A standard double-bowl kitchen sink typically measures around 33 inches in length and 22 inches in width — that’s the typical kitchen sink size for most U.S. kitchens. Each basin (or bowl) is usually 14 inches wide, 16 inches long, and 7–10 inches deep, though large kitchen sink dimensions can run wider (up to 36 inches or more) for bigger basins or a low-divide design. Double sink dimensions vary by manufacturer, so it’s worth checking your specific model before ordering a new sink or countertop cutout.
Kitchen sink standard height isn’t about the sink itself — it’s set by the countertop, which typically sits 34–36 inches off the floor. A double sink in a bathroom follows different sizing altogether: a bathroom double sink (two separate basins in one vanity) is usually much smaller per bowl, often 16–20 inches wide each, since bathroom sinks don’t need the depth or capacity of a kitchen sink.
