Next, we have a buying guide where we’ll discuss in-depth information of undermount kitchen sinks and answer some of the most frequently asked questions. Let’s take a look at 10 of the best undermount kitchen sinks for granite countertops!
The Kraus Standart PRO KHU100-32 has a sterling reputation as one of the best undermount kitchen sinks for granite countertops on the market and is our Editor’s Choice. This Kraus model is noted for its amazing craftsmanship with this elegantly yet simplistically designed single bowl sink.
It is made of fine stainless steel and comes in the usual grey steel color that is enhanced with a nice satin finish giving it a great and smooth feel. The stainless steel material is corrosion and rust-resistant and, thus, is very easy to clean. We think the size of this sink is absolutely perfect for normal to bigger-sized granite countertops as it is large enough to house all of your dishes, but, at the same time, not that big to take a lot of kitchen space. It has a width of 32 inches and a depth of 10 inches, which is deep enough, so you’re not splashing water everywhere too.
This fantastic sink also comes with a few great accessories, including a dish grid, a 3-piece basket strainer set, and mounting hardware to help you install this sink on your own. Although this sink is very popular, some owners have noted that it tends to scratch a bit easier, but this is common among stainless steel material sinks.
The Ruvati RVM4250 sink is another great choice for granite countertop in your kitchen. This sink is our Best Value pick, and for under $200, you get excellent quality with this model that is comparable to many other products on this list.
This single bowl sink comes in a wide range of different sizes, but the one we’ve focused on is the 30 x 18 x 9 inches sink. At 30 inches wide and 9 inches deep, this sink is large enough for most granite countertops. It has rounded corners, so you’ll have to cut this particular shape. This shape helps to add a stylish look to your countertop and kitchen. It is made of stainless steel material, and like the Kraus PRO, it also has a smooth satin finish as well. Despite being a very budget sink, it still has a lifetime limited warranty on it in case you need it to be replaced if it arrives damaged.
This sink earns its Best Value nomination thanks to the few extra additions such as a bottom rinse grid, a basket strainer, and mounting brackets and an installation guide for easy, do-it-yourself installation. A few people did note that on top of the scratches that can easily appear with this sink, it can also show rust spots after a few months, which you’ll have to find a way to clean off. Despite this, this sink is still a tremendous and undeniable value.
The first granite composite-made kitchen sink on our list is our Premium Pick, the BLANCO PERFORMA CASCADE Super Single Bowl. This beautiful single-bowl cascaded sink comes in a smooth grey color but is also available in a number of other fantastic colors to add an excellent touch to your kitchen and complement your granite countertop.
As we mentioned, this sink is unique thanks to its cascaded design, which simply means that this sink is divided into two levels, with the larger part of the sink being lower. This slightly raised part of the sink is great to put fragile items that are prone to rolling around in the sink and getting caught in the drain. The granite composite will easily match and go well with your granite countertop because of its sheer quality. This sink is heat, scratch, and stain-resistant, which makes it very easy to maintain and clean. As for its size, it is absolutely perfect for a single-bowl sink and is not too long nor too shallow either. At 32 inches wide and 10 inches deep, this sink has standard dimensions, so it should fit any kitchen.
The product has an exceptional curved design around the edges to it as well that adds another layer of style to this already very stylish undermount sink. People that own this sink rave of its excellent quality and durability. One small note they did make is that this sink can have a buildup of calcification from treated water, but a little bit of scrubbing can easily make this go away.
Another Ruvati kitchen sink that appears on our list for the top 10 undermount kitchen sinks for granite countertops is the Ruvati RVH7300. Like the previous model by the same manufacturer, this Ruvati sink is made of stainless steel material, but this one has a brushed finish instead of satin.
This sink is made of 16-gauge premium grade stainless steel that ensures it is rust and stain-resistant. This Ruvati comes equipped with SoundGUARD padding and noise-proof undercoating that helps to minimize the noises and sounds from the sink. This Ruvati sink also comes in a variety of sizes, but we prefer the standard size of 30 x 18 x 10. It is wide enough for most granite countertops and deep enough to keep plenty of dishes in there too. You’ll only need a minimum of 33 inches of a base cabinet size to install this sink. It comes with a stainless steel rinse grid that can help to protect the bottom of the sink from scratches and can also be a great place to dry your dishes and pots. One note that people make about this sink is that it can be pretty deep to reach into the sink for dishes, especially for shorter people, and can be hard on the back doing these dishes.

The first sink made of quartz to join our top 10 list is the Elkay Quartz Classic ELGU2522. Quartz material is more durable, solid, and it is harder than granite. However, it can have less heat resistance than granite. This single-bowl sink has a very slick dusk gray color (a combination of black and grey), but it is also available in a variety of darker and lighter tones, so you don’t have just one option with this product.
