What are the Standard Kitchen Sink Dimensions and Sizes?
When remodeling a kitchen or building a new home, choosing the right sink is an important decision. The standard dimensions and sizes for kitchen sinks provide a helpful starting point. With so many shapes, sizes, and configurations available, understanding the typical kitchen sink widths, lengths, depths, and more creates a baseline for finding the perfect model for your needs.
Whether you prefer an efficient single bowl, generous double bowl, or stylish apron-front sink, pinpointing the ideal size depends on careful measurement of existing spaces, projected use, and personal priorities. Arm yourself with a knowledge of common industry standards, and you’ll be ready to select the ideal kitchen cleanup station.
Single Bowl Kitchen Sink Dimensions
Single bowl sinks are a popular choice that offer versatility for handling dishes of all kinds. The most common interior sink basin dimensions for a single bowl kitchen sink are 30 inches wide and 22 inches front-to-back. Standard single bowl sink widths range from compact 18-inch models to larger bowls up to 33 inches across. Farmhouse and apron-front style sinks are available in extended lengths from 36 to 48 inches.
When planning sink size, remember that single basin sinks may be square or rectangular. Length often matches width to form a square shape, but rectangular sinks with different length and width measurements are also common.
Standard Sink Depths
Standard single bowl kitchen sink depths are 8 or 10 inches. A deeper 10-inch sink bowl provides more room for washing pots, pans and other cumbersome dishes. Shallower sink depths around 7 to 9 inches are typical for apron-front farmhouse sinks, which compensate with extended lengths.
Shape Options
In addition to rectangular and square bowls, creatively shaped single basin sinks include round, oval, and models with curved or angled corners. But for maximum usage, standard rectangular sinks are most popular.
Size Considerations
When determining single bowl kitchen sink dimensions, account for how many people will use the sink and the types of items you’ll wash. If you regularly hand wash large pots and pans or canning jars, consider a deeper 10” sink. For an active cooking household, larger 33” sink lengths offer more workspace. When replacing an old sink, double check measurements of the existing cutout before selecting a new sink size.
Double Bowl Kitchen Sink Dimensions
To increase efficiency, many homeowners opt for a double bowl kitchen sink. The most common double bowl sink width is 60 inches, divided into two 30-inch bowls side-by-side. But layouts that include one main 30-35 inch basin next to a smaller 20-25 inch secondary sink are also popular.
Varying Lengths and Depths
Double bowl sinks generally have the same 8-10 inch depth options as single bowl models. And each basin typically measures 30 to 33 inches in length from front to back. One benefit of a divided sink is keeping clean dish draining space separate from messy food preparation. Many cooks appreciate double sinks, but single bowls work well too.
Deciding Between Double vs. Single Bowl
When debating between a double vs single bowl sink, consider your needs. A divided sink helps streamline workflow and keeps pre-wash scraps and debris contained. But a spacious single basin accommodates oversized pots and awkward shaped cookware that a double sink may not. Let your cooking habits guide the right setup for you.
Sink Cabinet Dimensions
Most kitchen sinks have a base cabinet installed beneath them. The most common width for a sink base cabinet is 36 inches. But smaller 33-inch and 30-inch sink base cabinets are also widely available options, especially in compact kitchens.
Standard height for a sink base cabinet is 34.5 inches from floor to countertop. When installing your sink, make sure to leave clearance for fixtures like faucets, soap dispensers, and handles. Also account for sink drain pipes, shut-off valves, and garbage disposals if equipped.
Tip for Aligning Edges
For a streamlined look, align the front edge of the sink base cabinet with the front rim of the sink. This makes the countertop appear wider and creates visual harmony.
Choosing the Right Kitchen Sink Drain Size
Kitchen sink drains are typically 3.5 inches in diameter. This accommodates most standard residential garbage disposal units. For heavy use kitchens, a larger 4-inch drain may be preferable.
When selecting a new kitchen sink, arm yourself with knowledge of common interior basin dimensions. A standard 30 x 22-inch single bowl or 60-inch double bowl sink works for many kitchens. Remember to account for sink depth, often 8 or 10 inches. Most sinks fit in a 36-inch wide base cabinet. And standard drain size is 3.5 inches. Knowing typical sink sizes and measurements provides a baseline to choose the perfect model to match your space and needs.
