Is 18 Gauge Good Enough for a Kitchen Sink?

The gauge debate gets more attention than it deserves. Most of the difference shows up with heavy use.

What the sources say

Ruvati's page is the fullest we read, and it isn't neutral: Ruvati says its stainless collection has no 18-gauge sinks. Its section on the best gauge still calls 18 gauge often the best choice for most residential kitchen sinks. Its expert section favors 16 gauge, even for kitchens used only occasionally for heavy cooking. So read it with care.

Kohler builds its Task K-80084-1PC from 18-gauge steel, and sells it with a board, colander set and mat.

What else to read on the listing

Gauge is one line among several. Check the minimum cabinet, the bowl size and depth, and the sound line. The steel's grade is separate too, as our 304 page explains. A thick sink with no padding can still be loud. And if a listing gives no gauge at all, look for the maker's sheet before you decide.

When 18 is enough

• You mostly cook with light pots, and a dishwasher does the daily plates.
• You want a lighter sink, which Ruvati says is easier to handle.
• You like a specific sink, such as the Kohler Task 33^*.
• The budget matters, because Ruvati says 16 gauge is generally more expensive.

When to go to 16

• You use heavy pans, or put cast iron in the sink.
• You want one wide bowl.
• You don't want to think about dents later.

Ruvati says 16 gauge is less likely to dent or scratch. See 16 or 18 gauge for the side-by-side, and the best sinks for which picks are which.

Noise is a separate line on the sheet. Why a sink is loud covers that. If you like the ledge idea too, see workstation sinks.