The quartz material of this sink has a very smooth matte finish that should match nicely any kitchen. This sink is actually much smaller in width than other models at just under 25 inches, so if you have a much smaller granite countertop, this Elkay sink would be the perfect addition to it. Its smaller size also means you need less cabinet size space to be able to fit this sink (30 inches), which can be a huge advantage if you have limited space. On the other hand, it can fit fewer dishes per load. Still, people who own this sink love it for its easy to clean and stain-resistant qualities. It makes cleaning and maintaining process an absolute breeze, and that is all thanks to the quartz material.
Another really solid choice for an undermount kitchen sink for your granite countertop is the Mensarjor Undermount Single Bowl Kitchen Sink. This Mensarjor is made of 18-gauge premium grade stainless steel and has a brushed finish. This means that this sink is extremely sturdy and will be durable enough to last you a long time.
It has quite standard dimensions of 27 x 18 x 9, which is a very good size to have on medium-to-large granite countertops. This single-bowl sink is very minimalistic in design as it comes in a rectangular shape and has the drain right in the middle of the sink. A small yet quite fantastic feature of this sink is that the bottom of the sink is slightly tilted, and this helps to prevent the water from standing still. It means that it will always flow into the drain hole. A few owners have commented, however, that despite this feature, water can sometimes have difficulty going through the drain, leaving you with a buildup of water in the sink.
On the other hand, you can find more value with this sink because of its Thickening Noise Reduction Coating, which helps to keep the sound down by absorbing it from the source. Lastly, this sink comes with a bevy of extra add-ons, including a 3-piece basket strainer for waste, a dish drying rack, and three soft sponges for cleaning.
The smallest undermount kitchen sink on our list is the HOUZER CS-1307-1. It is going to be an ideal solution for your granite countertop in the kitchen if your space is quite limited, or you just want to have a larger cooking area.
With just 12 inches wide and 6 inches deep, you’re not really looking to fill this sink up with dishes. Despite its compact size, this sink is made of 18-gauge stainless steel, so you know it’s a high-quality product that should last you for decades. Its surface is hygienic and scratch-resistant, so it doesn’t need much maintenance. Moreover, a silencer pad helps to reduce noise when the water is running.
It has a nice satin finish and rounded edges and comes with mounting clips and a template to help you install it. Doing so is a really simple task that should take minimum time. It requires much less cabinet space, only 18 inches, and it will provide a nice touch to any granite countertop. You’ll be glad to know that there is a limited lifetime warranty so consumers can purchase this sink with confidence, knowing that their money is safe.
Perhaps one of the sleekest-looking undermount kitchen sinks for granite countertops is the Kraus Forteza KGD-54BLACK. This sink is made of premium grade granite composite materials that is naturally hygienic, meaning that the material is enriched with ions that help to fight off the germs to make it much clearer.
This model is highly resistant to heat (up to 650 degrees Fahrenheit). In terms of the size, it measures out to 33 x 22 x 9.6, making it one of the largest sinks in our list. At 33 inches wide and 9.6 inches deep, that is more than enough room for your pots and dishes to fit. When the water is running, you’ll be happy to know that this sink is very quiet thanks to the thick, stone-like material that helps to eliminate the vibration and sound.
Lastly, this sink is also very convenient for homeowners because it gives you the option of either installing it undermount or drop-in and comes with mounting hardware. Since it is a bigger sink, you’ll need at least 36 inches of cabinet space to be able to install it safely. If there is one common complaint among owners of this sink, it’s that the sink’s corners were damaged or cracked upon arrival. So, be sure to inspect this Kraus sink carefully when you receive it.
Why is it special?
Made of premium granite composite material that is hygienic
BLANCO makes another appearance on our list of the best undermount kitchen sinks for granite countertops, this time with their BLANCO DIAMOND 1-3/4 Bowl. We’re calling this model our Best Double Bowl Sink because of its fair size and beautiful granite composite design. It comes in seven distinct and unique colors that all have their own ways of complementing the granite countertop and kitchen aesthetics.
Since it is a double sink, it is a tad bit wider than normal single bowl sinks and measures out to 33 x 22 x 9.5 inches. The left side of the double bowl is slightly bigger than the right one and also has a small curved accent at the top to give it a bit of flair. BLANCO has a reputation for making high-quality sinks and that’s what you’ll get with this double bowl sink too. The sink is incredibly durable thanks to the patented material BLANCO used to produce this heat, scratch, stain, and chip/impact-resistant surface.
