16 vs 18 Gauge: What the Number Means in Your Kitchen

A lower gauge number means thicker steel. Take 16 gauge for a big single bowl and heavy pans. Take 18 gauge if your use is ordinary and you want to spend less. Don't stop at the number: read the line about pads too.

In short

16 gauge is thicker than 18. Ruvati lists 0.063 inches against 0.047 inches and says the thicker steel is less likely to dent or scratch. It also calls 18 gauge often the best choice for most home kitchens. Kohler builds its Task from 18 gauge. Take 16 for big bowls and heavy pans, and look for pads either way.

The short version: take 16 gauge if you're buying a big single bowl and you use heavy pans. Otherwise, 18 gauge is a sensible way to spend less.

The two side by side

	16 gauge	18 gauge
Thickness, per Ruvati	0.063 in (1.59 mm)	0.047 in (1.2 mm)
Dents and scratches, per Ruvati	Less likely	May not handle heavy use as well
Handling, per Ruvati	Heavier	Lighter and easier to handle
Price, per Ruvati	Generally more	The budget option
Sinks on this site	KRAUS KHU100-32, Ruvati RVH8300 and RVM4350, Delta Lorelai	Kohler Task 33

One thing to know about that source: Ruvati says its stainless collection has no 18-gauge sinks, and its page argues both ways. Its "best gauge" section calls 18 gauge often the best choice for most home kitchens, and its expert section favors 16. We think both are fair, depending on the kitchen.

Where the difference shows

Big single bowls. A wide bottom with nothing to brace it is where thicker steel makes the most sense, and it's why our main pick is 16 gauge. The KRAUS KHU100-32^* has a bowl 30 inches wide.

Heavy pans. If you drop cast iron into the sink, you want the thicker steel. Use a sink grid too.

Ordinary use. A kitchen with light pots and a dishwasher doing most of the work won't call on much of that extra thickness. The Kohler Task 33^* is 18 gauge, and Kohler pairs it with a full set of workstation accessories.

Noise is a separate line

Sellers often pair thickness with quiet. Ruvati says 16 gauge offers better noise reduction. But makers list sound control as its own feature:

KRAUS lists NoiseDefend undercoating and sound dampening pads.
Ruvati lists heavy-duty sound guard padding and undercoating.
Delta lists pads over more than 80 % of the sink.
Elkay's sheet for its #22-gauge Dayton double lists undercoating on the bottom of the bowl to dampen sound.

So don't read gauge as a noise rating. See why a sink is loud for more.

Take 16 if, take 18 if

Take 16 gauge if you cook with heavy pans, want a wide single bowl, or don't want to think about it again.

Take 18 gauge if the budget matters, your use is light, or you like a specific sink that happens to be 18, like the Kohler Task.

Be careful with anything thinner on a main kitchen sink. Elkay's budget Dayton sheet lists #22 gauge, which is fine for a plain swap in a rental but isn't what we'd pick for heavy pans.

Gauge tells you about thickness only. The steel's grade is another line, covered in 304 stainless steel. For the full list, see the best sinks, or check the 18 gauge question if that's what you're down to.

Asked before buying

Is a lower gauge better for a sink?

A lower gauge is thicker, and Ruvati says thicker steel is less likely to dent. It's better if your pans are heavy or your bowl is big. It also costs more. For light use the difference may not matter, and Ruvati itself calls 18 gauge often the best choice for most home kitchens.

How thick is 16 gauge stainless steel?

Ruvati lists 16 gauge as 0.063 inches (1.59 mm) and 18 gauge as 0.047 inches (1.2 mm). Other sellers print slightly different figures. What matters is the direction: the lower the number, the thicker the steel.

Is 16 gauge quieter than 18 gauge?

Ruvati says 16 gauge offers better noise reduction, but makers also list pads and undercoating as separate features that do that job. So a thick sink with no padding isn't what you want. Check for both lines on the spec sheet.

What about 20 or 22 gauge?

They're thinner still. Elkay's sheet for a Dayton double bowl lists #22 gauge, on a budget line. It can do for a rental or a light-use kitchen, but we wouldn't choose it for heavy pans. Always check the gauge on the listing for the exact model.
