Features to Consider When Selecting Your Stainless Steel Undermount Kitchen Sink

Type of Stainless Steel

No matter if you require a stainless steel sink for industrial use, commercial or kitchen use, know that there are two types of stainless steel used: T-201 and T-304. Stainless steel sinks are a blend of Chromium and Nickel. It's the Chromium which provides your sink with its shine and durability, whereas the Nickel adds the strength. Of the two, T-201 is the weaker steel, and should be avoided. T-304 is the stronger of the two, and should be the only type you choose for your sink.

■ T-201 Stainless Steel

T-201 stainless steel is made with 16 to 18 percent chromium and 3.5 to 5.5 percent nickel. The T-201 stainless steel sink is not as durable as its counterpart and can scratch and pit easily. Even your basic kitchen cleansers can do damage to it over a prolonged period of time. Avoid any sinks that come with this grade of steel if you're searching for quality and longevity in a sink.

■ T-304 Stainless Steel

T-304 stainless steel is where it's at when looking for stainless steel sink that offers strength, beauty and longevity. Here, both the chromium and nickel have a higher percentage, with chromium taking up 18 to 20 percent and nickel 8 to 11 percent. This makes your sink much more durable. This stainless steel is scratch, rust and stain resistant as well.

Thickness or Gauge

Many people make the mistake of thinking that the higher the number the thicker the steel, but such is not the case. When looking at the specs, know that it is the lowest number which represents the thickest steel. For instance, 16 gauge is much thicker than 18 gauge. Thicker gauge steel will be able to resist dents much easier than thinner gauge.

■ 16 gauge

16 is the thickest gauge sink available on the market today. 16 gauge sinks come with more than adequate sound deadening and with an excellent finish. All of the stainless steel sinks in our review of the best stainless steel undermount sinks are of this gauge.

■ 18 gauge

The 18 gauge stainless steel sink is the one you'll generally see in the average home and commercial kitchens. Sound deadening is good, and the finish is adequate for its use. This sink has no trouble dealing with heavy cook pots but is not as durable in the long run.

■ 20 gauge

One of the first things you'll notice with a 20 gauge stainless steel sink, is the course, rough finish. Purchasing a sink at this gauge might be cheap, but you risk pitting, scratching and denting during your daily sink chores. If you have a garbage disposal, expect noise and vibration.

■ 23 gauge

The 23 gauge is the thinnest gauge offered for stainless steel sinks. These are among the cheapest sinks, so don't expect too much of a smooth, shiny finish. This sink is often referred to as the "Builders Special". They are referred to as the builders special because they are the cheapest for the builder to purchase and install. However, they will dent, scratch and make quite a bit of noise, especially if connected to a garbage disposal

Undercoat

Let's face it, no one wishes to hear a bunch of cook pots and utensils clanging against a stainless steel sink. This brings us to sound-dampening undercoating. However, not all undercoatings are the same. Look for an undercoating that has been applied in a thick layer to the entire bottom of the sink. A word to the wise, different stainless steel sink companies may have their range of undercoating, so check with your chosen seller for details.

The Correct Depth and the Thump Challenge

The size of the sink, depends on your countertop. Avoid sinks with a 6-inch depth. They may be cheaper, but you won't get much use out of them, and the splashing can become a messy annoyance over time. Instead, look at a bowl depth of between 9 to 12 inches. While you're testing out the depth of the sink, it might not hurt to give it the Thump Test. Here, you'll give the bowel a nice thump, and wait for the sound. If it sounds tinny or clings like a metal drum, then it won't have the soundproofing that you need or want.

Installation

For you do-it-yourselfers, you'll find that it's the top-mount, stainless steel sink that is the easiest to install. However, if you want to preserve as much countertop as possible, then go for an undermount, which might be a bit harder to install, but will give you a return of more space on your countertop. In our review of the best stainless steel sinks, we've chosen the undermount as it maximizes both countertop space and makes it easier to keep the countertop clean from debris, as you just push it into the sink.

Never allow any type of cast iron cookware has prolonged contact with the stainless steel surface.

Keep any soaps which contain bleach from getting in contact with the stainless steel sink, as chlorine causes pitting.

Frequently Asked Questions

Q1. Will an stainless steel undermount kitchen sink rust or dent?

Ans: When you see what looks to be rust on the bottom of high quality, stainless steel sink, you're looking at a brown stain on the surface, not actual corrosion. These stains can come about in a variety of ways. First, don't use a steel wool pad to scrub the sink, and definitely don't let it sit on the bottom of a wet sink, as you will get a brown stain. Second, it can't be stated enough that in some areas the iron content in the water if left to sit on the bottom of the sink, will also cause a discoloration. But these on only discolorations, not corrosions. As for damage? This depends on what you do to it, and the gauge of the sink. Sinks with a lower gauge, such as 16 or 18 probably will never dent, but one with 23 gauge thickness can run the risk of dents occurring.

Q2. Why do I have to rinse and wipe my sink down after use, it seems a waste of time

Ans: The water from your faucet may look pristine and clear, but that's far from reality. Depending on your location, or whether or not you use a water softener, your water will contain minerals and salts. it's when this tap water evaporates that unsightly spotting occurs. If you take a soft cloth or sponge and dry your sink, you won't see the minerals. Some homeowners find that using a splash of white vinegar before wiping down helps and also adds to the shine.

Q3. I'm thinking of getting an undermount stainless steel sink, but my friend told me granite or porcelain is better, which should I choose?

Ans: This depends on your needs. Both composite granite and porcelain sinks gorgeous to be sure, but when compared with stainless steel, they are often more expensive, heavier, and can crack and chip over time. Whereas an undermount stainless steel sink is cost effective, lightweight, durable, easy to maintain, won't crack or chip, and can last a lifetime.

Q4. My friend has some ugly stains at the bottom of her stainless steel sink, what are they?

Ans: With the proper care and maintenance, stains should not appear on your stainless steel sink. However, over time accidents can happen. Other members of the household may decide to scour it with a stainless steel pad, which can result in a stain, or perhaps some people let food and debris just sit in the sink without bothering to clean it. More than likely though, these stains are due to the minerals and salts in your water, which is why it's crucial to wipe your sink down after each use.
