Best Undermount Bathroom Sinks

Here is the list of the 11 best undermount bathroom sinks to help you find the perfect sink for your bathroom.

1. KRAUS KEU-12WHITE Undermount Sink – Best for Noiseless Cleaning

This Kraus sink has bagged one of the top spots on this list, thanks to its elegance, durability, and functionality. Kraus gives you all of this and more. Installed with a proprietary Noise Defend technology, you won’t have to worry about annoying sounds of dishwashing or waste disposal. Keep reading to know all the deets about this product.

The minute we set our eyes on this undermount sink, we just knew that it would make it to the list! If the aesthetics of this product isn’t enough to sway you, the specifics indeed are!

Believe it or not, the first thing you will notice about this sink is just how lightweight it is. Although it looks like a cast iron sink, the stainless-steel core is what makes the difference. This core makes the sink 65% lighter than its cast iron counterparts which most people like.

Furthermore, the fascinating quality of this sink is its Noise Defend technology. Yes, it’s exactly what it sounds like! With extra-thick rubber padding and a protective foil layer, this sink is unbelievably quiet.

Why is that helpful? Well, you don’t need to worry about those disturbing sounds your sink usually makes when you run the garbage disposal.

Due to its super shiny finish, scratch marks are more visible on this product than on its non-shiny alternatives. Another thing is that the brand name (KRAUS) is boldly printed on the sink. This isn’t really a problem, as you could always turn the sink around so that the name is on the inner side.

2. KOHLER K-20000-0 Caxton Undermount Sink – Best for Customization Options

If you were already impressed with the last two products, then here is another one you should check before making up your mind! American Standard Studio Carre Undercounter Sink comes in a square design that looks sleek and compact. With a measurement of 13 by 13 inches, it can be the perfect addition to your neat and organized bathroom.

When it comes to durability, resilience, and strength, this product is similar to the previous ones we reviewed. However, its unique selling point lies in its compact, neat, and square appearance.

The mere size makes this sink an excellent product for those looking for an undermount installation without the fuss and worry of size and fittings. Measuring just 13 by 13 inches, this unit gives you enough room to decorate the rest of your vanity with other items!

Besides, the customizable overflow position of this undermount sink is another excellent personalization factor that made this product one of our favorites. This sink also comes with a template and mounting kit, making it all the more comfortable for you to have a hassle-free installation process.

For those looking specifically for a compact undermount sink, this might be your best bet. However, keep in mind that the smaller size also means a shallow basin and more splash. We think that this is the only factor that could have been better, and would have added to the overall functionality of the undermount sink.

4. Nantucket Sinks Undermount Bathroom Sink – Best for Small Vanities

Even though the Nantucket undermount sink is also made of vitreous china material, there is one feature that sets it apart from the previous products – the beautiful porcelain enamel glaze.

With a sleek, rectangular design, the Nantucket Sinks Undermount Bathroom sink is the perfect fit for your bathroom vanity. And its pure white color just adds to its elegance.

We have already talked greatly about the last three products, so now you’re left wondering what this undermount sink’s unique factor is. Well, the biggest USP of this product is its superb fit and size.

If you have a smaller vanity in your bathroom or are just looking for something rectangular that doesn’t take up too much space, then this is the perfect product for you.

Of course, the vitreous china gives this sink that added durability, which you cannot find with most other materials. The shiny glazed finish adds appeal to your undermount sink, making it a statement piece.

If you have a 21-inch cabinet base, you might have heard that the only undermount sink that will fit your vanity is a customizable one. Well, Nantucket Sinks has created this perfect fit just for bathrooms like yours!

What Could’ve Been Better?

Although you are provided with a template for cutting the holes in the sink, they aren’t always a perfect fit. Unfortunately, this could lead to issues if you plan on using the templates for cutting the holes in the sinks without checking. We recommend that you individually check the template and compare it before cutting the holes.

5. Kraus KCV-121 White Rectangular Ceramic Bathroom Sink – Best for Modern Bathrooms

One of the best features of the Kraus KCV-121 Undermount Bathroom Sink is how sturdy and substantial it feels in your bathroom. If you are looking for a modern addition to your home, then this is a great fit. Moreover, the shiny finish enhances the appeal of this undermount sink.

What we liked the most about the Kraus KCV-121 were its modern looks. The smooth, rectangular finish and soft curves of the undermount sink perfectly fit into your modern home. The bright white color, along with its glossy finish, gives it a premium feel.

