Need a quick decision? Here's our top picks:

What is an Undermount Kitchen Sink?

An undermount sink is installed from below the countertop instead of dropped in from above. Unlike a drop-in sink, which has a visible rim where the rest of the sink rests, an undermount sink comes mounted flush with the countertop above.

This type of installation creates a sleek, uninterrupted line when viewed from above. The sink then gets secured into place with silicone glue and mounting brackets. Once installed, an undermount sink shows no signs of hardware when viewed from above, and it has a finished and polished appearance.

Since they sit flush with the counter's lip, crumbs can get easily brushed into the sink, which makes cleanup easy and fast. Because they do not have a broad rim, an undermount sink sometimes requires extra support in the cabinet below.

How to Choose the Best Undermount Sink for Granite Countertops?


  • Natural Stone: Natural stone like quartz or granite make extremely durable sinks, but can be heavy to install. They are also "unfriendly" to dishes and can cause shattering on contact.
  • Porcelain Enamel: Porcelain enamel sinks are sleek and classic. Usually, these sinks come in a fresh white color and have a polished glaze that will keep shining for a long time. However, this material is somehow prone to scratching and chipping over time.
  • Copper: Copper sinks are a unique choice that can be a real conversation starter in your home. They do change color with age and naturally require special care and cleaning.
  • Plastic: A great budget choice! Plastic sinks are durable and can stand up to heavy use. They can collect stains and scratches over time and may not match the granite countertops' high-class look.
  • Stainless Steel: Stainless steel is a timeless choice for virtually any type of countertop. Because it resists rust, stainless steel lasts a long time and always looks professional and clean.


Your sink's size depends on what you intend to use it for and the usage period. Large farmhouse single-bowl sinks can be great for those who frequently maneuver large items in or out of the sink. However, a double-bowl setup can be appealing to those who love multitasking. Larger sinks often take longer to drain and wipe down, and they also take longer to fill. Smaller undermount sinks could be quicker to clean, but you may have to compromise on space.

Installation Extras

The best granite countertop kitchen sink gets installed as an undermount and features lightweight and durability. However, some sinks made of denser materials like natural stone or fireclay can be very heavy and require extra support within the cabinet. With the heaviest sinks, a cabinet must get tailored to fit the sink instead of vice versa, which may be a hassle and require extra planning.


The kitchen sinks with granite countertops should blend well with the room's existing colors and complement the kitchen's interior décor. The color of your sink may be one of the most critical factors in choosing a sink, especially when it comes to coordinating with granite countertops. Granite has a distinctive appearance and deserves to be complemented by the best materials. Choose a color that will highlight your granite countertops.


When homeowners put in granite countertops, they usually want these counters to be the kitchen star. Choosing a sink that upstages the granite countertop may not be a great idea, though plenty of personalities can get found in a sink. It's best to pick a sink that will jive with your decor while remaining understated.


Depending on what you are using it for, it must also accommodate your chores and create more workspace if necessary by covering the top with the rack accessory. Don’t forget its durability, ideal size, and resistant from scratch, stains, chipping, rust, and corrosion. Also, pay attention to the finish and the nonporous nature. Consider the factors described above if you want to buy the best undermount kitchen sink for your granite countertop for optimal results.
