cabinet nicely
• Provides two roomy bowls for washing and rinsing
• Allows space between bowls to add a dish drying rack

Drawbacks of Smaller or Larger Double Bowl Sinks

• 30-32 inch widths have narrow bowl space
• Wider than 33 inches may not fit cabinet well

Standard Kitchen Sink Base Cabinet Dimensions

The standard kitchen sink base cabinet is 36 inches wide and 34.5 inches tall. This size can fit most double bowl sinks. For single bowl sinks, a narrower 24-inch sink base cabinet is also commonly used.

Having the properly sized cabinet to fit your sink choice is important for functionality and visual appeal. A sink base cabinet that is too small will not allow the sink to sit properly. Overhang on the sides should be minimized.

Standard Sink Base Cabinet Widths

• 36 inches - fits most double bowl sinks
• 24 inches - fits most single bowl sinks

Standard Cabinet Height and Depth

• 34 1/2 inches tall
• Depth around 23-24 inches

Typical Kitchen Sink Depths

Kitchen sink depths often range from a minimum of 7 inches up to 10 inches or more for deeper models. The typical range for most residential kitchen sinks is 7 to 9 inches deep. Here are guidelines for choosing sink depth:

• 7-8 inches - shallower depth for smaller spaces
• 9 inches - standard medium depth for most kitchens
• 10+ inches - provides more room for washing large pots

The depth you choose impacts the usability of the sink. Deeper sinks allow more room for washing dishes by hand. Shallower sinks take up less counter space. Select a depth in balance with your kitchen work flow and space.

Choosing the Right Kitchen Sink Size

When selecting a new kitchen sink, be sure to consider:

• Existing cabinetry dimensions or new cabinet plan
• Single or double bowl preference
• How the sink will be used - washing dishes, food prep, etc.
• Allowing proper clearance for faucets and backsplashes

Carefully measuring your existing cabinet with framing is recommended if replacing a sink. Coordinating with cabinet sizes ensures your new sink will fit properly and function as needed.

Metric Kitchen Sink Size Conversions

While most kitchen sinks use inch measurements, metric sizes are also available. Common metric sink dimensions include:

• Widths: 560mm, 760mm, 860mm
• Depths: 180mm to 250mm

10 mm is approximately 0.4 inches. Converting between metric and imperial units is straightforward.

Following standard kitchen sink width and depth guidelines will ensure a well-fitted, functional sink. Coordinating your sink size with cabinet dimensions is key for a seamless installation.

While standard sizes exist, minor variations are also available. Be sure to fully measure your existing cabinetry or check cabinet plans before selecting a new sink. Carefully planning your kitchen sink size will result in a beautiful, efficient workspace.
