Since undermount sinks to not have anything above the counter to help carry their weight, they need more support. They also need more solid countertops that don't suffer easily from water damage. This often makes them a more expensive sink than other options and also makes installation more difficult.
Undermount sinks are often a no-brainer decision when remodeling a kitchen. There's lots to love: they look nice, let you to wipe water and crumbs directly from the counter into the sink with a single swipe, and they eliminate that gunk-magnet seam around the lip of overmount sinks.
Undermount sinks are a popular choice for many homeowners because they offer a sleek, seamless look that is easy to keep clean. Because there is no lip around the edge of the sink, it is easier to wipe debris directly into the sink, rather than having to clean around the rim of the sink.
The under-counter basin is easier to clean, easy to clean and hygienic, and the sanitary corners can also be seen clearly. But the disadvantage of the under-counter basin is that the construction is more difficult, and the bearing capacity is not as good as that of the over-counter basin. It is troublesome to install.
When you have a negative reveal, a portion of the countertop underside is exposed to splashing water. When you use a porous material, water can seep through and the sink area can become a breeding ground for mold.
Many undermount sink types are attached to the countertop with silicone sealant and metal clips. Use a utility knife to cut through the silicone, then unscrew the clips. Removing and installing an undermount sink is a two-person job.
Some say drop-in is generally the best option because it's easier to access all parts of the sink for cleaning. However, both types of sinks tend to accumulate grime along the caulk line where the sink meets the counter. Where an undermount sink rim and counter meet, the caulked gap can be trickier to clean.
A common issue with the undermount design is that they can be prone to sagging over time. When the sink starts pulling away from the countertop, leaving a gap, it needs to be hiked back up and secured in place. Undermount sinks work best with solid granite, marble, or concrete counters.
The lack of a visible lip with an undermount sink makes it quite a bit easier to clean your counters; you can sweep any debris from your counters right into the sink. However, top mount sinks are the simplest of the two types of sink to keep clean themselves.
An undermount kitchen sink is easier to clean. Since your countertops are below your sink, there will be little need for scrubbing them. You will also have less counter space, so cleaning will take less time. With less counter space, you will also have less waste from pans and pots.
Weight: Stainless steel or copper sinks tend to be the lightest, while vitreous china, porcelain, ceramic and composites are moderately heavy. Choose a heavy stone, cast iron or enameled-steel undermount sink only if you're sure the countertop can support the weight.
Undermount sinks are not much more expensive than other varieties of sinks, but the installation can cost more. For budget undermount sink options, choose a smaller size and a material like acrylic, stainless steel, a composite stone, or porcelain. These sinks are lighter than natural stone and more budget conscious.

The oval sink is also the most practical sink shapes amongst undermount sinks. The oval shape allows the sink to be wide without having to take as much space on your counter as the rectangular sinks. In addition, the vast majority of oval bowls swoops down which allows for better drainage than the flat bottom sinks.
The stronger the silicone bond, the harder it would be to remove the sink without causing your granite countertop some damage. While old silicone bonding can be removed using a knife, there are certain spaces that won't allow you to do this without actually lifting the granite countertop.
