#1 The Winner
This is a commercial grade single bowl undermount kitchen sink. It is large enough to handle even the largest pots and pans and is super insulated for minimal noise. It is made out of stainless steel which is a top choice for food prep areas because it is very easy to clean and is a durable metal. It is resistant to spots, fingerprints, and scratches.

The only downside of a stainless steel kitchen sink of this size is noise from dishes and water.

Undermount Kitchen Sink Buying Guide
Undermount kitchen sinks are popular in both commercial and home kitchen settings for a variety of reasons. They are aesthetically pleasing as well as having many practical benefits. Here are a few of the ways a high quality undermount kitchen sink can improve your kitchen experience.
Advantages of an Undermount Kitchen Sink
One of the top reasons why people decide to go with an undermount kitchen sink for their home is because of its modern, seamless appearance. Undermount sinks sit below to counter, with no lip or raised edge that interrupts the flow of the counter. This makes the lines in your kitchen clean and crisp for an aesthetically pleasing, contemporary, and modern feel.
- Seamless appearance.
- Can be classic or contemporary.
- Sits below the counter 100%.
The outer rim of a kitchen sink can become a breeding ground for mildew, mold, and germs. The clean, sleek lines of an undermount sink makes it easier to clean because there are no crevices where dirt can hide.
- Less crevices for dirt to build up.
- Better appearance.
- More hygienic.
More Counter Space
The outer lip takes up about two or three inches at least on an average drop-in kitchen sink, and with a new undermount kitchen sink you'll be saving that space. It may not seem like a big difference, but those couple of inches of space can be utilized for storing a soap dispenser, water filter, or more.
- Utilize every inch of your counter.
- More room to cook.
- More room to clean.
Things to Consider in an Undermount Kitchen Sink
So you’ve decided that an undermount kitchen sink is right for you. What’s next?
There are lots of undermount kitchen sinks on the market in a variety of styles, shapes, finishes, and each with their own unique features. To decide which one is right for you, there are a variety of things to consider.
We've put together this handy list to help you determine what features and functions are most essential to you.
The size of your kitchen sink is very important. You will want to make sure your sink is big enough to handle all of your kitchen needs including cleaning and cooking. You'll also need to make sure that the sink is small enough to fit your kitchen cabinet properly. Here’s how to know:
- Is It Big Enough to Handle Pots and Pans?
Think about the biggest pot or pan that you own. Will it fit in this sink? If not, then move on. You will need a sink that is big enough to handle all of your kitchen cleaning tasks, so don’t cut corners on size just to save a few bucks.
If you don’t use any large pots or pans, you maybe can consider a small model of undermount kitchen sink, but for most homes ample space is required to efficiently clean pots and pans and one of the best things about undermount kitchen sinks is their ability to make the most of a space.
- Does It Fit Your Kitchen Cabinet?
This point is an absolute must. Unless you plan on going through a messy, expensive remodeling process, you will want to be sure that the sink you choose fits with your existing kitchen cabinet. A large sink will require a large cabinet and vise versa. You may be able to edit an existing cabinet for a larger sink, but it is not recommended as it may compromise the integrity of the structure. Measure your sink multiple times for accuracy while taking measurements.
When talking about stainless steel undermount kitchen sinks, the gauge thickness refers to the thickness of the metal used in construction of the sink. To understand what the gauge number represents you need to know that the lower the number, the higher the thickness. So a thinner sink would be 22-23 gauge, and a higher quality sink would be 18 to 19 gauge.
Gauge is important for several reasons:
- The gauge, or thickness, of the metal determines how strong it is.
- Thinner metal is louder.
- Thinner metal is damaged easier.
- For a long-lasting sink choose a thicker gauge.
Different materials have different resistances to heat. Metal is highly conductive and can easily heat up when exposed to hot water. A kitchen sink with a higher heat resistance is preferable because not only can hot metal or porcelain cause burns, but a lack of resistance to extreme temperatures can make the sink more susceptible to damage. Extreme cold or heat can crack, melt, or bend the sink.
When the sink heats and cools, it can cause condensation to build on and under the sink. This condensation and moisture can be the cause of all sorts of damage. Moisture can corrode through materials, even high-quality ones, and cause health-threatening mold and mildew. The moisture can also freeze over during cold months causing damage to the structure of the sink and the piping.
When dishes and other objects hit the side of the sink it can make obnoxious clanging noises especially with certain kinds of metal. Using a different kind of material can help to soften the noise and there are also several noise reduction features available. These techniques can even extend the lifetime of the sink because they prevent condensation from building due to temperature changes which can cause damage and corrosion over time.
Rubber padding on the sink base can help create a soundproof barrier to absorb the noise of an impact. The padding may also extend to the sides of the sink as well to prevent noise from water splashing up. This type of sound insulation is great for larger undermount sinks, whose large walls can create more of an echo.
There are also certain kinds of coatings that can be applied to the sink base and sides to help dampen the noise. These spray on coatings help to neutralize the vibrations which cause noise. A spray-on coating is less effective than other methods, reducing but not eliminating noise. It can be combined with padding and other techniques.
Classic vs. Farmhouse Style Kitchen Sink
All undermount sinks are designed to be installed underneath the counter, instead of dropped in on top. Traditional undermount sinks are made to seamlessly integrate with the counter, and not be seen. A farmhouse kitchen sink, on the other hand, is still undermounted, but it becomes the focal point of the kitchen because the front of it shows through.
A ceramic farmhouse kitchen sink can add a touch of traditional style to a kitchen, whereas a stainless or brushed steel front can create a more industrial look. Since farmhouse sinks take up more space than smaller stainless steel models, you'll need a reasonably sized kitchen to show one off effectively.
