If you're planning a kitchen remodel in NJ, the single bowl vs double bowl sink decision might seem minor compared to cabinets and countertops. But your sink is the most-used fixture in the kitchen -- you interact with it dozens of times a day. Getting it right matters more than most people realize.
The kitchen sink market has shifted dramatically in the past decade. Double bowl sinks used to be the default for every kitchen. Now, single bowl sinks outsell double bowls in most categories. But that doesn't mean the double bowl is obsolete -- it still has genuine advantages for certain cooking styles.
In this guide, we break down every factor that matters -- usable space, multitasking, cost, materials, installation, and which works better with modern kitchen workflows. As a kitchen remodeling company based in Ewing Township, NJ, we've installed thousands of sinks in both configurations over 25+ years. These recommendations come from watching real families use their kitchens, not from product spec sheets.
Quick Answer: Single vs Double Bowl
Choose a single bowl sink if you have a dishwasher, cook with large pots and pans, want maximum usable sink space, or have a smaller kitchen. Single bowl sinks are the modern default and the better choice for most NJ kitchens.
Choose a double bowl sink if you hand-wash most dishes, frequently multitask at the sink (washing vegetables while soaking pots), don't have a dishwasher, or simply prefer the divided layout from habit.
Bottom line: About 70% of our NJ kitchen remodel clients now choose single bowl sinks. The shift is driven by dishwashers (which eliminate the wash/rinse workflow) and larger cookware that simply doesn't fit in a divided sink. But if you hand-wash everything, the double bowl still earns its place.
Side-by-Side Comparison Table
Here's the full single bowl vs double bowl comparison at a glance. We dig into each category in detail below.
| Criteria | Single Bowl | Double Bowl | Winner |
|---|---|---|---|
| Cost (sink + install in NJ) | $250 -- $1,200 | $250 -- $1,400 | Single (slightly less) |
| Usable space | One large uninterrupted basin; fits sheet pans, stock pots | Two smaller basins; large items don't fit in either | Single Bowl |
| Washing large items | Fits baking sheets, stock pots, roasting pans flat | Large items must be angled or propped up | Single Bowl |
| Multitasking | One task at a time; accessories can help | Wash in one bowl, rinse/prep in the other simultaneously | Double Bowl |
| Installation | One drain, simpler plumbing, less labor | Two drains, more plumbing connections, slightly more labor | Single (simpler) |
| Countertop compatibility | Fits 30"+ base cabinets; works with any countertop | Needs 33"+ base cabinet; works with any countertop | Single (more flexible) |
| Dishwasher impact | Perfect complement; large basin for hand-wash overflow | Divided layout less useful when dishwasher handles dishes | Single (with dishwasher) |
| Popular sizes | 28", 30", 32", 33" | 33", 36" | Tie |
| NJ market preference | Trending up strongly; 70% of our remodel installs | Still popular in traditional kitchens; 30% of installs | Single Bowl (trending) |
| Best for | Dishwasher owners, large cookware, small kitchens, modern style | Hand-washers, multitaskers, traditional kitchens, no dishwasher | Depends on kitchen habits |
What Is a Single Bowl Sink?
A single bowl kitchen sink is exactly what it sounds like: one large, uninterrupted basin with a single drain. No divider, no second compartment. Just one open space for washing, rinsing, and prepping.
Single bowl sinks have been trending upward for the past decade, and in 2026 they've become the clear market leader. The shift happened for a simple reason: most households now have dishwashers. The traditional wash-and-rinse workflow that made double bowls essential has largely disappeared from daily life.
The biggest practical advantage of a single bowl is usable space. A 30-inch single bowl gives you one continuous basin roughly 28 inches wide -- large enough to lay a half-sheet baking pan flat, submerge a stock pot, or wash a large cutting board without propping it at an angle. Try doing that in one side of a double bowl sink.
Single bowl sinks also pair beautifully with modern kitchen aesthetics. The clean, uncluttered look of one basin works well with undermount installation, waterfall-edge countertops, and minimalist design trends that dominate the NJ market.
What Is a Double Bowl Sink?
A double bowl sink has two separate basins divided by a center wall, each with its own drain. The bowls can be equal in size (50/50 split) or unequal (60/40 or 70/30 split, with one larger basin and one smaller).
Double bowl sinks were the kitchen standard for decades -- and for good reason. Before dishwashers were common, the two-basin design allowed you to fill one side with soapy water for washing and the other with clean water for rinsing. This was the most efficient way to hand-wash a full sink of dishes.
The double bowl still has legitimate advantages. The divided layout lets you do two things at once: soak dirty pots on one side while rinsing vegetables on the other, or keep one basin clean for food prep while the other handles dirty dishes. This natural separation is genuinely useful for people who cook frequently and manage multiple tasks at the sink.
