How to Choose Undermount Kitchen Sinks

Sinks are necessary in any kitchen. That much everybody knows. But what are undermount kitchen sinks? How are they different or similar to standard kitchen sinks?

Are they better? Worse?

Find out in this guide to undermount kitchen sinks.

Undermount kitchen sinks: A buyer’s guide

Like with standard kitchen sinks, there are a lot more to undermount kitchen sinks than a device that catches water that comes out of a faucet.

There is no sense in putting in a brand new undermount kitchen sink or replacing your standard kitchen sink with one without knowing what to consider.

If you install an undermount kitchen sink for one or two lofty reasons that do not address its function as well as its aesthetics, there is a good chance that you have selected an undermount kitchen sink that is not completely optimal. 

This means that the undermount kitchen sink that you selected may not last in the long term.

When you select an undermount kitchen sink, you need to do so with the intent that you will be able to use it for a very long time. You should also be interested in having it look impressive and in-style for a very long time as well.


Let’s start with the most obvious.

Just like with standard kitchen sinks, size is definitely a factor to consider when selecting an undermount kitchen sink. The optimal size for your undermount kitchen sink is almost completely dependent on how big your kitchen is, how big your counter is, and what you intend to use the sink for.

Don’t forget that it does take a decent amount of counter space to get any kitchen sink put in, undermount or not. This is likely the very first thing that you should account for.

Although undermount kitchen sinks do clear up a little bit of counter space, you should still understand how much of the counter you are taking up when you get an undermount kitchen sink put in.

However, your undermount kitchen sink should be large enough to fit more than one pot or pan. There is nothing more frustrating than possessing a kitchen sink that does not fit enough cookware or other kitchen and cooking related materials.

From this, you need to choose a size that you believe will be optimal in the long term. Refuse the temptation to choose the smallest or largest kitchen sink.

Gauge/steel thickness

Most undermount kitchen sinks are made of steel. This protects it from the impact of everything that is dropped into it. There are varying degrees of how thick this steel is, and this can affect what can happen to your sink over time.

The lower the gauge levels of the steel, the thicker the steel is. From this, many argue that the thicker the steel is, the more optimized the kitchen sink will be in terms of function. Although the logical decision is to choose sinks with a steel gauge of 18 or lower, this may not always be the case.

There are instances where 18 or lower gauge of steel thickness may not be optimal for an undermount kitchen sink. For example, you need to have a certain budget just to possess an undermount kitchen sink with a very thick steel layer.

Also, you’ll need to be aware that kitchen sinks that have lower steel gauges will also be extremely loud when things are dropped in them.

These are two precautions that you should take when analyzing what kind of gauge level steel you want for your undermount kitchen sink.

Heat resistance

If you are the type who cooks constantly, you’ll want to pursue an undermount kitchen sink that can resist heat. Heat resistant undermount kitchen sinks not only maintain a clean look, but also last long. However, this does not need you shouldn’t clean and maintain heat resistant undermount kitchen sinks.

Hot pots, pans, and other kitchen tools can still cause markings on a reinforced and resistant undermount kitchen sink. This means you will still want to clean up after yourself after letting all of these hot kitchen tools come in contact even with a heat resistant kitchen sink.

Noise control/sound pads

Sinks can get loud when kitchen tools, silverware, plates and bowls are dropped onto them. Something that can prevent this are sound pads and insulating foam. If you are using your undermount kitchen sink a lot, you’ll want some way to prevent it from making noise.

Be aware, however, that these devices do cost extra and also count as additional features to any given undermount kitchen sink.

Undermount kitchen sinks do operate similarly to standard kitchen sinks. But they do possess a number of benefits in comparison.

Benefits of undermount kitchen sinks

The first thing that you need to know is that undermount kitchen sinks have the exact same function as standard kitchen sinks:

  • They are both appliances that manage your water use and funnel it through a drain so that you can cook, clean, and do anything else that involves water in the kitchen.
  • In its function, undermount kitchen sinks do the exact same thing that standard kitchen sinks do.
  • There are only a couple of real differences between the two, and these differences favor undermount kitchen sinks over their standard counterparts.
  • Standard sinks get directly attached over the edges of counters. They are mounted over the counter and often look very plain because of this.
  • Different than standard sinks, undermount sinks are, of course, mounted underneath the selected counter. This will make the counter that borders the sink look much better than it would if it contained a standard sink.
  • Another thing that separates undermount kitchen sinks from their counterparts is the fact that you can place its faucet anywhere. Faucets are usually installed alongside standard kitchen sinks, but they are installed separately when they have an undermount design.
  • From this, it appears that undermount kitchen sinks are optimal compared to their standard counterparts. 
  • However, standard kitchen sinks do possess two advantages over their standard counterparts. First, they are much easier to find and more common. And second, they are much easier to install.
  • Installing undermount kitchen sinks is a different process than installing standard kitchen sinks, and it can take some getting used to.

