Question: are all sinks the same size?
Answer: Choosing a Sink The most common sink sizes are 24, 30, and 33 inches. Smaller homes and condos will likely go with the 24-inch size, small yet functional enough to wash pots and pans. Common 24-inch sink shapes are a square and D-bowl. Sinks 24 inches wide must sit in at least a 27-inch sink base cabinet.
