Best Single Vs Double Bowl Kitchen Sinks Reviewed

Single/Double Basin Sinks Compared

Single vs Double Bowl Kitchen Sinks Explained

A single bowl sink is just as it sounds - it only has one basin rather than two. A single bowl has several advantages, the main one being that it saves on precious counter space. Even if you have plenty of counter space, though, you might opt for a large single bowl sink. If you cook with a lot of large pots and pans and wash them by hand, a large single bowl sink will make your life easier.

The main disadvantage to this type of sink is that you can’t separate your clean and dirty dishes and it is much less versatile. Your heavy metal-ware will be combined in the same basin as more delicate glassware, like wine glasses or fine china, increasing the chance of breakage. But if you are limited on space, a single bowl sink might be your only choice.

A double bowl sink has two basins that are separated by a metal wall, sometimes with equally-sized bowls, but more often with one larger and one smaller sink area. Double bowl sinks are ideal if you aren’t short on counter space and enjoy washing dishes by hand. If you have or want a top-rated garbage disposal, installing a double bowl sink is necessary. However, washing large pots and pans can be difficult in a tub like this.

Choosing a Quality Kitchen Sink

Deciding on a single vs. double bowl sink for your kitchen takes some careful thought and consideration. You need to think about your cooking and dishwashing habits, as well as budget and available space. Here are all of the factors to help with choosing a quality kitchen sink.

Sink Size/Depth vs Kitchen Counter/Cabinet Space

Sink Material & Finish

Just as kitchen sinks can vary in size and configuration, they can be made from a variety of materials. Sinks made from stainless steel are the most common, making up about 70% of all sinks on the market. JustSinks says that “for more than half a century, stainless steel sinks have been used in industrial, architectural, culinary, and residential applications…”

The main reason for the popularity of this material is that "stainless steel is a low-carbon steel which contains chromium at 10.5% or more by weight. The addition of this chromium gives the steel it's unique stainless, corrosion-resisting and enhanced mechanical properties." Stainless steel sinks come in a variety of finishes, including mirror, brush, matte, and satin finishes.

However, stainless steel is not the only material used in sinks these days. Granite/quartz composite sinks are another option, as are copper and fireclay kitchen sinks. Sinks made out of cast iron are also popular, but all of these materials are much pricier than more commonly used stainless steel.

Durability

Something used as frequently as the kitchen sink needs to be durable and withstand the test of time. In terms of strength, stainless steel is generally ranked reasonably high compared to other materials.

It does well against stains and heat, but remember that it can still become scratched and dented over time if you aren’t careful. If durability is your main concern, you might also think about installing a granite composite sink, which some manufacturers claim to be the most durable and long-lasting material of all.

Ruvati, a leading sink manufacturer, says that if you do opt for stainless steel, the durability is measured by gauge. The more durable stainless steel has a lower gauge (either 16 or 18). Thinner, less durable stainless steel has a higher gauge (around 22). Stainless steel sinks with a gauge of 16-18 are great for both residential and commercial use since they stand up well to wear and tear.

Installation

There are two main types of installation procedures for kitchen sinks: undermount and top mount (or drop in). Top mount sinks are more traditional and "drop-in" from above to rest on the countertop. Undermount sinks, on the other hand, are mounted from below and sit beneath the surface of the countertop.

Undermount sinks are growing in popularity since they look sleek and create a more continuous flow across the countertop. The countertop area surrounding the sink is much easier to clean since there is no sink ridge or lip where food and debris can collect. However, under mount sinks are more challenging to install and tend to be more costly.

Design

Price

A double bowl sink costs more on average than a single bowl since more material is used and they tend to be larger. However, price is also dependent on the sink's contents and finish. Stainless steel is one of the most budget-friendly options; composite granite and cast iron will have a higher price tag.

Price also varies depending on the brand; well-known brands like Moen and Kohler tend to be pricier than unheard of brands since they provide high-quality products. On average, a 33-inch single bowl sink made from stainless steel costs about $220. A double bowl sink of the same size and material will cost about $300.

Warranty

The sink is one of the most frequently used features in any kitchen. A leaky or cracked kitchen sink can be a huge problem, but luckily most sinks come with a limited lifetime warranty. Always check to see which parts and malfunctions are covered; even if you have a lifetime warranty, it is limited to specific components and defects.

1. Kraus KHU100-30 

The Kraus 30-inch single bowl sink is my #1 choice, and a lot of reviewers also agree. One of the top features of this stainless steel sink is that you can choose from a variety of sizes, anywhere from 14 to 30 inches. No matter which size you want, each one features under mount installation that looks sleek in any kitchen.