Frequently asked questions

Q: Which is better: Undermount sinks or drop-in sinks?

  • A: The answer to this question is directly related to how you want the sink to look relative to how everything else in the kitchen looks. Sinks all serve virtually the exact same function whether they are undermount, drop-in, or overmount. The difference between undermount sinks and drop-in sinks is that undermount sinks do not contain a surrounding border around your counter. The lack of this surrounding border can make an undermount sink look a bit more impressive.

Q: Is an undermount sink better than an overmount sink?

  • Undermount sinks may look impressive, but they are slightly less functional than their overmount counterparts. One of the better features of an overmount sink is that they are oftentimes installed similar to a three-compartment sink in most restaurants, where the sink unit does a little more than connect to brackets on a counter. This is optimal in its function, but they do not look as impressive as an undermount sink. One is not better than the other, they are both optimal for different situations.

Q: How is an undermount sink attached?

  • A: Undermount sinks are attached similarly to a drop in sink, but there is only one difference: They use supports and brackets. The only difference is that with undermount sinks, the brackets that hold them together are centered underneath the counter. With drop-in sinks, the brackets are located a little closer to the counter that attaches the sink. Attaching an undermount sink is not any more or less difficult than other sinks, just different.

Q: What adhesive is used for an undermount sink?

  • A: Undermount sinks use the same kinds of adhesive that other sinks use – Caulk. Caulk does two things: First, it holds everything involved in the sink together perfectly and for a very long time. Do not forget that sinks deal with water, and water can break certain things down. Caulk prevents the shelves and brackets that hold up a sink from breaking down. Caulk also creates watertight sealing that will prevent leaks.

Q: How much does it cost to install an undermount sink?

  • There are two “phases” of the installation process of an undermount sink. First, there is the cost of the sink itself. This varies, but it has an average cost of $285. Then there are plumbing labor costs, if they are necessary. Again, this varies from location to location, but the average of this is right around $400. In some situations, plumbing labor may not be necessary, especially if you are able to take the time and energy to do the research involved in the plumbing labor yourself.

How to install undermount kitchen sinks

Installing an undermount sink can be a bit tricky if you’ve never done it before, but with these simple instructions you’ll be able to install your sink in absolutely no time. After installing kitchen sinks, you may want to buy water softner for your house. Free Range LA helps you choosing this.

  • There is a much different process to installing undermount kitchen sinks than their standard counterparts.
  • It is not more difficult to install undermount kitchen sinks, just different.
  • An undermount kitchen sink still uses the same kind of parts that standard kitchen sinks use: Supports, brackets, and shelves are all things that are used by both types of sinks.
  • The only difference is how the components are employed and applied.
  • Installing the supports is the very first thing you should be doing when installing undermount kitchen sinks. You can do this using three types of sink supports: Commercial brackets, a custom wood frame, and a custom plywood shelf.
  • Of these three, commercial brackets are the most optimal and least complicated for an undermount kitchen sink. The other two methods are generally utilized when you are installing a standard kitchen sink.
  • The supports create the frame, which should then be caulked together after setting the sink onto the support frame.
  • The final thing you need to do is install the adjacent countertops over the sink. This should sandwich it between the countertop and cabinet frame.
  • The only real difference between standard sinks and undermount sinks is that an undermount sink does not extend over the counter the way that standard sinks do. 
  • This is why it is much easier to install it by connecting it to commercial brackets than by using frames. Frames almost rely on the kitchen sink having an overmount border.
  • The final part of the installation process of an undermount kitchen sink is caulking. Caulk must be applied to any given sink no matter how it is mounted, and it needs to be applied to flange of the sink.

Hopefully, after reading these reviews you’ve found the undermount sink that you’ve been looking for. If not, keep doing your research. An undermount sink is a great investment and they look absolutely amazing. If you have a difficult time installing your undermount sink, don’t worry.