Like the Kraus Forteza sink, this BLANCO sink is also 100% hygienic and protects you from germs in foods. It gives you the option of installing it as a drop-in or undermount sink as well. One of the downsides of this sink, however, is that many people complained that the product arrived broken when it was shipped to their house. Just be extra mindful of inspecting it on arrival and contact customer service right away, if you do notice anything wrong.
The last fantastic kitchen sink here is the Swanstone KS03322DB.018. As the title suggests, this double bowl sink comes in an array of colors. These spotted patterns provide a wealth of character to the sink and add a nice flair to your granite countertop too.
This double bowl sink has the exact same dimensions as the double bowl BLANCO sink at 33 x 22 x 9. Like the BLANCO, this Swanstone sink has the bigger bowl on the left and the smaller one on the right. The left one also has a curved accent to give it even more charm and character. It is made of granite composite material, and the sink itself comes with a pre-drilled faucet hole, which is great as it will save you some work and time.
Nevertheless, the sink does not come with a faucet or a drain. Still, this Swanstone sink is heat, stain, and scratch-resistant. However, the heat-resistance only goes up to 450 degrees, which is quite a bit lower compared to other granite composite sinks. Despite being stain-resistant, a number of owners have commented that this sink can stain rather easily, but it really depends on the type of food that goes in this sink and how long it sits there for.

Things to Consider
After taking you through the 10 best undermount kitchen sinks for granite countertops, it’s now time to turn our attention to some of the details. With so many products around, it can be hard to make the right choice. This section is designed to educate you further about many of the things you need to consider when it comes to purchasing an undermount sink. If you still have questions, stick with us, and we’ll hopefully be able to answer them here. Let’s get started!
How to pick Undermount Kitchen Sink?
With 10 different undermount kitchen sinks for granite countertops to choose from, no one would blame you if you had a hard time deciding which one to buy. Thankfully, we’re here to help you! In this section, we’ll go through the most important things you should consider when it comes to purchasing a kitchen sink. Here, we will discuss the dimensions, bowl type, materials, color, mounting hardware, accessories, and warranty. All of these factors are essential, so it can be a wise idea to make some notes as you go through this section.
When it comes to the dimensions of the undermount kitchen sinks, you can choose from a few different options depending on how much space you have on your countertop. From single, double, and even triple sinks (more uncommon), you can choose a model depending on your needs. A safe estimate for an undermount kitchen sink is anywhere from 20-50 inches of space. With this amount of space, you should easily be able to fit an undermount kitchen sink.
One thing you will need to be mindful of is that you have sufficient space beneath the undermount sink to be able to install it properly. Installing an undermount sink is significantly more difficult than a drop-in sink, so make sure you have measured everything correctly.
If you are looking for a variety of sizes, check the Ruvati RVH7300, and you will be able to find the perfect model right for your countertop.
The bowl of the kitchen sink can come in various shapes and sizes. Some of the most common ones are your traditional rectangle or square bowl, while others have curved or rounded corners. Also, depending on the sink you buy, there can also be more than one bowl as some undermount sinks can have multiple bowls.
Many people may prefer a single bowl sink, but we’re starting to see that double bowl models, just like the BLANCO DIAMOND 1-3/4 Bowl, are quite popular too. Double bowls are ideal because they have multiple purposes. For those cook, you can separate your food preparation in one bowl while keeping your dirty dishes in the other bowl. You can also separate your garbage disposal (garburator) by keeping it in one section. The only downside to the double bowl is that it takes up more space and can actually hinder your ability to clean much larger dishes.
When it comes to the most common materials used in undermount kitchen sinks, two particular materials are kings: stainless steel and granite composite.
Stainless steel is perhaps the most common material used in undermount kitchen sinks and for a good reason. A stainless steel kitchen sink is relatively light, so it is going to be easy to install. Moreover, it will undoubtedly look good in any kitchen environment you have. It’s easy to clean it, and it is corrosive-resistant as well. The Kraus Standart PRO KHU100-32 is a perfect example of a quality product here.
Granite composite is another popular material for kitchen sinks, and it is known for its scratch, heat and stain-resistant qualities, making it tremendously easy to wash. It can look good in just about any type of kitchen. This is the case with our premium pick, the BLANCO PERFORMA CASCADE Super Single Bowl.
Thanks to the sturdiness, granite composite sink is long-lasting and has an ability to maintain a cleaner look even after years of use.