The sink bottom is engineered for superior drainage that prevents standing water with its gently sloping surface. The stainless steel is finished with a protective coating that not only protects your dishware and the actual sink but also keeps condensation from building up on the lower kitchen cabinets.

This sink utilizes 16-gauge stainless steel that is indestructible; like all stainless steel it is resistant to corrosion, but its low gauge also makes it dent-resistant. In addition to durability, it's satin finish makes it extremely easy to maintain, making it ideal for both commercial and residential use. This finish pairs well with any stainless steel appliances, fitting well into the design of any kitchen.

The extra-deep sink bowl will accommodate your large pots and pan with no trouble at all. You’ll be able to wash these dishes as quietly as possible since the Kraus is equipped with a NoiseDefend soundproofing technology. Along with a limited lifetime warranty, you’ll be given a few free accessories, like a stainless steel sink protector, a 3-piece gasket strainer set, and a Kraus kitchen towel.

2. Ruvati Drop-in Topmount

For easy installation, you'll want a drop-in sink like the Ruvati single bowl. Like most single bowl sinks, you can choose between a variety of sizes, but the largest and most popular is the 33" by 22" basin. The 16-gauge stainless steel is resistant to stains, heat, corrosion, and dents. Even so, it is still a good idea to use the sink bottom rinse guard that is included with your purchase.

The Ruvati comes in a brushed finish that some people feel hides scratches better than a satin finish. The soundGUARD coating and rubber padding on the underside of the sink effectively minimize noise and helps to reduce condensation for cabinet protection.

There is, however, some negative feedback regarding the slope of the sink bottom. The minimal amount of sloping means that not all food particles will go down the drain on their own; you’ll have to use the faucet sprayer to guide food waste down the drain.

3. ZUHNE Prato 

Farmhouse style sinks are gaining popularity by the day, and one of the top farmhouse models is the Zuhne Prato single bowl sink. This sink has more 5 star reviews than any other single basin farmer sink on the market right now. A significant reason for this is the industrial strength 16-gauge stainless steel that is durable as well as easy to clean.

The top feedback relates to the overall design of this sink; it looks good in any kitchen and the satin finish matches with all stainless steel appliances. Both InSinkErator and WasteKing garbage disposals are muted with the Zuhne’s noise control capabilities. This insulation also protects from condensation from harming kitchen cabinetry.

The sink’s base has a perfect slope that leads food particles and debris to the 3.5” rear drain faster than the average sink. The only negativity expressed about this sink is that the farmhouse under-mount style makes it more challenging to install and hiring a plumber for installing this type of sink costs more on average. But overall, this Zuhne is appealing to the eye and worth the extra installation cost.

4. Kraus Standart PRO

The second Kraus model to make this list is the Standart PRO 32-inch Undermount Single Bowl. Unlike the first Kraus I mentioned, this one comes with the faucet and soap dispenser included, although you can also purchase the sink alone. The sink comes in stainless steel no matter what, but you can choose from a variety of faucet finishes, including matte black, chrome, and a combination of both.

The single large basin is perfect for washing dishes, especially since it is 32 inches in length and 19 inches wide. You'll need a bit of extra cabinet space - 36 inches - which is more than the average 33 inches that are typically required. The commercial-grade faucet makes washing dishes by hand more comfortable than ever. Constructed out of 16-gauge steel, this sink should last at least two decades, and reviewers say that it is durable against denting, heat, and corrosion.

The size is great for some, but a few reviewers have had some negative feedback on it; since it requires more cabinet space (36 inches instead of 33) mounting a garbage disposal can be more difficult with this sink.  Another comment is that it could have a slightly steeper slope for better drainage. But if you want a sizeable, sturdy tub that looks nice in any kitchen, this Kraus is a great choice.

5. Ruvati Low-Divide 50/50

Single bowl sinks are popular for the space they provide, but you can’t compare it with a double bowl in terms of versatility. This is especially true of the Ruvati 32-inch sink with equally-sized double basins. Like the first Ruvati I reviewed, this one is composed of 16-gauge stainless steel with soundGUARD padding and undercoating to protect the lower cabinet space.

Unlike other double bowl systems, this one has a unique divider that is 3 inches lower than the top of the sink; this extra clearance makes it easier to wash dishes, exceptionally large pots/pans and cookie sheets. This is the perfect option for anyone without a dishwasher or prefers washing dishes by hand. 

Although the Ruvati does not come with a faucet and soap dispenser, the manufacturer provides you with two metal rinse grids (one for each basin), two basket strainers, and all of the necessary installation materials. The under-mounting installation makes cleaning the surrounding counter area more effortless than ever since there is no sink lip for food or debris to become stuck.

