A More Seamless, Cleaner Countertop Look

An undermount kitchen sink allows your countertop to stand out. Instead of breaking the surface line, the sink sits quietly beneath it, letting the stone, wood, or concrete take center stage. The result is a kitchen that feels polished and thoughtfully designed rather than busy.

Easy Cleaning and Maintenance

One of the biggest advantages of our kitchen sink undermount design is how easy it is to keep clean. Without a raised rim sitting on the counter, there are fewer places for debris, water, or grime to collect.

Benefits include:

Wiping food scraps directly into the sink
Fewer seams around the sink edge
Less buildup around the countertop cutout
Easier maintenance over time

This makes undermount sinks a popular choice for homeowners who value both cleanliness and design simplicity.

Copper Undermount Sinks

A copper undermount sink brings warmth and character to the kitchen while maintaining a clean, modern profile. Copper is naturally antimicrobial and develops a rich patina over time, making it both practical and stunning to look at.

CopperSmith offers copper undermount sinks in specific finishes and textures, including polished copper, aged copper, and rustic copper. These variations make it easier to match the sink to cabinetry, hardware, and overall kitchen style.

Stainless Steel Undermount Sinks

Stainless steel undermount sinks are built for durability and daily use. The material handles heavy cookware, resists corrosion, and cleans easily after cooking and cleanup.

CopperSmith offers stainless steel undermount sinks in multiple sizes and bowl configurations, allowing customers to choose a layout that fits their kitchen and cooking habits. These sinks are often selected for modern homes, busy households, and commercial spaces where durability matters.

Undermount Sink vs Overmount Sink

You may wonder which is the best option for you: an undermount sink or an overmount sink. The right choice depends on both design preference and practical needs.

Undermount Sink Advantages

Allows direct wiping from the counter to the sink
Keeps the countertop surface uninterrupted
Works well with stone and solid-surface counters
Creates a cleaner, more intentional look

Overmount Sink Considerations

The rim sits on top of the counter
Easier to install with laminate countertops
Rim remains visible around the sink opening

Can Undermount Sinks Be Workstation Sinks?

Yes. Many undermount designs can also function as a workstation sink. These sinks include integrated ledges that support accessories such as cutting boards, colanders, and drying racks.

An undermount workstation sink combines the clean installation style of an undermount sink with the functionality of a workstation, making it ideal for kitchens where efficiency matters.

Choosing the Right Undermount Sink

Here’s how to choose the right undermount sink for your kitchen:

If you cook often, choose a deeper basin to handle large pots and reduce splashing.
If you prep meals daily, consider an undermount workstation sink with cutting boards and colanders.
If you want a warmer, rustic look, copper undermount sinks with hammered or antique finishes work well.
If you prefer a clean, modern kitchen, stainless steel undermount sinks offer a straightforward option.
If your kitchen is smaller, CopperSmith offers undermount sinks in a range of sizes to fit compact layouts.

Each sink can be customized by size, bowl configuration, and finish.

Frequently Asked Questions

Do Undermount Sinks Work in Farmhouse Kitchens?

Absolutely. You can get undermount farmhouse sinks in particular that work beautifully with farmhouse and rustic styles while keeping the look clean and refined.

Are Undermount Sinks Harder to Install?

Usually, undermount sinks attach from below the countertop using clips, brackets, and adhesive like silicone or epoxy, requiring precise cutting of a hole that matches the sink rim exactly. If you’re uncomfortable completing the project, you may choose to hire a specialist to install your undermount sink.

What is an under-mount sink?

Undermount sinks get their names from their unique installation, which is fastened under the sink countertop so the edges of the sink sit below the level of the countertop, rather than above. Here at Coppersmith, we offer a wide variety of styles, sizes, and materials of under-mount sinks so there is something for every homeowner. They come in a variety of materials including copper, stainless steel, and cast iron. As well as single or double bowl.

Are under-mount sinks easy to install?

Undermount sinks tend to be a bit more difficult to install because they are designed to fully be placed under your countertop. Some countertops will not work with an undermount sink so this is an important factor to keep in mind. Improper installation can lead to damage or a leaky faucet so it’s best to have professionals install an undermount sink if you are not familiar with the process.

How do you install an under-mount sink?

Undermount sinks are installed by being mounted underneath the countertop and one's cabinets. This gives them a sleep look with an invisible rim. Most under-mount sinks do not come with pre-drilled holes, allowing you to choose exactly where you want to place your faucet. It is important that the installation process of an undermount sink is done properly, although Coppersmith does not offer installation services we can direct you to resources with some of the leading professionals for installing your under-mount sink.

What are the benefits of an under-mount sink?

There are numerous benefits of an under-mount sink that make them easy to clean and the optimal choice for many homeowners. Undermount sinks sit with their edges under the counter rather than raised around the edges. This is great for cleaning and avoiding getting water, crumbs, and other food particles trapped under the sink and countertop. Another benefit of under-mount sinks is that they are very customizable, coming in a wide variety of shapes, basin depths, and materials. Including copper, stainless steel, cast iron, and porcelain. Their seamless edges prevent moisture from getting trapped and keep away water spots and damage over time. This lack of edges around the sink will also give you more counter space for all your necessary kitchen needs.

What are the cons of an under-mount sink?

Although there are numerous benefits of an under-mount sink, the process of installation can be a barrier for some people. Unfortunately, with an undermount sink, there needs to be adequate counter and cabinet space below the countertop as this is where the sink will be placed. Sometimes counters do not have enough space or foundational strength to support an under-mount sink. Undermount sinks can also be tougher to change in the future. This is because, during installation, a custom-sized hole must be cut under the counter to fit your undermount sink into place. If done right, these are very durable and will last a long time, but may be harder to replace in the future if need be.

Will under-mount sinks ruin my counter from the installation process?

Undermount sinks won’t ruin your counter as long as the installation process is done right. The one thing that may be a barrier is if you wish to change or replace your sink in the future. Undermount sinks require a custom hole to be cut underneath the countertop, so keep this in mind when taking measurements for your undermount sink to be installed.

What is the difference between an under-mount sink and a standard sink?

An undermount sink is primarily how it is installed and sits in the counter of the sink. With a standard sink, the edges are usually raised and sit around the outside of the sink making it easier for food and water to get trapped.

How do I measure an undermount sink for installation?

The hole for your under mount sink should be the same size as the actual sink, minus the rim. Taking proper measurements from one rim to the opposite rim of your sink both length and width, and then subtracting the length of the rim itself will give you an approximate size of what you’re working with. The overall width of the sink rim should be equal to or less than the interior width of your sink cabinet. This will allow for easier installation and replacement of the sink.

What kind of sealant should I use for an under-mount sink?

It is important that your undermount sink is sealed properly during the installation process, which can be one of the more difficult steps. Over time, 100% silicone-based sealant is found to have the best use and prevent cracking or breakage. When a bracket is installed, almost any type of water-tight sealant will be functional. We often utilize siliconized acrylic caulk because it is water-based, long-lasting, and much easier to apply.