Fortunately, undermount kitchen sinks can come in a wide variety of colors, but it really depends on the type of material you use for your sink. For undermount kitchen sinks made of stainless steel, you’re just going to get the classic grey stainless steel color with satin or brushed finishes. For models made of granite composite, like the Swanstone KS03322DB.018, you can get an array of unique colors including arctic granite, bermuda sand, bisque, black galaxy, bone, gray granite, tahiti desert, tahiti ivory, tahiti sand, tahiti white, white. For sinks made of quartz, such as the Elkay Quartz Classic ELGU2522, you’re looking at bisque, black, dusk gray, greige, greystone, mocha, pecan, putty, sand, and white. Having different colored sinks can add a lot of character to your granite countertop and to your kitchen as well. But, if you’re a purist, you might just want to settle for the traditional grey colored sink from stainless steel.
Mounting hardware and accessories
You’ll have to really read the full product description of the undermount kitchen sink you’re interested in because not all of them come with mounting hardware or accessories. However, among the ones that do, some of the most common accessories you may find include a rinse grid (stainless steel is preferable), a basket strainer, and even special towels. The rinse grid is important because it can separate the bottom of your sink from your dishes so that your dishes aren’t swimming around in leftover food. You can also dry your dishes and pots on the grid as well. Some kitchen sinks also come with their own mounting hardware, and this usually entails a cutout template and mounting brackets. These items come with an installation guide, so it should be fairly easy to install the sink.
Having a kitchen sink with a warranty is crucial because you’re just never sure what can go wrong with them. Fortunately, all of the models on this list come with lifetime limited warranty. Therefore, the manufacturers show their confidence in the products, and your money is safe. If you receive a damaged sink with cracks or if you find that some of the accessories are missing, you can rest assured that these issues will be solved very fast.
We strongly urge you to read the terms of the warranty before purchasing your kitchen sink as they can differ by the company and even by the product.
What else should I look for?
Some of the undermount kitchen sinks also come with special features. The most common one is extra padding that helps to reduce the noises and sounds made in the sink. It really depends on the sink you’re looking at, and this padding can be different for each sink. Another feature that is a nice-to-have is a pre-drilled faucet hole. We found this with the Kraus Forteza KGD-54BLACK and the Swanstone KS03322DB.018, to name a few. It is very convenient since you won’t have to cut out the hole by yourself manually.
The prices of undermount kitchen sinks can vary tremendously depending on the material of the sink and the size of it as well.
The cheapest sink in our list is also the smallest one in size, and it is the HOUZER CS-1307-1 at $87. The most expensive one on our list is our Premium Pick, the BLANCO PERFORMA CASCADE Super Single Bowl. It comes in at a whopping $530 because of its beautiful granite composite material and its convenient size with a fantastic depth of 10 inches.
In between these two, you’ll find the rest of the undermount kitchen sinks. They are priced reasonably close together, within the $175-225 range. If you are looking for a high-quality undermount kitchen sink in this price range, it’s hard to look past the Kraus Standart PRO KHU100-32. This sink is made of stainless steel and comes with a bunch of useful accessories.
Undermount kitchen sinks are a perfect addition to any kitchen. They really let the granite countertop stand out even more. Since the sink’s rim is hidden under the countertop, this allows you to have more space on your counter. They also come in a wide variety of colors, sizes and shapes, and this is great because it will complement the look of your kitchen and the overall design aesthetics. Lastly, and maybe the best part is that having your sink under the countertop means you’ll be able to easily wipe the food or crumbs from your countertop straight into the sink without it getting caught on the rim of a non-undermount sink.
To measure your sink base cabinet, all you really need is a tape measurer. First, you’ll want to measure the total depth of your cabinet, including the frame. You’ll want to measure front-to-back, and you simply place your tape measure on the bottom of the cabinet and place the other end of the tape against the back of the cabinet. Next, you’ll want to measure the width, and you do this by measuring the bottom of the cabinet and measure going from left to right. Lastly, you’ll want to measure the height, and to do this, you take the tape measure that’s still on the bottom, and you measure this going straight up to the top of your cabinet. After that, you can check the sink description to make sure it fits your cabinet. If it’s not specified, you can subtract three inches from the width of the cabinet and one inch from the depth to calculate the right size.
Undermount kitchen sinks are very sturdy and much cleaner than on-top sinks for granite countertops. This is proven to be true by the fact that all of the kitchen sinks we reviewed have some sort of limited lifetime warranty, and this just goes to show that these companies stand and believe in their product. These sinks are scratch and heat-resistant (up to a certain temperature for each sink), and most are impact-resistant. While you’ll still want to be gentle anyways, it’s good knowing that pots can clang around without repercussion. Some, but not all, undermount kitchen sinks also have non-stick surfaces, and this just helps to maintain the cleanliness of the sink easier. So really, undermount kitchen sinks for granite countertops are a fantastic choice thanks to their durability.
Okay, it’s time to unveil our top three undermount kitchen sinks for granite countertops.