Besides its aesthetics, this sink has useful functionality. The sink’s height is neither too deep nor too shallow – measuring 4.18″ on the inside. We especially like this feature since it ensures that water splashback is significantly reduced.

Although the sink has an undermount design, it is super versatile, fitting into your creative bathroom ideas. You can choose to install the sink above the counter, as well as semi-recessed. Moreover, the undermount sink is super easy to install – you can even do it yourself!

Unlike other bathroom sinks, the ‘Kraus’ logo on this model is not too bold or large. Even though the logo is quite subtle, many people would not like the logo to be seen at all. Thankfully, there is a simple enough fix to this – you can simply choose to install the sink with the logo facing inward!

6. Kingsman Undermount Bathroom Sink

Are you looking for a classic rectangle undermount sink, which is a timeless beauty? If yes, then the Kingsman Undermount Bathroom Sink is a great option. The simple yet versatile design of this undermount sink adds depth and value to your powder room.

Kingsman Undermount Bathroom Sink comes with a standard 1.75-inch drain opening. It works beautifully with both a pull-up as well as a pop-up drain with overflow.

In terms of looks, the undermount sink is pure white, dipped in elegance and style. Furthermore, the neat design of the unit blends in perfectly, complementing your existing decor and fixtures. The vitreous ceramic make of the Kingsman adds to its durability and strength, along with its style.

Apart from being highly durable, the undermount sink is super easy to install and clean. The polished surface of the unit allows you to clean it with minimal effort. Moreover, the modern yet versatile design of the sink allows seamless integration into your bathroom space.

If you are wondering about installation, Kingsman Undermount Bathroom Sink has made it super simple. You have all the necessary mounting hardware included to be able to make this a simple DIY project.

Honestly, we didn’t find any significant downsides to this undermount sink from Kingsman. However, these sinks do not come with drains, so you will have to purchase a pop-up or pull-up drain, based on your preference and requirement.

Color: ‎‎‎‎White | Shape: Rectangular | Material: Ceramic | Dimensions: ‎15.25″D x 21.5″W x 8″H | Drain Type:‎ Pop-Up

7. Kohler K-2355-0 Archer Undermount Bathroom Sink

Do you prefer clean-cut, geometric designs that add a modern finish to your vanity? The Kohler K-2355-0 Archer gives you just that in terms of looks and appeal. Of course, there’s much more to this unit than just its good looks – don’t forget durability and versatility too!

When it came down to a clean, cut design with geometric features, the Kohler K-2355-0 Archer Undermount Bathroom Sink turned out to be one of our favorites. The combination of a curved base, rectangular design, and beveled edges gives a modern yet elegant appeal to this unit.

An interesting choice of the strategically placed overflow hole ensures that the beauty and charm of your undermount sink are not compromised. Furthermore, there is no faucet or faucet hole, which gives the unit a clean appearance. You can buy a faucet kit of your choice, which will complement the rest of your bathroom decor.

We were impressed by the vitreous china material used for this sink, which added to its strength and durability. However, weighing in at 21.2 pounds, the sink is quite heavy and does not resemble other flimsily made, lighter sinks.

Apart from that, the sink is generous in its size and will add a luxurious and majestic look to whichever bathroom you install it in.

Although the geometric design and shape of the undermount sink are exceptional, the unit does get dirty more quickly than an oval or round one. With regular cleaning, this shouldn’t be an issue at all. However, the dirt tends to accumulate at the edges, making them harder to clean sometimes.

8. Nantucket Sinks UM-13×10-W Undermount Bathroom Sink

An oval sink design has an appeal of its own – it is clean, compact, and fits in easily with its surroundings. The Nantucket Sinks UM-12x 10-W Undermount Bathroom Sink is the perfect oval sink for compact spaces. Crafted from vitreous china, the sink is sturdy, durable, and long-lasting.

When we think of a compact undermount sink design, we look for something classy, clean-cut, and functional. The Nantucket Sinks UM-12x 10-W fits the bill, making it an excellent choice for your compact bathroom space.

Now, although this undermount sink is petite, at just 13″ x 10″, the curvature of the bowl is deep enough to eliminate unnecessary splashback. Apart from that, the unit also comes with an overflow, ensuring water spillage is kept to a minimum.

The best part about the design is that the overflow is placed at the front of the undermount sink, so you don’t even have to look at it – but it does its job efficiently.

