Prep sink
A prep sink is a smaller secondary sink used for food preparation, typically placed in a kitchen island or wet bar.
Why it matters
It keeps the main sink available for dishwashing while someone preps food at the island, improving kitchen workflow during busy cooking.
Where people get this wrong
A prep sink needs its own drain, water supply, and venting. It adds plumbing cost and complexity, especially in an island without a nearby wall.
Real-world example
The island has a small 15-inch single-bowl prep sink for washing vegetables while the main sink is full of dishes.
Where this hits your build
This hits during the selection phase. Choices here affect layout, daily use, and maintenance. Samples and measurements matter more than catalog photos.