The Ruvati 50/50 double bowl has an impressive 4.8 stars out of nearly 300 reviews on Amazon. There have been a few comments about how water spots appear on the stainless steel, and it can be challenging to clean, but the overall consensus is exceptionally favorable. Some reviewers have also commented on the limited depth of the sink basins since they are only 8.5 inches rather than the regular 10.

6. ZUHNE Turin 

Anyone wanting a unique farmhouse sink with two basins should consider the Zuhne Turin 33” Apron Front model. Unlike the Ruvati double bowl sink, the two bowls are not equal in size - it has a divider creating a 60/40 split. The larger basin offers plenty of space for washing large dishes and cookware.

Made from 16-gauge brushed stainless steel, the standard size for this model is 33 inches, but you can opt for the larger 36-inch model for even more sink space. Both sizes feature the same industrial strength brushed steel, evolutionary noise control features, quick draining with sloped base channels, and a lifetime warranty with free returns.

Choosing the right farmhouse sink can be challenging, mainly since more manufacturers focusing on the farmhouse design. All in all, the Zuhne Turin 33 is a top contender, especially if you want a high-end look for a low-end cost. Just be sure to use the proper cleaning products - a couple of reviewers have complained about light rusting over time.

7. Kraus Standart PRO 60/40

Another Kraus product to make the cut, the Standart PRO 33-inch sink is my top choice for undermount double bowl sinks. You can purchase it with or without the faucet and soap dispenser, but no matter what you choose you can rest easy knowing that the stainless steel is indestructible.

The commercial-grade satin finish doesn't just look good, but it is also resistant to rust and corrosion - not to mention it is straightforward to clean. Like all Kraus models, this one features NoiseDefend technology and utilizes pads to cover 80% of the sink's underside. This lessens garbage disposal noise and provides the cabinets with protection.

As far as cons go, some reviewers claim that the metal racks included to protect the base of each basin aren’t high in quality and they can be a pain to clean. They do offer added protection, though, so it is still recommended that you use them or at least purchase something similar.

The 60/40 split system is a top-seller since having one larger bowl is ideal for washing pots and pans. If you are limited on space, though, this sink is probably not the one for you. It takes up a lot of counter space, and it requires more cabinet room than the average sink, 36 inches instead of 33. But if the area is not an issue, this sink will fit well within any clean contemporary kitchen.

8. Kraus KGD-433B 50/50 Granite

Of course, I had to end this list with another Kraus model. If you want a double bowl but don't need one to be larger than the other, the 50/50 split is perfect. This kitchen sink is the only one I have included that is not composed of stainless steel. Instead, it is made from black onyx granite composite made of 80% quartz.

In addition to the unique material, there is another feature that makes this sink stand out from the rest on this list. It can be installed using two different methods, either undermount or top mount. This makes it compatible with a range of countertop configurations and materials. As long as you aren’t limited on space, this can be installed within any countertop.

This model is sound-absorbing since the sturdy stone-like material absorbs vibration and minimizes noise when the sink is in use, or the disposal is running. The composite granite is easy to clean since it is naturally hygienic non-porous material that is highly resistant to dirt and grime. Wipe the surface with a non-abrasive cleaning agent to keep this sink looking shiny and new.

The only downfall is that the dark stonelike material might not fit into every kitchen design, especially if every other appliance in your kitchen is stainless steel. The depth of each basin is also a bit shallower - 9.5 inches - rather than the average 10 inches. However, the width is even more substantial than the average at 22 inches.

Various Kitchen Sink Installations

Hiring a professional plumber to install your new kitchen sink is a good idea unless you have experience of your own. The steps involved depend on whether it is a single vs. double bowl sink as well as the mounting type (top mount, undermount, or farmhouse). Since there are two basins within a double bowl sink, these are more difficult to install.

Lowe’s provides step-by-step instructions on removing the existing sink and installing your new one. They offer a useful tip that a lot of people don't think to do - take a photo of the plumbing assembly before you start so that you can refer back to it as you install the new sink. Follow these steps according to the type of sink you have and its mounting type.

Top Mount

For any top mount sink, the first step is to use the cut-out template provided to cut a suitably sized hole in your countertop. This can be done using a jigsaw or keyhole saw. If you already have a hole from your previous sink, you might need to adjust the size. Ideally, you will find a sink replacement of the same size, but this is not always the case.

Once the hole is cut, apply the provided mounting clips to the underside of the sink rim. Next, you'll follow the instruction manual to prepare the sink drain pipe and strainer bottom. Once these steps are completed, apply either plumber's putty or caulk along the underside of the sink rim. The sink can then be carefully lifted and lowered into place, dropping into the countertop from above.