We also liked the quality of materials used for this undermount sink. The use of vitreous china gives it unmatched durability. Along with that, the porcelain enamel glaze enhances the aesthetics by adding shine and gloss to its appearance.

There is not much to say in terms of negatives for this undermount sink. Although there is an overflow present, there is bound to be some splashback or spillage in this petite undermount sink – if there is increased water pressure. However, this is easy to avoid if you can adjust the water pressure in your faucet.

Color: ‎‎‎‎White | Shape: Oval | Material: ‎Vitreous China | Dimensions: ‎‎‎12″D x 15″W x 7.5″H | Drain Type:‎ ‎‎Pop-Up

9. Wells Sinkware Undermount Bathroom Sink

Although pure white sinks have an appeal of their own, the Wells Sinkware Undermount Bathroom sink is a stunning ebony unit that looks sleek and unique in any bathroom space.

The gentle slope of the sink ensures water flows smoothly without accumulating and creating a mess. Moreover, the glossy finish adds class to the overall appeal.

To be fair, the first thing that caught our eye in the Wells Sinkware undermount bathroom sink was the stunning ebony color and its sleek design. Even though the sides of the sink slope down gently, the back is still flat, adding to its modern look and appeal. The unit is 7 inches deep (interior), which is a perfect fit for most modern bathrooms.

Another useful feature of this undermount sink is the material – vitreous ceramic. Not only does this add a glossy, shiny finish to the sink, making it look quite majestic, but it also adds considerable strength. The polished surface also allows you to clean it easily. However, you should be careful not to use very abrasive cleaners on its surface.

Lastly, we liked the fact that this undermount sink comes with an overflow. Additionally, the overflow hole has a chrome ring around it, which looks sharp against the ebony surface!

Even though we thought that the chrome ring around the overflow hole was a good contrast, it might not complement the rest of your fixtures. Fortunately, you can remove this chrome ring and replace it, or simply turn the sink and set the overflow hole inwards!

10. Friho Undermount Bathroom Sink

If you are looking for a classic yet modern addition to your bathroom vanity, Friho brings you a classic rectangular sink with a contemporary appeal. Along with a convenient overflow design and ceramic material, it is durable and also easy to maintain. Lightweight and easy to install, Friho is an excellent choice for your vanity.

When it comes to finding an excellent rectangular undermount sink, you want one which is not too large, yet deep enough to fill in with water. Friho Undermount Bathroom Sink has just these features, making it a classic choice for your larger-sized vanities.

We found that the most suitable drain size for the Friho Undermount Bathroom Sink is 1-¾”. Although Friho does not include a drain with their undermount sink, you can choose to purchase any kind of pop-up drain which will complement the rest of your bathroom fixtures.

As you will find with most undermount sinks, the Friho also has a conveniently placed overflow hole – ensuring that excess water never spills out of the sink and onto the counter or floor.

Finally, the Friho Undermount Sink is made of sturdy ceramic material, giving it durability and resilience against most wear and tear. Additionally, the ceramic, crystalline glaze also adds a smooth shine to the sink, giving it a classy appeal in any vanity.

Overall, we noticed that the Friho undermount sink lived up to our expectations and can be an excellent addition to any vanity. However, we found that the drain was not perfectly shaped, and you might need to use plumbers’ putty to fix this slight issue.

Buying Guide For The Best Undermount Bathroom Sink

When selecting the best undermount bathroom sink, there are several factors to consider. A well-chosen sink can add a touch of style to a bathroom counter, and enhance the overall look of the space.

It is important to consider all of these factors carefully to ensure that the sink is both aesthetically pleasing and well-suited to the space.


When selecting what material to use for an undermount bathroom sink, consider the look and feel one is going for. Common materials include stainless steel, granite, and porcelain. Each of these materials has its own unique benefits.

Stainless steel is a popular choice due to its chip-resistant properties and its easy maintenance. Granite is a great choice for those looking for a luxurious look, as it is available in a variety of colors and is resistant to scratches. Porcelain is an affordable choice and is available in white, making it a great option for those seeking a classic look.

By investing in a sink that is made from high-quality materials, you can ensure that you have a sink you will love for years to come.


The weight of the sink is another key factor to consider when selecting the best undermount bathroom sink. Heavy sinks can be difficult to install and may need additional support or bracing. Lighter materials such as porcelain or fiberglass are usually easier to install and are a great choice for smaller bathrooms.

Additionally, the weight of the sink should be considered in relation to the countertop material. Make sure that the countertop is strong enough to support the weight of the sink and any items placed around it.


