18 gauge vs. 16 gauge stainless steel sink

Are you setting up a new kitchen? One of the most important parts to consider is the sink, which will be used several times a day. That’s why you must pick the best one. The best doesn’t necessarily mean the most expensive or the most popular. It has to be the best suited for your kitchen.


The main differences between 16-gauge and 18-gauge stainless steel sinks are their thicknesses and therefore, their durability. When you’re buying a stainless steel sink, you want to avoid the mistake of not considering the size you’re getting.

In this article, we also look at the following topics:

  • Whether these sinks scratch
  • What are the advantages and disadvantages are for each type?

Let’s take a look at all the options!

New sink


The gauge is a tricky term that comes up when discussing steel fittings. It refers to the thickness of the steel. Unlike other units of measurement, the gauge gets thicker and better as the number gets lower. For instance, 18 gauge is thicker than a 23 gauge sink.

For some fittings, it is suited to have a thinner gauge. Other functions require something thicker for durability.

In kitchen sinks, it is considered better to have something of a lower gauge and thus higher thickness owing to a couple of factors listed below:

18 gauge steel sink
  • Noise: a thicker steel basin will reduce the amount of noise your dishes create while you do the washing.
  • Commercial use: If they are installed in hotel kitchens, restaurants, and other commercial spaces, you will need a lot more durability on your side. It is because heavy utensils will be placed in these sinks and for longer amounts of time as well. That’s why these sinks are typically in the 14 to 16-gauge range.
  • Garbage disposals: If you have a garbage disposal system in your sink, you need a better-quality sink that can take the vibrations it will generate.

Gauge chart

Look at our stainless steel gauge chart that will tell you the exact thickness you can expect. Gauge isn’t the same for all types of metals. For instance, a 14 gauge in steel is equivalent to 0.0751inches while a 14 gauge carbon sheet has 0.747 inches of thickness.

Let’s look at the thickness you will likely encounter in kitchen sinks.

16 gauge

16 gauge stainless steel is considered a luxury buy in the sink market. It is because it is one of the thickest and highest quality materials there is. It has a thickness of 0.0595″ and is usually employed in high-end commercial spaces or luxurious homes.

Although it can make a great basin, it also works well as a heavy-duty worktable. Worktables of this gauge can be used in bakeries, professional kitchens, and more.

18 gauge

With a thickness of around 1.27mm or 0.0480″, 18 gauge steel is a premium option for use around the house. It’s resistant to corrosion and rust, thus a great option for use around water-prone areas like the sink and garage.

You can also make worktables, pipes, almirahs, and storage units out of this sheet. It can also be used for panel installation, crafts, and other decorative uses around the house and offices.

Things to look for

There are other things to consider apart from just the thickness of the metal when it comes to kitchen basins. Here are a few to consider.


A deep and large sink might be tempting because of its large capacity to hold many utensils at once. But there’s a catch. A deeper drop-in kitchen sink also means more crouching your back. You have to be careful with under-mount sinks because they will be a whole inch lower than what they measure in depth.

Kraus sink

Six inches deep sinks are too small and splashy, but 9-10inches make perfect sense for home kitchens. Keep a mental note not to have too much depth in under-mounted kitchens.

If you’ve got too much depth and want to adjust this, you can get a basin rack for the inside.


Are there grooves inside for smooth drainage of the water? Are the corners straight or soft-angled? While soft angles make for easy cleaning, the straighter angles give more volume overall.


Is the drain located in the center or the rear? Center drains are fine when you’re washing. When piling dishes in the sink, the drain can get clogged quickly. It causes water to overflow. A drain to the rear left or right then makes for quick water draining even with piled stacks of dishes.


Knowing the thickness isn’t enough, the grade must also be of premium quality. 18/8 is the desired combination of about 18% chromium and 8% nickel. It is also known as the 300 series.

Good stainless steel will not stick to magnets, and that’s how you will know whether what you have is sound or not.

If you want to go deeper into the knowledge of gauges, take a look here.


Under mounting with rubber pads might sound like something a sink might or might not need. However, it’s more essential than you think. If you’re the kind to do dishes at night when everyone has slept, you don’t want to wake up the whole house with the clatter.

Underproofing pads provide the much-needed soundproofing on the sink to avoid this. It will reduce the noise of the running water and silverware and crockery.


While it is the best choice, other materials apart from stainless steel can be employed to make a kitchen basin. These are :

  • Enameled cast iron: a unique choice but has its advantages too. It is very durable and hard-water resistant. There is little competition when it comes to denting and chipping. It’s even antimicrobial. But scratches! The scratches are plenty, and they might be a deal breaker for you if you pay attention to aesthetics. It’s also super heavy. Get ready to install heavy-duty countertops.
  • Enameled steel: It’s a steel frame with a coating of enamel that is non-porous. It’s durable like enameled cast iron but a little cheaper and with a few differences. It also offers almost the same advantages, except it could chip and dent if you push it.
  • Fireclay: This is exactly as it sounds. Made in the proofing of high temperatures to form a tough material, this is not only resistant to stains, scratches, and rust. However, it is prone to cracking when heavy or sharp objects are dropped. It’s recommended to keep the base protected with a plastic grid.

What is the best option?

16 gauge stainless steel sink

It is recommended to have 18 gauge or 16 gauge stainless steel basins. If you are weary of the price range, you can also go for 20 or 23. But you must consider that these will be lighter, will induce more noise, and will only be able to take on a limited weight of dishes.

Anything higher than 23 is simply a no-go. 16 is the best number for kitchen sink gauges and is the most used gauge in commercial spaces.

Mistakes to avoid when buying

There are some big-time mistakes to avoid whenever you go kitchen sink shopping. Here they are for your benefit!

  • Never go thrift shopping – Did you happen to find a ‘vintage’ sink in an old junk shop or online and think it will give a great traditional or gothic vibe? Resist the urge to buy. Not only will it be hell to find compatible faucets and fittings, but the pipes will always exit and enter awkwardly. You will require custom cabinetry and probably spend way more than you thought you were saving by buying a thrift shop sink.
  • Not considering size – Is your sink too small or too big for your counter? Measure it out and plan the details. You don’t want to have a tiny sink that can’t hold much and piles up with dishes faster. But you also don’t want limited counter space with an oversized sink looming.
  • Not considering faucets: Wide faucets will be a mess with shallow sinks as they will splash everywhere. Power-spray fittings and small sinks are a big no-no. You want the faucet to match the sink size and depth. Otherwise, you will likely have either a splash pool or an odd-looking tiny tap in an oversized pool of a sink.
  • Deep kitchen sinks: If you are tempted to buy a kitchen sink with a large depth so it can store more, don’t act so fast. A deeper one can break hell on your back with all the crouching. It is good for taller people, but those with average height should measure before buying.
