Undermount Kitchen Sinks Buying Guide

What Is an Undermount Kitchen Sink?

Unlike drop-in sinks, an under-mount kitchen sink installs in your kitchen from within the cabinet. You don’t place the sink in the countertop hole; instead, you apply silicone along its edges and place the sink in the cabinet below the cut-out in your countertop. 

You have to attach the mounting brackets from above and wait around 24 hours for the silicon to dry before using the sink. 

Why Buy an Undermount Kitchen Sink vs. Other Kinds?

Undermount kitchen sinks are a popular choice for both residential and commercial kitchens. They not only look good but also have many practical benefits. 

Here’s why they are better than other kinds:

Seamless Appearance 

Undermount Kitchen Sink

One of the top reasons why most homeowners opt for an under-mount sink is its clean lines. It sits below the kitchen slab, with no raised edge or lip interrupting the flow of the counter. 

A drop-in sink sits atop the counter, which ruins its overall appearance to some extent. 

With an under-mount sink, you get clean and crisp lines that increase the aesthetics and give your kitchen a modern and contemporary feel. 

Easy to Clean

The raised outer rim of a drop-in kitchen sink prevents the water from flowing back into the sink. All the water that makes its way under this edge becomes an excellent breeding ground for germs and other harmful microbes. These crevices also tend to gather dust. 

With an under-mount sink, this is not a problem. It features clean, sleek lines that do not interrupt the water flow. Also, the lack of crevices means no dirt accumulation, so you can clean it more easily. 

Free up Counter Space 

The edges of a drop-in sink take up about 2-3 inches of available counter space. On the other hand, an under-mount sink helps you save that valuable space by sitting within the countertop. 

While the 2-3 inches of space may not make much of a difference, it does come in handy for placing water filters, soap dispensers, etc. 

What to Look for in an Undermount Kitchen Sink

By now, you know that under-mount kitchen sinks come in various sizes, shapes, and finishes. A few models even boast some special features that make them unique. 

So, how do you find an appropriate one for yourself? In this section, we discuss some features to look for in an under-mount kitchen sink. 

Dimensions

The dimensions of the under-mount sink are always the first thing to look for. You don’t want to be stuck with a unit that is too big or too small to fit inside your cut-out. But, you also have to make sure it can handle all of your kitchen needs, including cleaning and cooking. 

To find the right size, first, measure your under-sink cabinet. 

Next, think of the biggest cooking pan or pot you use. 

Now, use it as a guide to find a suitable sink that will work with your available cabinet space, too. 

Gauge

Gauge refers to the thickness of the metal used in the construction of the sink. The lower the gauge number, the higher the thickness and vice versa. Most thin sinks have a 22 to 23 gauge, while thicker ones boast 18 to 19 gauge. 

Your goal should be to find a thick sink with a lower gauge. Such a model is not just durable and sturdy, but it is also quieter than its thin counterpart. 

Material

The material of an under-mount sink is another essential consideration. 

Most people actually pay more attention to the design without paying much attention to the construction material. But it should be the other way around. 

If you want to purchase a quality sink, you should first decide on its material and then choose the design. 

You’ll find under-mount sinks made with granite, steel, porcelain, and more. 

Each of these materials has its own benefits and shortcomings. We suggest you know about them first and then decide on the one you want to purchase. 

Heat Tolerance 

Different under-mount sink materials have different heat tolerance thresholds. 

For example, metal is highly conductive, so it easily heats up when exposed to hot water, while granite doesn’t heat up too much. 

It is important to find a sink with high heat resistance because a sink with lower heat tolerance is more susceptible to damage. 

Very high or cold temperatures can easily cause it to crack, bend, or melt. 

Noise Level

We are all too familiar with the obnoxious clanging noises of dishes and other objects hitting the side of the sink. The good news is, you can find an under-mount sink with a different kind of material that softens the noise. 

Plus, some models incorporate several noise reduction features, such as a special rubber padding that cancels noise or certain kinds of coatings on the base and sides of the sink to dampen the noise. 

You should also choose such a model and say to enjoy a much quieter dishwashing experience. 

Pros and Cons: Undermount Kitchen Sinks

Best Undermount Kitchen Sink

While an under-mount sink is great for keeping its contents hidden, certain problems discourage people from installing one of these in their kitchen. 

Here are both aspects of an under-mount kitchen sink to help you make an informed choice. 

Pros

  • Since they install from inside the under-sink cabinet, their rims are completely invisible
  • Generally deeper, which allows them to stay hidden
  • Cleaning is easier because there are no crevices or edges to clean 
  • Available in a wide variety of sizes and styles 
  • Freedom to decide faucet placement 
  • Add to the style and overall aesthetic of your kitchen

Cons 

  • Generally more expensive than drop-in models 
  • Tricky and complicated installation  

Cleaning and Maintenance: Undermount Kitchen Sinks

Now that you have a shiny new under-mount kitchen sink, it’s important that you clean it to maintain its luster. 

Here are some tips for cleaning and maintaining your under-mount kitchen sink: 

  • Regardless of its material, you should clean a kitchen sink immediately after using it. This prevents limescale build-up and rusting. 
  • Always clean the sink in the direction of brushing. Look at it from an angle to find the right direction. Never use circular movements as they can permanently change the surface structure. 
  • To get rid of limescale build-up, use some vinegar or lemon-based cleaning agent. 
  • Give your stainless steel sink a basic clean with a suitable polishing agent every 3 to 4 weeks.
  • Never use aggressive cleaning agents, steel wool, prickly brushes, or bleach containing hypochlorite to clean your sink. These materials can permanently damage your sink’s surface. 

Undermount Kitchen Sinks: Frequently Asked Questions

Are Undermount Kitchen Sinks Reliable? 

Yes, under-mount kitchen sinks are extremely reliable. 

Although this depends upon the strength of the glues and adhesives used in its installation as they hold the sink in place, the products available these days have strong adhesive chemicals. They are capable of forming a virtually unbreakable bond, making the sink both secure and stable. 

Can you replace an under-mount sink without removing the countertop?

Sure, you can replace an under-mount sink without removing the countertop. But, the job is complex and tricky, so we recommend getting a professional granite expert to carry out the replacement. 

What should I use to seal my under-mount kitchen sink?

Whether you install the under-mount sink yourself or hire a professional, it is important to seal it to prevent water from getting into the gaps. You can use good, waterproof silicon along the edges and caulk to seal it against water damage. 

How is an under-mount sink held in place?

Heavy-duty clips and caulk or a special adhesive hold an under-mount sink in place. These are applied on the rim of the sink and securely attach the rim to the underside of the kitchen countertop along the sink cut-out. 


Final Verdict: What is the Best Undermount Kitchen Sinks Sold Today?

An under-mount sink really makes the transition between the sink and the countertop smooth and seamless, making it a great investment.
