When choosing a stainless steel kitchen sink, one of the most important specifications to understand is the gauge — a measurement that indicates the thickness of the stainless steel sheet used to make the sink. The gauge directly affects the sink’s durability, sound performance, and overall quality.
In this guide, Shunhan Kitchen & Bath Technology Co., Ltd. explains what sink gauge means, how to compare different gauges, and which thickness provides the best performance for long-term use.
The term “gauge” refers to the thickness of the stainless steel used in the sink.
It’s measured inversely — the lower the gauge number, the thicker and stronger the steel.
| Gauge | Approx. Thickness (mm) | Quality Level |
|---|---|---|
| 16 Gauge | 1.5 mm | Heavy-duty, premium quality |
| 18 Gauge | 1.2 mm | Standard residential quality |
| 20 Gauge | 1.0 mm | Light-duty, budget level |
| 22 Gauge | 0.8 mm | Thin, not recommended for frequent use |
So, a 16-gauge sink is thicker and more rigid than an 18- or 20-gauge sink. The difference might seem small, but it significantly affects the feel, sound, and lifespan of the product.
Both 16-gauge and 18-gauge sinks are commonly used in modern kitchens. The right choice depends on the application and performance expectations.
| Feature | 16 Gauge Sink | 18 Gauge Sink |
|---|---|---|
| Thickness | 1.5 mm | 1.2 mm |
| Strength | Very high, dent-resistant | Good for household use |
| Sound Insulation | Excellent with fewer vibrations | Moderate, may require more padding |
| Price | Higher due to thicker material | More affordable |
| Weight | Heavier | Lighter |
| Best For | Premium homes, commercial use | Residential kitchens |
16-gauge stainless steel sinks are the most durable, while 18-gauge sinks offer an excellent balance of performance and value. Both are ideal for daily kitchen use, especially when crafted from SUS304 food-grade stainless steel like Shunhan’s products.
Thicker sinks are more resistant to dents, warping, and vibration. They handle heavy pots and daily use without flexing, maintaining a solid and quiet feel.
A thicker gauge sink transmits less sound. Combined with sound-deadening pads and anti-condensation coating, it ensures a quieter washing experience.
While corrosion resistance depends primarily on the steel grade (e.g., SUS304), thicker material provides additional surface protection against wear and tear.
Thicker sinks are heavier, which may slightly increase installation effort. However, they provide better countertop stability and longevity.
Though slightly more expensive, thicker gauges provide better return on investment due to their long lifespan and lower maintenance requirements.
Choose a 16-gauge sink if you value durability, sound control, and a solid feel.
It’s ideal for:
Luxury residential kitchens
Commercial kitchens or food preparation areas
High-traffic environments where the sink is used frequently
Customers seeking a premium, professional-grade finish
At Shunhan, our 16-gauge stainless steel sinks are made with SUS304 food-grade steel, precisely brushed for a sleek look, and reinforced with soundproofing pads for ultra-quiet operation.
An 18-gauge sink is slightly thinner but still provides reliable performance for most homes.
It’s ideal for:
Standard residential kitchens
Cost-conscious buyers
Multi-unit housing projects or apartments
Occasional or moderate use environments
Shunhan’s 18-gauge sinks maintain exceptional quality, combining durability, corrosion resistance, and refined aesthetics — perfect for everyday use without excess cost.
Sinks made from 20- or 22-gauge steel are more affordable but have drawbacks:
Easier to dent or bend under heavy use
Noisier due to thin metal walls
More prone to vibration and “tinny” sound
Shorter lifespan, often requiring earlier replacement
For professional results and long-term reliability, Shunhan does not recommend or manufacture sinks below 18 gauge for kitchen use.
While gauge is crucial, several additional elements affect the overall performance of a stainless steel sink:
Material Grade: Always choose SUS304 or SUS316 stainless steel for corrosion resistance and hygiene.
Surface Finish: Brushed and satin finishes hide scratches better than mirror finishes.
Anti-Condensation Coating: Prevents moisture buildup beneath countertops.
Soundproof Padding: Reduces noise and vibration during washing.
Precision Welding & Polishing: Ensures seamless corners and a smooth appearance.
Shunhan integrates all these factors into every product to provide customers with lasting value and comfort.

So, what gauge is best for a stainless steel sink?
For most kitchens, 16 or 18 gauge stainless steel is the ideal choice.
16-gauge sinks deliver superior strength, sound absorption, and premium quality.
18-gauge sinks offer a balance of performance, durability, and value.
Avoid thinner options below 18 gauge, as they compromise longevity and stability.
For reliable, corrosion-resistant, and beautifully crafted sinks, choose Shunhan stainless steel sinks, made from SUS304 food-grade material with precision engineering for lasting quality.
