Kitchen sinks are necessary for every kitchen. They provide a place to wash dishes among a variety of activities like meal prep. Undermount sink types have become increasingly popular due to their contemporary look, and easy installation. The best undermount kitchen sinks are worth an investment if it means you get functionality, practicality, and easier cleanup. If the name didn't already cue you in, here is a breakdown, of what an undermount sink is.

The first sink on our list Kraus KHU100-32 Standard Undermount Sink which has a cutting-edge design, and easy-clean corners which offer more space for washing dishes. The second sink is the KRAUS KBU32 Premier 32-inch 16 Gauge Undermount which is bowl style sink that features a seamless transition, but has sharp corners making it harder to clean. Lastly, the DELTA 95B932-32S-SS Lorelai workstation sink, which is dent-proof, and has a sleek modern look.

What is an Undermount Sink?

An undermount kitchen sink is a sink like any other, save for the way it's mounted onto a countertop. Rather than being installed into a pre-cut hole, an undermount sink is positioned under the sink. This type of installation ensures there is a seamless transition between the sink and the countertop. There are no unsightly edges or rims visible making it very practical since rims tend to catch debris. Undermount sinks are loved and renowned for their aesthetics and how they complement solid surfaces and stone countertops.

Whether an undermount sink is best for your kitchen largely depends on your preference, budget, and the type of counter you have. Here are some of the best undermount kitchen sinks in the market, depending on their quality, materials, finishes, shapes, and sizes.

Kraus makes some of the best sinks and faucets in the market, so it's not a surprise that their undermount sinks take the cake. This Kraus stainless steel sink has a commercial-grade brushed finish which means it's resistant to rust and corrosion. It's also conveniently paired with a matching faucet for the ultimate Kraus experience.

Its cutting-edge design features non-toxic undercoating for superior protection against noise. This comes in quite handy since my other sink had a very noisy operation with the drainage. This kitchen sink on the other hand has superior drainage with a gently sloped bottom that allows water to run off the surface. Furthermore, the easy-clean corners are rounded to increase the surface area for washing dishes and prevent food and debris from getting stuck in any corners.

This sink comes in a variety of sizes, so you won't have to cut out parts of your counter to make your sink fit. You simply have to choose one that fits. Furthermore, the sink comes with mounting hardware, a cut-out template, installation, and care instructions. I should point out that you can choose to DIY the installation or have a professional install it, since some plumbing will need to be rearranged, depending on the drain opening.

Pros:

  • Rust and corrosion resistant
  • Easy to clean
  • Fairly easy to install
  • Heavy-duty
  • Deep and wide to accommodate

Cons:

  • The rack will leave scratch marks on the sink

If you prefer the double bowl sink style, this Kraus is a great option. The double bowl sink features durable TRU16 real 16-gauge stainless steel with a satin finish that won't dull. Not to mention, it's a heavy-duty sink that won't dent which means it's very tough. Furthermore, this workstation sink has an undermount installation which makes it easier to wipe water and crumbs straight into the sink, since it has a seamless transition into your countertops when installed well.

A feature that stood out to me is the low divider which is not common in double bowl sinks. The rounded corners provide extra clearance which makes it easier to separate clean and dirty dishes so you can preserve counter space. Additionally, this double basic sink is fully insulated with extra-thick pads to absorb noise and vibration so there aren't any echoes when I turn on the high-pressure faucet.

The bottom of the sink is engineered for easier drainage since it has an optimized slope that promotes runoff. The sink features a double bowl sink, stainless steel bottom grid, a drain assembly, mounting hardware, and a cutout template.

Pros:

  • Durable
  • Lasts long
  • Easy to clean
  • High quality for a great price
  • Great customer service

Cons:

  • The bottom racks are flimsy

The kit includes a durable cutting board and roll-up dish rack with a removable utensil holder that allows you to combine prepping and cleaning in one convenient location. Furthermore, like any deep sink, it is made with 16 gauge stainless steel which is dent-proof and offers lasting durability so that you can use your sink with confidence.

The Noisedefend Soundproofing technology ensures the Delta undermount sink greatly reduces noise and vibrations around your sink and countertop. It also provides generous space for washing your largest cookware and stacks of dishes while containing the mess. Additionally, the anti-condensation coating makes it harder for water to damage any of my cabinetry or counters.

If you'd like a modern sink with a low profile for a small kitchen, then this is an excellent fit. The drainage grooves ensure water pools on the drain for easier discharge, and the large radius corners make it easier to clean. Additionally, the sink creates a clean modern look that feels at home with all the décor in my kitchen.

Pros:

  • Easy to clean
  • Spacious
  • Heavy-duty construction
  • Functionality-boosting accessories

Cons:

  • Minor craftsmanship issues

Equipped with a single-tier rack, and other accessories, this stainless steel kitchen sink is built to maximize the functionality of your kitchen. Of course, with a commercial-grade brushed finish, the sink hides scratches. Additionally, since it's a heavy-duty 16 gauge sink, it will never rust or dent whether you wash heavy pots.

