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.
There are other options, such as a positive or negative reveal. A positive reveal exposes a small lip of the undermount sink at the very top when it joins with the countertop; a negative one is exactly the opposite, where the counter extends slightly over the sink basin.
Undermount sinks are recommended for granite, solid surface and quartz countertops, but may not be as effective with laminate. They can be more expensive than drop-in sinks.
OVERHANG - The countertop extends over the edge of the sink on all sides by approximately 1/8" - 1/4". Use caution with this installation to be sure that accessories such as colanders or cutting boards will fit properly. REVEAL - The countertop edge sits approximately 1/8" - 1/4" back from the edgeof the sink rim.
Select a high-quality, waterproof silicone caulk specifically designed for kitchen use. This type of caulk provides excellent adhesion and flexibility.
The silicone will help hold the sink in place and ensure a waterproof seal. Avoid putting a bead that is too thick around the edge, as a significant amount of silicone is pushed out of the gap and onto the surrounding area. You will want just enough to cover the rim when pressed against the counter.
Mounting an undermount sink to granite involves using sink clips and fasteners. Apply epoxy adhesive, attach the sink clips to the sink's rim, tighten them uniformly, and secure the sink to the granite countertop.
Looking at a typical top- or under-mount sink, the depth tends to be 22″ if the holes are provided. The manufacturer suggests the front of the sink be placed 1½” from the front edge of the counter or even 2″. This leaves ½” to 1½” from the back of the sink itself to the wall depending upon the counter depth.
Countertops with undermount sinks installed are much easier to clean—in fact, this is why many people choose undermount sinks in the first place. There is no lip obstructing the sink, meaning you can sweep food particles directly into the basin without them getting caught.
The system includes 6-8 bolts, clips, and wing nuts. The bolts are inserted into grooves that the fabricator drills or cuts into the back of the counter, spaced evenly around the flange of the sink. The clip is then attached to the flange and tightened to secure the sink to the counter top.

Stainless steel sinks are widely regarded as one of the most durable options for undermount kitchen sinks. They are resistant to corrosion, stains, and heat. Granite composite sinks, made from a blend of crushed granite stone and resin, are also highly durable and resistant to scratches, chips, and stains.
Negative Sink Reveal
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.
Adhesive deterioration: Since adhesives break down over time, a sink can fall if it's no longer secured. Improper installation: The sink may not have been installed properly. Corroded hardware: Hardware, like mounting clips, can corrode and fail to secure a sink.
The most popular materials for undermount sinks are granite and quartz. However, there are other options such as marble, soapstone, and even concrete.

Streamlined and Modern Look: Unlike drop-in sinks, undermount kitchen sinks don't rest on top of the counter. They are installed underneath the countertop, creating a seamless and sleek appearance. This design choice enhances the overall style of your kitchen, giving it a sophisticated and contemporary feel.
Placement of Faucet
Product specifications often provide the setback distance, typically ranging between 2 to 4 inches, essential to consider. It's crucial to ensure that the faucet connectors beneath the countertop have ample space to clear the sink's base.
A dual mount sink has a flat rim that is usually just the thickness of the material, except for Quartz sinks which will have a thicker rim. They can be installed either above as a drop-in or below as an undermount, making it a versatile choice that can be installed in any countertop.
It's very important to install an undermount kitchen sink before the countertop slabs are set down. Once the countertop slabs are set down, you usually will not be able to fit the sink through the hole, and you won't be able to properly seal between the sink and the underside of the countertop.
In such a scenario, you may use silicone glue and epoxy to attach the sink to the countertop of your kitchen cabinetry. The following are the procedures to follow to install an Undermount sink in your kitchen without the use of clips or brackets.
