Undermount Sink vs. DropIn Sink


Choosing the right sink for your bathroom can be a daunting task. With so many options available in the market, it’s important to understand the difference between drop-in and undermount sinks. In this article, we will explore the pros and cons of both types to help you make an informed decision.

What is a Drop-In Sink?

A drop-in sink, also known as a top-mount or self-rimming sink, is installed by dropping it into a hole cut out in the bathroom countertop. The rim of the sink sits on top of the countertop, providing a finished look. It is the most common type of sink found in bathrooms.

Advantages of a Drop-In Sink

One of the main advantages of a drop-in sink is its ease of installation. Since it sits on top of the countertop, it doesn’t require any additional support or modifications to the cabinet below. It is also relatively easy to replace or upgrade in the future.

Another advantage is that the rim of the sink helps to prevent water from spilling onto the countertop. It acts as a barrier and contains any water that may splash out of the sink.

Disadvantages of a Drop-In Sink

One of the drawbacks of a drop-in sink is that the rim can be difficult to clean. Dirt and grime can accumulate around the edges, requiring extra effort to keep it clean and hygienic.

Additionally, the rim of the sink can take up valuable counter space, making it less functional for smaller bathrooms. If you have limited space, a drop-in sink may not be the best option.

What is an Undermount Sink?

An undermount sink is installed underneath the bathroom countertop, creating a seamless and sleek look. It is secured to the underside of the countertop using clips or brackets. This type of sink is growing in popularity due to its modern and minimalist design.

Advantages of an Undermount Sink

One of the main advantages of an undermount sink is its aesthetic appeal. The seamless design creates a clean and modern look that complements any bathroom decor. It also allows for more counter space, as there is no rim to take up valuable real estate.

Another advantage is that cleaning is much easier with an undermount sink. Since there is no rim, there are no crevices for dirt and grime to accumulate. Simply wipe the countertop and the sink is clean.

Disadvantages of an Undermount Sink

The main disadvantage of an undermount sink is the installation process. It requires professional installation as the sink needs to be securely attached to the countertop. This can add to the overall cost of the sink.

Another disadvantage is that undermount sinks are more prone to water damage. If the sink is not properly sealed, water can seep into the countertop and cause damage over time. Regular maintenance and resealing may be required to prevent this.


When choosing between a drop-in sink and an undermount sink for your bathroom, consider factors such as ease of installation, cleaning, counter space, and overall aesthetic appeal. If you value convenience and easy installation, a drop-in sink may be the right choice. However, if you prefer a modern and seamless look with ample counter space, an undermount sink is the way to go. Ultimately, the decision depends on your personal preferences and the specific needs of your bathroom.
