Common Sink Sizes, Options, and Applications
Some sink sizes, like vanity sink sizes, vessel sink sizes, and single bowl sink sizes, may differ from the norm, but you can generally use the guidelines above to measure your new sink. More common types of sinks, like rectangular kitchen sinks and rounded bathroom sinks, have more predictable common sink sizes.
The sink sizes below are some of the more popular sink base sizes for kitchens, bathrooms, and laundry rooms:
Bathroom sinks tend to be smaller than a kitchen sink or laundry room sink, so you'll usually find smaller sizes when searching for bathroom sinks. One of the smallest is a 16-inch sink, usually reserved for a small bathroom's limited counter space.
The 16-inch sink is also more common to find with rectangular undermount sinks than a drop-in sink. You'll notice that the sink sizes may vary a little under or over 16 inches, and their depth and width can range significantly to fit your space.