Image Source: rtakitchenandbath.com

The rinse grids protect the sink from scratches and act as a drying rack for my pots and pans before storage. Additionally, the strainer basket helps to trap food that might be leftover or stuck at the bottom of my crockery. Keep in mind that the strainer only applies to standard plumbing. If you install a garbage disposal, you don't need it.

The deep bowl prevents any water from ruining your countertops, not to mention you can pile copious amounts of dishes without them being unsightly or visible. Additionally, while the sleek 90-degree edges give the sink bowl a great look, it makes it harder to clean since I have to hose it down after use.

Pros:

  • Scratch resistant
  • Durable construction
  • Large basin style
  • Long-lasting construction

Cons:

  • Hard to clean

5) Hykolity 26-inch Undermount Kitchen Sink

For a single bowl sink, this highly polished stainless steel is an affordable option if you're in the market for one. It's made of commercial-grade stainless steel for a robust, dent-free, and efficient workstation. Additionally, the 16 gauge stainless steel with 1.5mm thickness is durable and long-lasting while still offering a sleek and contemporary look.

Image Source: ubuy.com

The gently sloped bottom and rear-set drain are engineered for complete drainage, and the optimized angle still keeps glassware from falling. Additionally, the sound-deadening feature comes with 80% improved insulation, so the noise is not deafening when I turn on the waste disposal. Like most under mount stainless steel sinks, it is deep enough to accommodate a busy kitchen.

The corners of this drop-in sink give about half-an-inch allowance for easier cleaning. If you're in the middle of a kitchen remodel, I would suggest you start with this affordable but durable and functional workstation sink.

Pros:

  • Easy to clean
  • Easy to install
  • Resistant to scratches
  • Durable
  • Large

Cons:

  • Get's water spots

If you're worried about your sink drain opening fitting your existing standard garbage disposal unit, then this is a great solution. Its incredibly durable stainless steel construction with under-mount installation guarantees more counter space and durability. The deep bowl will easily accommodate large cookware and bakeware without denting.

The basin is undercoated and padded to reduce running water noise and any cabinet condensation you might experience. Additionally, an anti-condensation spray on the undercoating to prevent moisture accumulation. Additionally, the matching drain ensures water isn't retained on the bottom of the sink, and the grid prevents scratches as you wash your dishes. The added drain strainer basket ensures all the food particles are caught.

While the bottom of the sink is flat and doesn't pool water, the drainage is slower and leaves debris that I have to chase with a hose down the drain hole. Therefore it would help if there was a slight dip in the bottom to help with this.

Pros:

  • Durable construction
  • Accessories included to guarantee functionality
  • Scratch resistant
  • Large and deep

Cons:

  • Hard to clean

If you prefer superior drain quality over other features, then this is the sink your kitchen desperately needs, including a drain for garbage disposal. Like any other under-mount sink, the workstation is equipped with an impressive modern design, even if you have limited counter space. Even installation is a breeze if you know how to go about a DIY.

The drainer included in this kit consists of stainless rods inserted in a rubber stripping that fits smoothly along the lip of the sink, allowing one to wash dishes and rinse them while utilizing the drainer at the same time. It was also very helpful when it came to preventing scratches on the bottom of my sink. Furthermore, it cuts down food preparation time by providing a place to defrost food and clean vegetables.

Lastly, the soundproofing feature is a great addition since the outer parts are well-padded and work exceptionally well since I can hardly hear water trickling down the drainage. Furthermore, it's large and accommodating, so it can hold a large amount of dishes.

Pros:

  • Convenient for washing many dishes
  • Installation is easy
  • Durable
  • Great customer care

Cons:

  • The angle to drain the water isn't steep enough

Some people prefer the look that farmhouse sinks add to their kitchens, and this sink offers it without the added costs that come with the purchase, installation, and maintenance. Naturally, it is constructed with heavy-duty 18 gauge stainless steel, which ensures there aren't any dents or scratches and guarantees a long service life.

Image Source: thehomedepot.com

The back of this 33-inch stainless steel undermount kitchen sink features an anti-condensation coating that prevents damage to my cabinetry from condensation. The noise reduction features a 3mm thick noise-reducing rubber mat that muffles the sounds from the sinks operation. It works well for me since the garbage disposal noise is now a muffled hum.

For easier water drainage, the sink has an X-shaped bottom which ensures efficiency when cleaning the sink. The sink was very well-packaged and arrived without a hitch or an unsightly dent. It's also well-made and will last long.

Pros:

  • Looks great in any kitchen
  • Durable
  • Easy to clean
  • Creates a great workstation
  • Well-made

Cons:

  • Slow drainage

This Ecochannels undermount sink is an excellent addition to any kitchen with a strong countertop. It also has an integrated ledge as a track for sliding the built-in custom accessories. The track also allows you to work directly over the sink with ease. If you're working with heavy pots, the high-density stainless steel with a brushed finish prevents the sink from denting or retaining water spots.

