10 Best Granite Composite Kitchen Sinks
for December 2023

The Ruvati RVG1033BK sink is a good-looking, reliable workhorse of a kitchen fixture. It's constructed from 100 percent granite composite, so it's slightly heavier than similar sinks made with other materials, but it's extremely scratch-resistant. The sink comes with matching drain, so it's easy to add a separate soap dispenser or extra faucet. The sink has pre-drilled holes for 3.5-inch drains, but we tested it with an old, smaller sink drain, and we didn't notice any leakage or seepage. The sink comes pre-assembled, so all you have to do is unbox it, attach the drain, and install it. There's a hole in the back of the sink for a water hookup, so you don't need to drill any holes for plumbing. The sink's 16-1/2-inch width and 9-inch depth make it well-suited for small kitchens, and the sloped bottom makes it easier to clean up any food that splashes onto the sink. The sink has a smooth and shiny finish that looks a little plasticky, but nothing a good soap and water scrub can't handle.

This attractive sink has a durable, hard, non-porous surface that is heat, scratch and chip resistant. It's also easy to clean, thanks to a deep basin and 1.5-in. drain. The sink is also easy to install, thanks to the four pre-drilled faucet holes. The sink's dimensions are 33-inches x 22-inches x 9-inches deep, so it's smaller than some of the other sinks we tested. However, this sink's smaller size makes it easier to use in smaller spaces. The Buckingham sink is also less expensive than our other top pick, the Kohler K-2189-0 Purist, and it's slightly thicker, so it ships a little heavier. The Buckingham sink comes with a 1-year limited warranty.

The sink's granite composite construction means that it is designed to be durable and stain-resistant. The sink's surface is colored all the way through, which helps prevent stains from setting in. The sink's size and shape, which is the same as our top pick, means it will work with nearly any faucet and plumbing setup. The only potential drawback we found is that the sink's bottom edge is high enough that it can be tricky to clean around. The sink's pre-drilled holes are standard 1-3/8 inches in diameter, but if you're planning to use an aftermarket faucet, you'll need to get a faucet with the required size. The sink's pre-drilled holes are also plugged with silicone stoppers, which can be removed. The sink's cutout template and mounting clips make installation simple.

The sink is also colored all the way through, so what you see is what you get: no unsightly laminate edges. The sink has a premium look and performs well, with smooth, tight corners and a sturdy feel. The sink is pre-drilled with a hole for standard faucet installation and a 4-hole sink grid that accommodates most any size faucet. The grid is detachable, and the sink comes with a folding drying rack and a protective bottom grid made of food-safe silicone. The grid will cover most any sink, and it's handy for stacking dishes or soaking utensils. The sink has a 1-3/8-inch hole for drainage, so you will need a 1-3/8-inch drain adapter (not included).

The Dekor Sinks 89499Q Westwood Composite Granite Double Bowl Kitchen Sink with Four Holes is a well-built and durable sink, with a non-porous surface that's easy to clean. However, like most composite sinks, it has a relatively shallow depth, so it may not be suitable for large pots and dishes. The sink has a four-hole faucet mounting pattern, though, so you can easily add a separate faucet sprayer. The sink has a good-looking black finish and is moderately easy to install. However, it's not as easy to install as some of the others we tested, such as Kraus, because it's more fussy than most. First, the sink's fiberglass backing is adhered to the sink, so you can't simply unscrew it. Second, the sink has an epoxy coating that's receptive to water, so if you're working with wet hands, you'll have to wipe them off to prevent the transfer of water from the sink to the epoxy. Also, the sink is heavy, so you'll want to have an extra hand or two around during installation.
