An Undermount Sink – What Is It?

The term, undermount, means under the countertop, which is exactly how this sink is installed. Compared to other types of sinks, which are usually dropped in the cutout on the countertop, an undermount sink is perfectly installed under the countertop, which makes the rim of the sink not visible outside.

Since the sink is mounted underneath the countertop, the overall look of the sink is seamless and nicely blends in with the countertop. “Camouflaging” with the countertop can get you a modern and minimalist look.

And also, it is one of the best ways to save space on your countertop. Following is the image of an undermount sink, so you can get an idea of how it looks in person.

How to Choose an Undermount Sink

How to Choose an Undermount Sink

1. Kitchen and Sink Size

Before starting your renovation project, measure your kitchen countertop and the surrounding area. Not knowing what size fits well can lead to a waste of time and money. Take a measuring tape and measure the countertop’s length, width, and height. 


Also, make sure you have enough clearance under the countertop for easy installation. This also helps to accommodate deep pans and pots for easy cleaning. 

2. Sink Material

Sink Material

After the measurements, next is the sink material. The material that you choose must satisfy your existing kitchen design, and not deviate from your expectations. 


Like other sinks, undermount sinks are also available in an array of materials, such as fireclay, stainless steel, cast iron, copper, concrete, and even granite and marble. 


Remember, each material has its perks. There is no such thing as bad material. For example, copper can be sturdy compared to porcelain, but it is expensive. Select the material that can blend in with the style of your kitchen greatly. 

3. Bowl Construction

There are two types of bowl constructions. One is a single-bowl and the other is a two-bowl construction. One-bowl constructions are more common, and give you an ample amount of space to work comfortably, but the two-bowl construction is mainly for multitasking. 


If you want more of a multitasking experience, try a two-bowl construction. If not, in that case, it is better to choose the single bowl, simply because of the greater amount of space it provides. 

4. Design and Style

Kitchen Sink Design and Style

Choose the style that does not stand out so much in your kitchen. Even though our main objective is to make the sink the focal point in the kitchen, it is better to choose a style that is not an over-the-top design and style. 


Undermount sinks come in a number of shapes, such as rectangular, circular, squared, and even oval-shaped, so it is easy to choose the design you think looks best in your kitchen.

5. Sink Depth

Probably one of the most important parts of the sink is the depth. It is the indicator that shows how many dishes it can hold at a time. Bigger is better when it comes to the kitchen sink.  


If possible, and if your kitchen countertop allows, try to get a deeper undermount sink. This, however, can affect ergonomics if a shorter person uses it. 


Based on your comfort level, choose wisely the depth of your sink.

6. Check if It Goes Well with Your Countertop

Always choose a sink that matches your countertop and also some sink material that can elevate your existing countertop look to a new level. One important thing you need to consider is the weight distribution. 


If you are going for a heavy-material sink, such as copper or granite, make sure that the countertop can manage your new sink’s weight. 

7. Soundproof

Soundproofing Kitchen Sink

Soundproofing may sound out of place with a kitchen sink, but it is a necessary one. It is understandable if you get frustrated with the sound of water or dishes clashing with each other. 


Having a sound dampener can reduce the noise and allows you to comfortably get the work done. 

8. Budget

One of the important factors in buying a sink is the budget. Your budget decides what features you can expect from your new sink. 


For example, copper and granite can look fantastic and has high longevity, but it can be expensive. Porcelain and acrylic can be inexpensive, but they do not have much durability or longevity comparatively. 


If you want an inexpensive sink, you might have to sacrifice some features. But investing in a good sink can give you something that lasts longer and can get you a good resale value for your home down the line. 

9. The Installation Process

Last but not least is the installation process. Most of the time, the installation processes are similar. But, heavier sinks require some additional support, such as sink clips. 


Make sure you have the right tools for the installation process and have enough space on the countertop to install the sink properly in its place.