As a single basin sink, it also boasts high temperature-proofing, scratch-resistance, and rust-resistance, meaning it will never rust or stain. Most sinks I've had have the drain assembly in the center. However, this sink has a rear drainage hole design to increase the space for washing dishes. Additionally, drain grooves in the sinkhole help to drain water quickly and prevent water from pooling.

The sink has a standard fitting for normal drains, and it will fit in most kitchens, even small ones. Of course, it wouldn't be an undermount sink without rubber insulation against sound, so you won't be able to hear any sounds.

Pros:

  • Well-made accessories
  • Efficient water drainage
  • Easy installation
  • Great for small kitchens and households
  • Looks great

Cons:

  • The utensil grid might rust

To offer more counter space, this undermount sink is excellent if you prefer the functionality of a workstation. Not to mention, this excellent quality sink has multiple ways of installation, which makes it versatile if you're remodeling and don't know which sink to pick. Remember, it's a large capacity sink, so you can easily wash your largest cookware in it.

Image Source: pinterest.com

Multi-functional dish grid protects the bottom of the sink from scratches and also allows you to wash and rinse at the same time. It's also deep enough to prevent any splashback on me or my counters. However, it has 90-degree angles for corners, which might limit cleaning. However, with this type of sink, I find a spray down works well to remove any trapped food particles.

Lastly, the sloped base works well to prevent water from pooling, and the anti-condensation layer prevents any water damage to the surrounding countertops.

Pros:

  • Easy to install
  • Heavy duty construction
  • Large
  • Efficient drainage

Cons:

  • Scratches easily

Factors to Consider Before Buying and Installing an Undermount Sink

Any kitchen sink has to stand up to daily activities. There are many different types of sinks, and here are some of the things you have to consider before buying and installing an undermount sink.

a) Durability of Material

Most undermount sinks are made from stainless steel, copper, granite composite, porcelain, and cast iron. The material used to make a sink is critical to determine its durability and how long it will last. Each material has its advantages and disadvantages. A stainless steel sink is durable and very easy to maintain since it doesn’t require much in the way of upkeep. Other materials, such as cast iron, will stand the test of time even in the busiest kitchens.

Durability of Material

Durability is key when replacing your old sink. Since sinks are always exposed to water, rust is the main threat. Stainless steel is rust-resistant but not immune to rust and can be corroded by chemicals and heat. So before subjecting your stainless steel sink to any of these conditions, ensure it’s pre-treated for rust and heat.

b) Size

The size of the kitchen sink you choose matters. You need a sink that’s large enough to fit on your counter but not so large that it takes up too much counter space. Additionally, this is the time when you consider a single, double, or triple bowl kitchen sink, depending on the size of your kitchen and your needs.

Size

Image Source: homedepot.com

As you consider the size, also consider the measurements of where your sink is supposed to fit. For undermount sinks, measuring where the edge meets the counter will give you a good idea of the size. Additionally, a deeper bowl will offer more functionality, but shallower bowls are easier to install. It’s also a good idea to keep in mind that the larger the sink, the heavier it is.

c) Sound-proofing

If noise control is important to you, then you’re better off selecting a sink that has soundproofing. The sound-deadening material aids in absorbing and dampening vibrations brought on by running water or the impact of dishes and utensils on the sink’s surface, which can lessen the noise. Stainless steel sinks are popular but notorious for noise.

Sound-proofing

Sound-proofing steel sinks are important to increase their comfort, usefulness, and aesthetic appeal. However, soundproofing doesn’t have anything to do with functionality. Therefore, you might not want to get it, or you might prefer the sound of water running through your plumbing.

d) Accessories

Accessories

Modern kitchen sinks come with multiple new accessories to increase their functionality. A few extra touches can increase the sink’s usefulness and cleanliness. This automatically makes cooking easier and cleaning afterward a bit less of a headache. Accessories such as dish racks will allow clean dishes to dry without touching the sink but roll up when not in use. Also, built-in cutting boards are a handy touch, as are produce trays and colanders.

Frequently Asked Questions About the Best Undermount Sinks

i) Are undermount kitchen sinks better?

Yes. Undermount sinks make cleaning easy. They are a perfect choice to keep the home clean. Because they are caulked or clipped directly to the vanity or counter space, there is no gap underneath the sink, making them perfect for any household.

ii) What to look for when buying an undermount sink?

Weight: Stainless steel or copper sinks tend to be the lightest, while vitreous china, porcelain, ceramic, and composites are moderately heavy. Choose a heavy stone, cast iron, or enameled-steel undermount sink only if you’re sure the countertop can support the weight.

iii) Why choose an undermount sink?

Undermount sinks are a popular choice for many homeowners because they offer a sleek, seamless look that is easy to keep clean. Because there is no lip around the edge of the sink, it is easier to wipe debris directly into the sink rather than having to clean around the rim of the sink.

The Bottom Line

If you’ve tried to wash dishes in a shallow sink, you know how frustrating it can be. Every kitchen requires the right tools to be functional, including a great sink. Picking the right sink should be a primary concern in the first stages of the kitchen design process. The right undermount sink will not only last long, but its functionality will make a great workstation.