The 60/40 split has become more popular than the traditional 50/50 because it gives you one basin large enough for most pots and pans while still providing a dedicated second compartment. If you're leaning toward a double bowl, the 60/40 is almost always the smarter choice.
Cost in NJ: Single vs Double Bowl
The sink itself is rarely the biggest expense in a kitchen remodel, but here's how the pricing breaks down in New Jersey:
| Material | Single Bowl (sink only) | Double Bowl (sink only) |
|---|---|---|
| Stainless steel | $100 -- $400 | $120 -- $500 |
| Composite granite | $250 -- $600 | $300 -- $700 |
| Fireclay | $400 -- $1,000 | $500 -- $1,200 |
| Cast iron (enameled) | $300 -- $800 | $350 -- $900 |
NJ Installation Costs
Installation labor in New Jersey runs $150 to $400 for a sink replacement in an existing countertop, or $200 to $600 if new countertop cutout work is needed. Single bowl sinks are slightly cheaper to install because they have one drain connection and simpler plumbing. Double bowl sinks require two drains plumbed into a shared waste line, which adds $50--$150 in labor and fittings.
Mercer County pricing note: The total cost of a mid-range kitchen sink replacement (sink + installation + new faucet) in Mercer County runs $600 to $1,500. This assumes an existing countertop cutout that fits the new sink or requires minor modification. If the sink is part of a full kitchen remodel with new countertops, the cutout is included in the countertop fabrication cost.
Usable Space: Why Single Bowl Wins for Large Items
This is the category that has driven the single bowl's rise to dominance, and it's simple math.
A 33-inch double bowl sink (the most common size) divides into two basins of roughly 14 to 15 inches each after accounting for the center divider. That means each bowl is narrower than a standard half-sheet baking pan (13x18 inches). It's narrower than most stock pots. It's barely wider than a dinner plate.
A 30-inch single bowl sink gives you one continuous basin roughly 28 inches wide. That fits a half-sheet baking pan lying flat, a large roasting pan, a stock pot with room to scrub around it, or a bulky cutting board without any awkward angling.
Here's what fits (and doesn't) in each:
| Item | Single Bowl (30") | Double Bowl (33", one side) |
|---|---|---|
| Half-sheet baking pan | Fits flat | Must angle or prop |
| Large stock pot (12 qt+) | Fits with scrub room | Tight fit, hard to scrub around |
| Roasting pan / dutch oven | Fits easily | Barely fits or doesn't fit |
| Large cutting board | Fits flat for rinsing | Won't fit in either bowl |
| Baby bath / pet washing | Plenty of room | Too narrow for comfort |
Multitasking: Why Double Bowl Has an Edge
The double bowl sink's strongest advantage is built-in task separation. Having two distinct basins means you can naturally run two parallel workflows:
- Soak dirty pots on one side while rinsing fresh vegetables on the other -- without dirty water touching your food.
- Keep one basin empty and clean for food prep while the other collects used dishes throughout the meal.
- Defrost meat in cold water on one side while the other side remains available for normal use.
- Run the garbage disposal on one side while using the other basin without interruption.
This workflow separation is genuinely valuable for people who cook from scratch daily. If you're prepping a full Thanksgiving dinner or making pasta from scratch while simultaneously washing produce, the double bowl makes life easier.
Can single bowl sinks multitask? Yes, with accessories. A sink-mounted colander, cutting board, or drying rack that sits across the rim can create separate work zones within a single basin. Several modern single-bowl sinks (like the Kraus Kore Workstation series) are designed specifically for this "workstation" approach. But it's an add-on solution vs the double bowl's built-in separation.
The Dishwasher Factor
This is the single biggest factor driving the shift toward single bowl sinks: if you have a dishwasher, you don't need the double bowl wash/rinse workflow anymore.
Think about it: the double bowl sink was designed for an era when every dish was washed by hand. One basin held hot soapy water. The other held clean rinse water. Dishes went from left to right: dirty, wash, rinse, drying rack. The two-basin design was a washing system.
With a dishwasher, that system is obsolete for everyday dishes. You scrape, rinse, and load. The only things you hand-wash are items too large or delicate for the dishwasher: large pots, cast iron, chef's knives, and specialty items. And those items wash better in a single large basin where you have room to maneuver.
No dishwasher? If your kitchen doesn't have a dishwasher (or you prefer not to use one), the double bowl retains its original advantage. The wash/rinse workflow is genuinely more efficient with two basins. This is especially relevant in older NJ apartments, townhomes, and galley kitchens where a dishwasher was never installed.
