What gauge stainless steel sink is best? This article answers this question by determining the best and recommended gauge stainless steel sink.

What is the Gauge?

You may have seen this term in stainless steel appliances. The gauge is the thickness of stainless steel material used when manufacturing the kitchen sink.  Gauge is measured differently from other measurements because the lower the number, the thicker is the gauge.

Most of the quality kitchen sink has 16 or 18 which are very heavy to resist damage, rust, and noise. A higher number shows low quality like 22 and above which are thin gauge stainless steel.

What Gauge Stainless Steel Sink is Best? The best gauge to have is between 16 and 18 stainless steel kitchen sink. This gauge is the best material because they are durable and less prone to denting or bowing. 16 and 18 will handle daily usage of the kitchen sink without any problems. This gauge is recommended for household sinks.

The process of manufacturing stainless steel involves a mixture of other alloys to achieve the quality stainless steel we see. Nickel, copper, Titanium, and Molybdenum are added to enhance the structure of final stainless steel.

16 Gauge vs 18 Gauge Stainless Steel Sink

If you see labeling like 18/10 or also known as 304 means the percentage of chromium and nickel in the steel. The 16 gauge is better than the 18 gauge because of the lower the number, the thicker the kitchen sink.

As a quick side note, 304 grade is a better grade than 430 on the other end of the stainless spectrum, so keep that in mind if you see the other number when buying a sink. The 304 is the most durable composition and will last longer with a better-looking finish for longer. You may start to see rust on the 430 as it ages, and the durability will vary as you continue on the spectrum between 304 and 430.

16 gauge is quieter than the 18 gauge due to its thickness. A drop of metal in the sink can be different between the two.

Both 16 and 18 gauge are used and recommended by reputable kitchen sinks brands like Blanco, Kraus, and Kohler. These stainless steel are standard with the perfect size for home use and also affordable. The thicker the stainless steel sink is, the most costly it is.

Should I get a 16 or 18 gauge sink?

Cheap brands may have 16 gauge kitchen sink but the style and craftsmanship are poor. Between the two gauges, it’s better to choose any but from a reputable brand like Blanco.
