Drop-in kitchen sinks are the easiest type of sinks to install. All you need is a properly-sized cutout in the counter (it doesn’t have to be perfect) and some sealant.
Drop-in kitchen sinks can be installed on most kinds of countertop materials. Because their rim sits on top of the counter, debris can’t be easily swept into the sink, and water and grime may get trapped between the rim and the countertop when poorly installed. That said, plenty of drop-in sinks – especially stainless steel ones – have thin, almost seamless rims. And their simplicity – and low costs – makes them an attractive choice.
Ruvati RVH8001 (33″, 16 Gauge Stainless Steel, Single Bowl)
The Ruvati 33” drop-in kitchen sink is made out of 16 gauge stainless steel. Gauge refers to the thickness of the steel. The lower the gauge number the stronger and higher quality the sink. When it comes to kitchen sinks, an 18 gauge is the bare minimum we would recommend choosing. An 18 gauge piece of steel is 1.2 mm thick and a 16 gauge piece of steel is 1.5 mm thick. What makes this Ruvati one of the best drop-in sinks is the quality of steel. It is a solidly-constructed, beautiful stainless steel drop-in sink.
This Ruvati has the dimensions of a standard kitchen sink, which is why it works for most kitchens. It is 33” from left to right, 22” from front to back, and roughly 10” deep. The design allows the sink to maximize functional space. It really feels like the bowl is very large and that you have plenty of space to work with. This particular sink has a single bowl that is perfect for holding large pots and pans.
The look of the sink is modern and the stainless steel material is easy to clean. It comes with four pre-drilled holes for faucet and soap dispenser. But if you don’t plan on using all of them the sink comes with 3 removable decorative stainless steel plugs. There is limited lifetime warranty with this sink. Overall, this is a heavy-duty, beautiful, and functional drop-in sink.
Primart (33”, 16 Gauge Stainless Steel, Double Bowl)
For those who are looking for a sink similar to the Ruvati but with double bowls, the Primart 33” drop-in kitchen sink will fit the bill. It is made out of the same 304 grade stainless steel at 16 gauge thickness. The dimensions are the same and that of a standard kitchen sink. It measures 33” from left to right, 22” from front to back, and 10” deep. For comparison purposes the bowls feel just as large and as deep as the Ruvati, but they are divided into two. The bowls are divided equally (at a 50/50 configuration).
The sink has two pre-drilled holes – one for the faucet and one for the soap dispenser. It comes with two plugs if you plan to cover the holes. Just like the Ruvati it comes with limited lifetime warranty.
Mowa HKN3322 (33”, 16 Gauge Stainless Steel, Single Bowl)
The Mowa HKN3322 drop-in sink mimics the Ruvati in many ways. They are both made out of the same kind of stainless steel, they have the same dimensions, and they both have a single bowl. There is one major difference however. The Mowa HKN3322 has an ultra flat rim that installs almost seamlessly on the countertop. With this sink it is much easier to sweep any debris into the sink. The other difference is that this model comes with 2 pre-drilled holes instead of four that the Ruvati has. So if you want something that sits almost flush with your countertop, the Mowa is a great sink.
Blanco Diamond (33”, Composite, Double Bowl)
Blanco has been making kitchen sinks for over 80 years. As a German company, they have a tendency of making products by balancing function with style. The Blanco Diamond double bowl drop-in composite sink is a fine looking sink that oozes quality. It is made of 80 percent solid granite – meaning it has a high granite content that lends to the sink’s durability. Its dimensions are standard: 33” by 22” by 9.5”.
As a composite sink, it comes in a variety of colors with names like “café brown”, “truffle”, “biscotti”, “cinder”, and “anthracite”. You can find this sink with equal or offset double bowls, where the smaller bowl has a slightly smaller depth of 8 inches. They all have a single pre-drilled hole for the faucet. This drop-in sink would appeal to those looking for some accent and color in the kitchen.
Kraus KGD-433B (33”, Composite, Double Bowl)
The Kraus KGD-433B drop-in sink is a composite sink with a clean rectangular rim. It is made out of 80 percent granite so the quality is on par with the Blanco Diamond. The appeal of the Blanco Diamond is all about the curves, whereas the appeal for this Kraus is all about the straight lines complemented by rounded corners. This allows it to have extra large bowls.
The dimensions for this sink are 33” by 22” by 9.5”. The bowls are split 50/50. And just like the Blanco Diamond it has a single pre-drilled hole for the faucet. The sink comes in Black Onyx and the divider has a metal-colored piece for contrast.
