What Is An Overmount Sink?

So, it’s essential to pick the best option for your kitchen and needs. This article reviews overmount sinks to help you decide if this sink style is best for your home, so stick around to learn more!

What Types Of Sinks Are There?

There are quite a few different types of kitchen sinks available on the market today. Certain types are better than others for specific scenarios, but each option has its place. A few of the most common sink types include:

  • Top mount (aka overmount sinks): This is the most common type of kitchen sink. You simply install it into a pre-cut hole in the countertop. The broad rim of the sink rests on the countertop, which gives it plenty of support. 
  • Undermount: These sinks can be tricky to install on particular countertops, as they are attached underneath the countertop. They’re popular because they create a seamless look between the area around the sink and the sink itself. The lack of a rim resting on the counter gives extra counter space, which is perfect for tiny or compact kitchens. Cleaning the counters is quick and easy since there isn’t a lip on the sink. 
  • Bar or prep sink: These sinks are small and shallow and are best for cleaning produce, prepping foods, or draining pasta. They often have small faucets and sit alongside a larger sink, on a kitchen island, or in a bar area. 
  • Apron-front (farmhouse): These sinks are trending because of their rustic, old-world charm. The front of the sink is exposed, while the back and sides are undermounted. These sinks are often much larger than traditional kitchen sinks, with deeper bowls and a wider area to work in. 
  • Flush-mount: Also known as integrated sinks, flush-mount sinks blend seamlessly into the kitchen layout. They don’t have any visible edges or inconsistencies in material. They’re particularly common in bathroom vanities, but they may be custom-ordered for the kitchen as well.

Overmount sinks, also known as top-mount sinks or drop-in sinks, are among the most popular types of sinks. They have a lip that rests on the countertop, covering a small portion of the counter around the sink. This gives it extra stability and an extremely easy installation process. 

Pros And Cons

Like every other type of sink, overmount sinks come with a few specific pros and cons. A few of the high points of overmount sinks include:

  • Quick and easy installation, great for DIYers
  • Usually more affordable, even with professional installation
  • Great for various countertops, including porous counters or those that aren’t solid and need extra protection (such as butcher block counters)
  • Widely available, can be bought from most home improvement stores
  • Hundreds of finishes, styles, and designs

On the flip side, a few cons of overmount sinks include:

  • The elevated lip disrupts the seamless countertop appearance.
  • Water and food particles may collect around the edges, which can result in mold. Proper sealing is essential.

What Is The Difference Between An Overmount And An Undermount Sink?

The primary difference between overmount and undermount sinks is indicated by their names. Overmount sinks have a lip that rests on the edge of the countertop, which makes installation quick, easy, and straightforward. 

On the other hand, undermount sinks need to be attached to the underside of the kitchen countertop. Generally, this is done using a two-part epoxy adhesive. Once they’re attached, they need to be sealed with silicone caulking around the perimeter. 

In some cases, installing an undermount sink can be tricky, especially when you’re working with certain countertops. However, if you’re up for a DIY project, installing an undermount sink is doable. If not, most professionals can have the installation done in 30 minutes or less.
