Best Undermount Kitchen Sinks In 2021: Ideal Tips for Buyers

A house is only a home because of its kitchen. So much happens there; the essence of home is contained inside the kitchen.

Thus, it only makes sense that the most important appliance in the kitchen adds value to your experience.

Yes, I’m talking about the sink!

All that lead-up just for a sink, and why? Because think about it. Could you cook, clean, or do anything important without the sink? No.

Now, functionality is key when it comes to choosing the right kitchen sink. And that’s why, today, I’m going to tell you about the best undermount kitchen sinks, and why you should consider them.

So, keep reading to see what it’s all about!

Why Get an Undermount Sink?

I now owe it to you to explain why undermount kitchen sinks are worth your consideration.

So, what are they?

Well, as the name suggests, an undermount sink will be mounted underneath your kitchen counter, as opposed to above it. They are fixed in place with the help of adhesive and brackets, or clips.

Compare this to drop-in sinks, which are “dropped in” to a cutout in the countertop. The sink’s lip, therefore, juts out onto the counter, which translates to some hassle in the long run: difficult to clean and clumsy in appearance.

However, in the case of undermount sinks, a lot of these problems are eliminated. Being mounted under your counter means that the sink’s rim will be concealed, giving your kitchen a much cleaner, sleeker, and clutter-free appearance.

More importantly, they’re much easier to clean. This is because, as I have said, there is no space between the sink’s edge and the countertop. This means food and debris won’t be able to get stuck there.

Undermount sinks are especially worth a try if you’re renovating your kitchen or building a new one. That’s because, in comparison to drop-in sinks, they tend to be designed for more high-end kitchens, so they are of higher quality.

5 Best Undermount Sink Reviews

So, without further ado, here’s my list of the five best undermount sinks on the market right now. Of course, your options aren’t limited to this list, but these are definitely a good place to start.

Thus, give each one a thorough read to find the perfect one for you, or simply to get an idea of what the best sinks look like.

1. Kraus Standart KHU103-33 Stainless Steel Kitchen Sink

Kraus Standart KHU103-33 Stainless Steel Kitchen Sink

This double bowl sink is probably the right one for you if you have a bigger kitchen. You probably have a lot going on in there every day—if you like to cook with a lot of ingredients or with several pots and pans, then a double bowl sink can be a huge help.

This one, in particular, is quite versatile owing to its 60/40 configuration. That means that one of the bowls is just a little bit smaller, which makes it perfect for multi-tasking. So, you have one main bowl where you do your main tasks, and a smaller side bowl for various purposes.

So, let’s look at some specs. The outer sink measures at 32 3/4” L x 19” W x 10” D, with the mini cabinet size at 36”. And what’s it made of?

Yep, stainless steel, which is the choice of most sensible homeowners. The manufacturers have chosen, for this sink, T304 16-gauge stainless steel. That results in a sink that is not only super strong but will last you for many years to come. It’s specifically built to resist corrosion and rust.

But probably the real kicker in regard to this product is the soundproofing technology the manufacturers have built into it. They have supplied it with their NoiseDefend technology, which basically manifests in a non-toxic undercoating with thick pads that cover a large portion of the sink.

A quieter kitchen is a more functional kitchen if you ask me. This sink also has a bottom that slopes gently downwards, preventing any water from staying inside the bowl. The angle has been optimized so that any upright glassware won’t collapse inside the sink.

Pros

  • Purchase includes free accessories like dish grids and a basket strainer set
  • Soundproofing technology will ensure a quieter kitchen environment
  • Ideal for bigger kitchen
  • Rust and corrosion resistant

Cons

  • Removable basket is likely to rust if not maintained regularly
  • Is likely to get scratched easily.

2. Kraus Standart KHU102-33 Stainless Steel Kitchen Sink

Kraus Standart KHU102-33 Stainless Steel Kitchen Sink

You may already know this brand because they’re a favorite with customers everywhere. I personally really like this brand because, despite their relatively high affordability, their designs offer both durability and aesthetic value.

The reason these sinks can last so long is that they’re constructed using T304 stainless steel, which is extra strong and offers superior resistance to rust and corrosion. The TRU16 construction also makes the sinks resistant to dents.

This model, in particular, comes with soft round corners which have the ability to augment your workspace. As I said earlier, these sinks are great for aesthetic value; they look quite smart and sleek, and will usually fit into most types of kitchens, no matter what the rest of it looks like.

Oh, did I mention that this is a double-bowl model? That’s right; if you have a bigger kitchen that you spend a good amount of time in, you’re probably looking for a double bowl sink. This one has a 50/50 configuration, which is perfect for daily multitasking in the kitchen.

Drainage is obviously a big concern with sinks, and the manufacturers of this one have kept that in mind. These sinks have a subtly sloping bottom that works against water accumulating inside the bowl. You also don’t have to worry about accidentally breaking any dishes or glassware that you leave inside the bowl.

Like lots of other sinks from this brand, this one also comes imbued with their soundproofing technology. The sound-absorbing pads are extra thick, spreading over about 80% of the base of the sink and offering greater insulation.