Undermount

The main difference with installing an undermount sink is that it needs to be mounted while the countertop is not in place. When the countertop is removed or yet to be installed, the supports can be set, and the sink can be placed on the frame.

You'll need to apply a generous amount of caulk around the top of the sink flange. From there the countertop slabs can be set in place, essentially sandwiching the sink between the countertop and the frame of the cabinet.

Farmhouse

Installing a farmhouse sink (also known as apron front) tends to be a bit trickier. Farmhouse sinks often require custom made sink base cabinets since the front of the cabinet is cut out to expose the sink front. You'll also need to remove the surrounding countertops as you would in an under-mounted sink.

Once the cabinetry has been appropriately cut, you can use the provided template to make adjustments to the countertop. After the countertop has been cut accordingly, it is time to set the farmhouse sink in place. Apply sealant between the sink and cabinet wherever necessary. Before replacing the countertop, apply silicone adhesive around the top edge of the sink where the countertop will lay.

Installing Double Bowl Sinks

Installing a double bowl system is more challenging since your kitchen sink will technically have two drain systems. The procedures for setting the sink into place are similar to what I’ve mentioned above, but for properly installing the drainage you can follow these steps.

Care and Maintenance Of Your Kitchen Sinks

No matter if you choose a single or double basin sink, the way you care for it depends on its material and finish. Caring for a stainless steel sink involves different steps than maintaining a cast iron sink. In general though, here are a few helpful tips to follow:

Tips On Kitchen Sink Stain Removal

The best way to keep your kitchen sink clean is to take preventative measures. You can prevent food from hardening on your sink and forming a stain by soaking your sink in hot water after washing dishes. If food has already hardened, gently scrub the area with a sponge or scrub brush after it has been soaking.

HouzerSink says that “to remove hard water mineral deposits or coffee stains, fill the sink about a quarter of the way with water and vinegar or phosphoric acid. Follow with cleansing powder then rinse and dry." For hard-to-clean stains on stainless steel sinks, three methods have proven to be effective:

After scrubbing with one of these mixtures, follow up by rinsing with hot water and dry with a microfiber cloth to prevent water marks from forming.

People also Ask (FAQs)

Which is better of the two, a single bowl or a double bowl kitchen sink?

There is no definitive answer to this since it depends on your available kitchen space as well as your cooking habits. Remodelista says that "there are several factors to consider, including how much space you have, how many people use your kitchen at the same time, how often you entertain, and how you tend to clean up." It is essential to consider all of these things in addition to cost, warranty, design, and durability.

How long do kitchen sinks last? How durable are they?

Your kitchen sink can last anywhere from 15 to 30 years. This depends on the sink material and its durability, but also keep in mind that no matter the sink material, proper maintenance will make your sink last longer.

Does stainless steel kitchen sink last longer than others?

Stainless steel is one of the most durable options, but some say that porcelain lasts longer. Porcelain sinks have a core that is made with cast iron, which is an extremely durable material. However, if you properly care for your stainless steel sink, it can last just as long as porcelain or any other material.

What does Limited Lifetime Warranty on kitchen sinks mean?

A kitchen sink with a limited lifetime warranty means that the manufacturer is obligated to replace sink parts that become defective throughout the life of the product. However, you always need to read the warranty details since coverage is limited to specific components, not all of them. If something breaks because of misuse by the consumer, that also will not be covered.

Does gauge matter when choosing stainless steel single or double bowl kitchen sinks?

According to SFGate, you can “get the most longevity from a stainless steel sink by installing one with a low gauge number. The lower the gauge, the thicker the steel and the longer it will last.” So yes, the gauge of stainless steel does matter, and you should opt for a lower gauge value.

How much does it cost to install a farmhouse single or double bowl kitchen sink?

On average, the cost of installing a double bowl sink is more than installing one with a single basin. Installing a single farmhouse bowl is the most complex since the front panel drops over the edge of the countertop, so the cost of installing this is the most expensive at an average of $240.

Hiring a plumber to install an undermount double bowl is just a bit cheaper than farmhouse installation, about $230. The cost of installing a top mount single bowl sink is the lowest - about $195 - since it involves the most natural installation procedure. 

Conclusion

Of course, you need to consider whether a single bowl or double bowl is the right choice for you, but if you are leaning towards a single bowl or can't decide between the two, you can't go wrong with the Kraus KKU100-30 model reviewed first on the list.

Its undermount installation provides a seamless transition from sink to the countertop that looks crisp, clean, and modernizes any kitchen. Kraus sinks are often described as indestructible since they are constructed with high-quality 16 gauge steel and the satin finish makes cleaning more effortless than ever. Any kitchen upgrade would benefit from adding this sink into the mix.
