3 Types of Undermount Sink Reveals (2025)

If you end up deciding that the undermount option is right for you then your decision will be choosing the reveal. The reveal outlines how much of the undermount sink is noticeable below the countertop. Your sink can be mounted in these three different types of reveals: zero, positive, or negative. Let’s go over the three undermount sink reveals that are currently available.

Zero Sink Reveal

A zero reveal allows your countertop to be flush to the sinks rim. It is also the most visually appealing of the three as well as the most practical. This reveal is free from the overhangs that have cracks and crevices where trash can get stuck and then become hard to clean.The zero reveal requires the fabricator be highly precise with their measurements in order to achieve the perfect fit.

Positive Sink Reveal

A positive reveal is when the edge of the countertop sits back exposing a portion of the sink’s rim. In most cases, the countertop will sit back 1/8th of an inch from the edge of the sink. Some customers like this feature because they can use this to their advantage by resting acutting boardor a colander on the rim. The only drawback is that if the reveal is not cleaned regularly food, grim, and debris can build-up overtime. If the positive reveal is something you like because of the accessories you are able to utilize, then you might want to consider aworkstation.

A workstation provides you with a zero sink reveal and the sink comes with a built-in ledge which allows you to use accessories such as acutting board, roll up drying mat, and a colander. You get the best of both worlds with a workstation.The positive reveal allows fabricators to have more leeway when installing the undermount sink.

Negative Sink Reveal

A negative sink reveal is when the countertop hangs over the edge of the sink on all four sides. In most cases, the countertop will extend about 1/8th past the sinks edge. A majority of customers go with this reveal because it is the most visually appealing of the three. The reason why most people like the negative reveal is because the countertop completely hides the rim of the sink. The only draw back to this reveal is that if your countertop is more susceptible to chipping you run the risk of having these problems occur later down the line. The negative reveal allows fabricators to have the most leeway when fabricating the sink cutout as well as when installing the undermount sink.