So, if you wanna say bye-bye to the annoying noises of waste disposal and washing dishes, this sink can help!

Pros

  • Supremely easy to clean due to rounded edges
  • Double bowl sizes improve functionality
  • Depth prevents water spraying
  • Affordable price tag

Cons

  • Likely to scratch easily
  • Not fully compatible with a garbage disposal

3. ZUHNE Modena Stainless Steel Kitchen Sink

ZUHNE Modena Stainless Steel Kitchen Sink

So, this one is special, because it is strong. I kid you not. If you’re someone who spends a good amount of time in the kitchen and is prone to going on all sorts of culinary adventures, then you need a good, strong sink.

Furthermore, if it’s a priority for you to find a sink that fits well into your granite or composite countertop, then you also need a good, strong sink. For either or both of those situations, this sink is probably it for you.

Why is that? Well, it’s made from surgical grade stainless steel; namely, 16G T304 18/10 Posco. Of course, it’s resistant to rust, corrosion, dents and scratches, and all those good things.

But this sink was built to be able to compete with industrial strength construction, which makes it the ultimate contender for durability. The manufacturers even claim that it can even be used for commercial use!

The sink itself is a single bowl one, measuring at 32 inches. The sloped base channels ensure faster draining and drying, which saves you a lot of time. The 3.5” drain set in the rear gives you lots of free sink area and cabinet space. You’ll be able to store large items with ease.

The bowl in this sink is significantly wide and deep, so you have a ton of space for your dishes. And of course, there’s a much lower chance of spraying from faucets.

Something else I love about this sink is its noise-canceling ability. This sink will basically shut up your incinerator and save you from the annoyances of daily kitchen working sounds.

What’s even better is that your purchase will also include a bottom grid, sponge holder, caddy, colander and strainer, and grate protector. What a win, all around.

Pros

  • Well-functioning grid
  • Rubber coating has a sound-dampening effect
  • Constructed using heavier gauge steel compared to other brands
  • Super easy to clean—just use a damp rag

Cons

  • The drain is made from plastic; not too durable
  • Drain ring not fully compatible with the garbage disposal

4. Kraus KBU24 Stainless Steel Kitchen Sink

Kraus KBU24 Stainless Steel Kitchen Sink

Yes, the next sink on the list is another double bowl, for the multi-tasking chef that you are. This one has a 60/40 configuration, which as we know, is almost a must for a busy kitchen where you will be performing a large number and variety of tasks every day.

What’s great is that when you’re ordering this product, you can request that they put in the smaller bowl on either side. That means extra flexibility and compatibility with your unique kitchen needs.

Adding to this is the fact that the smaller bowl is just a little bit higher up than, the larger one, which can greatly augment your overall working experience in the kitchen. Stack your dishes on one side and store your vegetables in the other or mix and match.

Another great plus point for this sink is its very classic look. You can rest assured that it will fit into both contemporary and traditional kitchens. So, whatever your new kitchen is going to look like, you can’t go wrong with this one.

This sink is constructed with high-quality premium T-304 stainless steel. And there’s really very little room for error with stainless steel if you ask me. Especially considering its non-porous surface, you can expect this sink to resist corrosion for many years to come.

And that’s not all, of course. This guy comes with an undercoating of a stone guard. This, coupled with the thick rubber pads built into the sink, help to insulate sound and increase your overall kitchen experience. No one wants to hear the incinerator do its dirty work, am I right?

Pros

  • Soundproofing technology cancels out unwanted kitchen noise
  • Dimension variation in bowls creates a more versatile workspace
  • Comes with additional accessories of great quality
  • Looks great

Cons

  • Water spots might appear on the stainless-steel surface

5. Blanco 511-702 Diamond Equal Double Bowl Kitchen Sink

Blanco 511-702 Diamond Equal Double Bowl Kitchen Sink

I’ll be finishing off today with a beautiful double-bowl granite composite sink, because honestly, the best sinks have two bowls, and are made of 80% granite. (If you don’t agree, you’re not thinking straight.)

Right off the bat, though, you should know that this sink is not the cheapest option out there. So, if you’re on a budget, I’d suggest skipping this review, because it will definitely make you jealous. Because despite what you may have heard, the best things aren’t free.

But boy, are you gonna love forking over the amount for this one. What I especially love about it, as I may have already mentioned once (heh), is its construction. It is made from 80% granite composite, which is perfect as it provides the highest durability.

Despite how strong this guy is, though, it’s actually quite light. That means easy and quick installation, without any additional worries about the strain on the countertop. It’ll fit breezily into your 36” cabinet and leave over lots of space for you to store other necessary items and tools.

I also love that this sink comes with its own stopper, soap dispenser, and waste strainer. Yes, most other sinks from reputable brands also come with extra accessories, but you’d be hard pressed to find one that will offer such high-quality ones.

So, if you are not operating on a tight budget and want a beautiful undermount sink that not only looks great but also gives consistently good results, definitely consider this one!

