Differences between Overmount and Undermount Kitchen Sink

20 April 2022

Overmount and undermount kitchen sinks are both stunning. There are many factors when it comes to choosing a kitchen sink, these include: size, depth, dividers and materials. In addition, your countertop material will be a huge factor in making this decision.

Undermount sinks are usually more popular for their looks whereas overmount sinks are better for longevity and for kitchen worktop materials such as wood.

Undermount Kitchen Sinks

These kind of sinks sit under the kitchen worktop, their edges are below the countertop. Below are a few types of undermount sink installation:

1. Positive Reveal: Kitchen counter ends before the edge of the sink producing a ledge.
2. Negative Reveal: Kitchen counter will overhang the sink.
3. Flush: Kitchen counter and sink are aligned perfectly.