Undermount bathroom sinks come in a variety of colors, from classic white to more stylish grey and black. White sinks are a great option for those seeking a timeless look, as they are easy to clean and go with any style of bathroom. For those seeking a modern look, there are a variety of darker colors available, such as grey and black.

Moreover, some materials such as porcelain, are available in a variety of colors and designs, so one can choose the perfect option to match their style. 


Undermount bathroom sinks are available in a variety of shapes, from oval to rectangular. When selecting a shape, one should take into account the size and design of the bathroom, as well as the type of material used for the sink. For example, a round sink is ideal for a smaller bathroom, as it will take up less space.

Also, if one is using a granite sink, a rectangular shape may be a better choice as it will provide more counter space. 


You should take into consideration the size when buying an undermount bathroom sink because it’s easy to ensure that the sink will seamlessly fit with the surrounding countertop if the size is right. 

Also, the size of your bathroom and the space you’re working with should be taken into account when installing an undermount bathroom sink. This will ensure that your sink fits perfectly with the overall design of your bathroom.


The price of an undermount bathroom sink will vary depending on the material, size, and shape of the sink. Generally, stainless steel and porcelain sinks are more affordable options, while granite and other materials may be more expensive.

Moreover, one should consider the cost of installation hardware, such as brackets and clips, as these can add to the overall cost. 

Overflow Drain 

Another factor to consider is the overflow drain when selecting the best undermount bathroom sink. It is designed to prevent water from overflowing from the sink basin in the event of a clog.

This type of drain typically has a hole in the side of the sink basin that connects to a tube that runs down to a separate drain in the wall behind the sink. It is typically connected to the main sink drain, so if the primary sink gets clogged, the water will be diverted to the overflow drain.

In some cases, the overflow drain may be connected to a different drain in the bathroom, such as a shower or tub drain. It is important to regularly check and clean the overflow drain to ensure it is functioning properly.


Undermount bathroom sinks don’t just enhance the look of your new bathroom; they also come with a limited lifetime warranty, giving you peace of mind when installing one in your space. This will ensure that your product is covered in the event of any manufacturing defects.

Some of the best manufacturers even offer additional warranties that cover features such as finish and installation. Make sure to read the fine print before making a purchase, as some warranties are limited to certain products and may not cover all types of sinks.

Are undermount bathroom sinks easy to install?

Undermount bathroom sinks are typically easier to install than overmount or even drop-in sinks since they are mounted directly beneath the countertop. However, there are some factors to consider before attempting to install an undermount sink.

Firstly, it is important to make sure that the countertop is durable and strong enough to hold the weight of the sink. Secondly, the countertop must be properly sealed to ensure a watertight seal between the sink and countertop.

Lastly, the sink must be precisely measured and cut to fit the countertop. The installation process can be difficult and time-consuming, so it is best to hire a professional for the job.

What size of undermount bathroom sink do I need?

The size of your undermount bathroom sink depends on the size of your countertop and the space available. When selecting a sink, you must consider the size of the countertop, bathroom, space, as well as the other fixtures around the sink.

Most sinks come in standard sizes ranging from 18 inches to 30 inches in diameter, but custom sizes are also available. If you are looking for a smaller sink, then a 16-inch undermount bathroom sink is a great option.

What is the best depth for an undermount bathroom sink?

The best depth for an undermount bathroom sink is between 6 and 9 inches. This allows for plenty of space to wash your hands and brush your teeth, without taking up too much space.

Additionally, deeper sinks are more conducive to washing large items, such as pots and pans. If you have a large countertop, then a deeper sink may be a better option.

Which Brands Have the Best Undermount Bathroom Sink?

There are many great brands on the market that offer high-quality undermount bathroom sinks. Some of the most popular brands include Kraus, Kohler, and American Standard.

All of these brands offer durable, stylish sinks that are constructed from premium materials. Be sure to read online reviews and compare prices before making your purchase.


Most of us don’t think about bathroom sinks until we have to install one in our homes. Hence, it is crucial to research well, picking the best sink that goes well with the rest of your bathroom decor.

Enjoy the pleasure of having aesthetic, functional undermount sinks in your bathroom without spending a fortune.

On that note, we have come to the end of this comprehensive guide on undermount sinks. We hope we could help in clearing out your doubts and introducing you to some great products.

However, before signing off, we want to give you a quick recap of our findings. Having explored the best undermount bathroom sinks, we have compiled expert recommendations for our top three picks.