Pros

  • Beautiful anthracite finish will make your kitchen look sleek and elegant
  • Highly durable due to its 80% granite construction
  • 50/50 bowl is a great choice for multitasking
  • Lightweight

Cons

  • Does not include a drain
  • Low affordability

Buying Guide: What to Look for in a Touchless Kitchen Faucet

So now that you’ve gone through my picks of the top undermount sinks on the market, you must be thinking more seriously about purchasing one.

Before you do, though, there are a few things to consider. You have quite a number of options, even beyond this review. Plus, a sink is a pretty permanent fixture; you want to know you’re getting the right one for your kitchen.

So, here’s what you need to know.

Price

Yes, the most important bit. How much will an undermount sink cost you?

As with everything else you can buy with money, the price will obviously depend on quality and style. And because those vary so much, the range is quite large.

The cheapest undermount sinks will cost you anywhere between $75 and $100, while the most expensive ones will burn up to a $1000-sized hole in your wallet.

I can see your face going pale from here. Not to worry! The majority of reliable undermount sinks fall into the range of $200 (for stainless steel ones) to $500 (for materials like cast iron). That’s far more affordable.

Drain strainers and faucets will also have to be bought separately. In total, those will also set you back up to $200.

Keep in mind that having it installed will probably add up to $200 to your total expenditure on an undermount sink—it’s tedious work! More on that later.

Countertop Considerations

This is something you need to decide before you start thinking about putting in an undermount sink.

Undermount sinks do not go well with tile or laminate counters; this is because they are weaker along joints and seams. As a result, they will be incapable of supporting the sink’s weight.

When it comes to undermount sinks, countertops with solid surfaces are ideal. So, what kind of material should you choose?

Your best options are stone, wood, or composite, although they are not your only options. I would suggest matching your budget for your countertop material choice.

Sink Material

What do you want your sink to be made of? The options in this category are pretty much endless. Here’s a rundown of your options, along with pricing estimates.

Obviously, the most popular choice is stainless steel, because it’s durable and strong. Stainless steel sinks come in many different thicknesses, but ultimately, that’s relatively unimportant. Depending on size, you can expect these to cost up to $800.

Porcelain enamel is another favorite because they are affordable and can also complement nearly any kitchen’s aesthetic value (they come in a variety of colors!). These guys will cost anywhere between $300 and $900. Be warned, however, that porcelain might crack if heavy objects come into contact with it.

Next, are composite sinks. They are constructed by mixing materials such as granite and quartz. They’re a popular choice for those on a budget as they usually don’t cost more than $400. However, they require much sturdier counter surfaces.

Finally, if you have the privilege of a bigger budget, definitely consider soapstone or granite. Not only are they super durable, but they’re also the best looking! In fact, they will do the best job of matching your counters. Expect these to set you back up to $1000.

Amount of Bowls

As you probably already know, kitchen sinks can come in either single- or double-bowl designs, and sometimes more. The first thing you’ll have to decide which kind you want to buy. In some cases, a single bowl may not be well suited to your kitchen style.

It goes without saying that a single bowl is your best option if your kitchen is smaller, even if you think you’ll need the extra space.

Two bowls will definitely look better in a larger kitchen, giving it a little bit more character.

Installation

As we have already established, your countertops should have a solid surface if you’re looking to get an undermount sink installed.

They require quite a bit of structural support. This support must come from within the counter. In the absence of mechanical support, the adhesive holding your sink in place is likely to give out.

Then you’ll have quite the messy situation on your hands when your sink is at the bottom of your counter!

There are several ways to support an undermount sink. Professionals will likely suggest sink harnesses or custom wooden braces.

Something else to remember is that faucet, and hardware holes have to be drilled separately for undermount sinks. They usually aren’t designed with these holes, so those holes have to go into your countertop.

So, what does all this mean for you? Well, it’s unlikely that you have either the skills or the tools required to install an undermount sink. Even though it will definitely cost you extra (as I have said before), professional installation is very, very important.

Dispensers

This part is totally optional but can add that little pizzazz to your undermount sink set-up.

Many people like adding undermount dispensers (for things such as dishwashing material, hand soap, or lotion) to complement their sink. Of course, it’s an ingenious method of de-cluttering the counter workspace.

But it will also greatly increase functionality and make for a more seamless kitchen experience.

So, if you have a little extra to spend, you can definitely look into installing dispensers. They come in a variety of finishes and styles and will do wonders for your kitchen space.

Frequently Asked Questions

What is the difference between undermount sinks and other types of sinks?

The main defining characteristic of an undermount is that it goes under your counter as opposed to it. This has several benefits, which are elaborated above.

What kind of undermount sink should I buy?

You have several options when it comes to material, starting from stainless steel to porcelain enamel, all the way up to composite and granite. It mostly depends on your budget.

The prices can vary greatly, with the cheapest ones being around $100, and the most high-end ones coming to about $1000. The price will depend on a variety of factors.

You most likely will not. In fact, you should consider getting a professional to do it, even though it will cost you quite a bit.

Final Words

As with any home fixture, however, it’s important to find the right fit to avoid unexpected surprises in the future. In my personal opinion, you should go for the best undermount sink even if it costs you a little extra.

A kitchen sink is, after all, a very necessary part of everyday life.

So, choose wisely, and I wish you good luck!
