How Thick Should a Stainless Steel Sink Be?

When shopping for a stainless steel sink, one of the most important factors to consider is thickness. Unlike other materials, stainless steel is measured by gauge—a numbering system that can be confusing at first. The lower the gauge, the thicker the steel. Choosing the right thickness ensures your sink is strong enough to resist dents, reduce noise, and handle daily use. But how thick should your stainless steel sink really be?

Most residential stainless steel sinks range between 16-gauge and 22-gauge. A 16-gauge sink is about 1.5 millimeters thick, while a 22-gauge sink is thinner at about 0.8 millimeters. The thicker the steel, the more durable the sink will be. If you cook often, use heavy cookware, or want your sink to last for decades, a thicker option like 16- or 18-gauge is ideal. Thinner sinks are more budget-friendly but may not hold up as well over time.

Noise is another factor to think about. Thicker sinks naturally absorb more sound, making them quieter when washing dishes or running water. Many high-quality stainless steel sinks also come with sound-deadening pads or undercoatings, which further reduce vibration and noise. If you’ve ever used a flimsy sink that rattles loudly, chances are it was a thinner 22-gauge model without proper insulation.

Durability and resistance to dents also depend on thickness. A 16-gauge sink can withstand heavy pots and pans without bending or denting, while thinner options are more prone to warping under pressure. For homeowners who want a sink that will handle tough daily use, investing in a lower-gauge (thicker) sink pays off in the long run.

At I Hate My Sink, we recommend 16- to 18-gauge stainless steel sinks for the perfect balance of strength, quiet performance, and value. These sinks are thick enough to handle the demands of a busy kitchen while still offering a sleek, modern look. Choosing the right thickness ensures you’ll enjoy your sink for years without worrying about dents, noise, or premature wear.