The material used is the number one indicator of how much noise the sink naturally makes, but any material can be sound-proofed with the correct additions.
Denser materials such as porcelain or quartz are much more effective at absorbing noise than thin metal materials. A higher gauge, or thickness, of metal will also be more effective at reducing noise.
Granite is a material made out of combined resin and stone for a classic marbled appearance. Granite has become a less popular material for sinks in recent years as consumers and manufacturers have shifted towards cheaper and faster methods, but granite is one of the most durable and long-lasting materials for a sink construction.
Granite has a stylish, luxurious, and classic appearance. It has a far more unique look than a metal or porcelain sink. It has the look of a stone sink, but is more affordable. Undermount sinks can be made out of pure granite or a combination of granite and quartz/other components.
- Reasonably priced.
- Looks like natural stone.
- Available in different colors.
- Can be made out of the same material as counter for seamless appearance.
- Resistant to heat and damage.
- Heavy material that may require assistance with installation.
- If not sealed properly it can chip or stain.
- Sealing needs to be reapplied annually to maintain.
Stainless steel is often the best kitchen choice for surfaces in both food prep and health care environments because it is one of the most hygienic metals. It is also very resistant to fingerprints, spotting, and damage. Stainless steel is a durable, heavy metal that is much stronger than lighter metals. The lower the number of gauge, the thicker the metal and the more durable construction.
For modern homes, a stainless steel kitchen sink is a top choice. It is very affordable and there are stainless steel sinks of all shapes and sizes. The finish of a stainless steel kitchen sink can be polished for a reflective, mirror-like appearance or brushed for a soft matte, homier look.
- Strong metal.
- Can be polished or brushed for different looks.
- Metallic, gray appearance.
- Easy to clean.
- Low maintenance.
- Resistant to chipping/cracking.
- Easy installation.
- Can scratch.
- Can be noisy.
- Limited colors.
Quartz, like granite, is another unique choice for kitchen sinks that stands out from the traditional stainless steel and chrome. Quartz sinks are made out of a composite of resin and quartz stone, for one of the most durable and long-lasting sink materials. Quartz composite undermount sinks have the look of real stone, but with a lower price.
- Resistant to heat.
- Very sturdy.
- Easy to clean.
- Naturally soundproof and noise-resistant.
- Appearance is long-lasting.
- Affordable and beautiful.
- Can integrate seamlessly with the counter.
- Lower maintenance than granite.
- Can cause accidental breakage if you drop a dish.
- Limited finishes.
You may also hear porcelain described as vitreous china or ceramic. Porcelain sinks are beautiful and durable, and give a traditional look to any kitchen. They have a beautiful smooth white appearance and can come in other colors as well. It holds up well over time, and can be combined with other materials for an even more durable construction.
- Easy to clean.
- Variety of colors and designs.
- Temperature resistant.
- Reduces noises.
- Can chip.
- Abrasive cleaners can damage surface.
- Can stain.
Single vs. Double Bowl Kitchen Sink
Undermount sinks come in both single and double-bowl varieties. They each have benefits and disadvantages, and are both great options for different households.
A single bowl kitchen sink is basically smaller, so great for smaller spaces, and leaves you with more counter space for other kitchen tasks. It's less expensive and has just one drain hole, which makes for easy installation. The main drawback of a single bowl kitchen sink is that with just one bowl your sink can often be full of dirty dishes, making it difficult to wash greens or use it for other tasks.
A double bowl kitchen sink takes up more space, but gives you more flexibility: you can use each bowl for a different task (washing and rinsing, or washing and prepping), or two people can use the sink at the same time. Depending on the design, the two bowls can be the same size, or one bowl can be smaller than the other.
The downsides of a double bowl kitchen sink reflect the advantages of a single bowl: a double bowl has two drains, so is more difficult to install, and double bowls are usually more expensive.
As you can see, there's no such thing as the one best kitchen sink model: your choice of one bowl or two really depends on space and how you plan to use your kitchen sink. If you're really stuck when deciding, look out for so-called low divide kitchen sinks, which have a lower divider and are able to function as either single or double bowl depending on the water level.
As with anything in life, the cheapest isn’t always the best. On the flip side, the best undermount kitchen sinks aren't always the most expensive either, although price usually does indicate quality.
The price of the sink largely depends on the material. Real stone, granite, and quartz sinks are pricier than stainless steel, but a stainless steel kitchen sink is easier to maintain.
In addition to the materials, the price may reflect whether or not installation is included (as well as mounting hardware), delivery costs, and warranties.
Most reputable companies include a free factory warranty with the purchase of their products.
A factory warranty is a guarantee from the manufacturer that they will cover the costs of any sort of product defects, and replace the product if necessary. The warranty will often all include the finish and any shipping damages. Many of the products reviewed in this guide come with a limited lifetime warranty from the manufacturer which guarantees excellent performance of the product for the lifetime of the kitchen.
You should always contact the customer service department of the manufacturer when buying your sink to find out more about your warranty options. Reputable manufacturers will have a friendly and highly trained team of customer service representatives available to answer questions, at least during regular office hours.
How to Measure for Installation
Using a high-quality and accurate tape measurer you should determine the measurements of the cabinet where you plan on installing the sink. You need to measure the length and width of the space as well as the depth. If the sink is too big for the cabinet, it may be altered, but it’s not recommended as this can compromise the structure of the cabinet and could make the cabinet’s warranty void. Most sink manufacturers will share the recommended cabinet size in the product listings and descriptions.

|Kraus KHU100-30||Single Bowl||Undermount||30" x18" x 10"||10"||9|
