Deciding whether to install a top mount or undermount sink is an important consideration when planning a kitchen renovation or upgrade. Both types of sinks have their pros and cons, so it’s important to evaluate your needs and preferences before making a decision. In this blog, we will explore the differences between top mount and undermount sinks to help you make an informed decision.

Top Mount Sinks

Top mount sinks, also known as drop-in sinks, are installed by placing the sink into a hole in the countertop and securing it with clips or screws around the perimeter. The lip of the sink sits on top of the countertop, creating a visible edge around the sink.


  • Easier installation process compared to undermount sinks
  • Can be installed on any type of countertop material, including laminate
  • More affordable than undermount sinks
  • Easier to replace or upgrade, as it doesn’t require any modifications to the countertop


  • The lip of the sink can trap dirt and debris, making it harder to clean
  • The lip can also make it more difficult to wipe water and spills from the countertop directly into the sink
  • The visible edge around the sink can interrupt the clean lines of a modern kitchen design

Undermount Sinks

Undermount sinks are installed underneath the countertop, creating a seamless transition from the countertop to the sink. The sink is secured to the underside of the countertop with adhesive and clips, which are not visible from the top.


  • Creates a seamless look between the countertop and sink, which can make cleaning easier
  • The lack of a visible lip makes it easier to wipe water and spills directly into the sink
  • Allows for more countertop space around the sink, which can be beneficial in smaller kitchens
  • Can enhance the overall design aesthetic of a modern kitchen


  • More expensive than top mount sinks due to the extra labor required for installation
  • Can only be installed on certain types of countertop materials, such as granite or quartz
  • Replacement or upgrades can be more difficult, as it requires modifying the countertop to fit the new sink

Ultimately, the decision to install a top mount or undermount sink will depend on your personal preferences and needs. If you’re on a tight budget and want an easy installation process, a top mount sink may be the better option for you. If you prioritize a seamless design aesthetic and ease of cleaning, an undermount sink may be the way to go. Consider your countertop material, cleaning preferences, and overall design goals when making your decision.