Sink Materials Compared
The single vs double debate applies to every material. Here are the four main kitchen sink materials and how they perform:
Stainless Steel
The most popular kitchen sink material overall. Lightweight, affordable, and nearly indestructible. Available in both single and double bowl configurations in every size. Look for 16-gauge or 18-gauge thickness for durability -- avoid 20-gauge or thinner, which dents easily and sounds hollow. Stainless steel shows water spots and scratches over time but never chips or cracks. Best for budget-friendly kitchen remodels. $100 -- $500 range.
Composite Granite
Made from crushed granite mixed with acrylic resin (similar to quartz countertops). Extremely durable, scratch-resistant, stain-resistant, and heat-resistant up to 535°F. Available in colors that match popular countertop materials. Brands like Blanco Silgranit, Kraus Quarza, and Elkay Quartz Classic lead the market. Composite granite is our most-recommended sink material for NJ kitchen remodels because it combines the durability of stone with modern aesthetics. $250 -- $700 range.
Fireclay
Ceramic clay fired at extremely high temperatures (1,800°F+) to create a glass-hard surface. Fireclay is the traditional material for farmhouse (apron-front) sinks. Virtually indestructible, stain-proof, and scratch-resistant. Available primarily in white and off-white. Heavy (60--100 lbs), so the base cabinet may need reinforcement. Most fireclay sinks are single bowl due to the manufacturing process, though double bowl versions exist at premium prices. $400 -- $1,200 range.
Cast Iron (Enameled)
Solid cast iron coated with a thick porcelain enamel. Extremely durable, heavy (75--120 lbs), and available in a wide range of colors. The enamel surface is easy to clean and resists stains, but it can chip if hit with heavy objects -- and chips are nearly impossible to repair invisibly. Kohler is the dominant brand in this category. Available in both single and double bowl. $300 -- $900 range.
Undermount vs Drop-In for Each Type
How you mount the sink matters as much as the bowl configuration. For a deeper comparison, see our undermount vs drop-in sink guide.
Undermount
The sink mounts beneath the countertop, leaving a clean, seamless edge. Crumbs and water wipe directly from the counter into the sink with no rim to catch debris. This is the preferred installation for quartz, granite, and solid surface countertops. Undermount works with both single and double bowl sinks, and it's the standard choice for NJ kitchen remodels in 2026. The clean look pairs especially well with single bowl sinks for a minimalist aesthetic.
Drop-In (Top-Mount)
The sink sits on top of the counter with a visible rim. Easier and cheaper to install -- the sink drops into a simple cutout and the rim supports its weight. Drop-in is the only option for laminate countertops since laminate cannot support the weight of an undermount sink from below. If you have granite or quartz countertops, we strongly recommend undermount instead.
The main drawback of drop-in is the rim. The raised edge collects crumbs, grime, and water that you can't simply sweep into the sink. You have to clean around and under the rim regularly, which is an ongoing annoyance that undermount completely eliminates.
Popular Sizes
Kitchen sink size is determined by your base cabinet width. The sink must be smaller than the cabinet to allow for mounting clearance. Here are the most common sizes we install in NJ:
| Base Cabinet Width | Single Bowl Options | Double Bowl Options | Our Recommendation |
|---|---|---|---|
| 30" cabinet | 28" single bowl | Not recommended (bowls too small) | Single bowl |
| 33" cabinet | 30" -- 31" single bowl | 33" double bowl (50/50 or 60/40) | Single bowl (unless hand-washing) |
| 36" cabinet | 32" -- 33" single bowl | 36" double bowl (60/40 ideal) | Either works well at this size |
Depth matters too. Standard kitchen sinks are 8 to 10 inches deep. We recommend 9 to 10 inches for the best balance of capacity and comfort. Shallower sinks (8 inches) splash more. Extra-deep sinks (11--12 inches) require more bending, which causes back strain during extended use. The sweet spot for most people is 9.5 inches.

From Our Experience
In our 25+ years of kitchen remodeling in NJ, here's what we've learned about sinks that you won't find in a product listing:
About 70% of our remodel clients now choose single bowl -- and that number keeps climbing. Five years ago it was roughly 50/50. The shift is real and accelerating. Clients who switch from double to single almost universally say "I should have done this sooner" within the first week of using the new sink.
The clients who stick with double bowl are serious cooks without dishwashers. We see this most in our NJ clients who cook large family meals from scratch nightly -- Indian, Italian, Caribbean, and Korean cooking families in particular. These households produce a lot of dishes, often don't use a dishwasher for cultural or preference reasons, and genuinely use both basins every single day. For them, the double bowl is the right answer.
Composite granite has replaced stainless steel as our top-recommended material. It resists scratches, doesn't show water spots, absorbs sound better than stainless, and comes in colors that coordinate with quartz countertops. The $150--$300 premium over stainless is worth it for a fixture you'll use for 15--20 years. Browse our sink collection to see options.
The 60/40 double bowl is the compromise that satisfies almost nobody. In theory, the 60/40 gives you a "big enough" main basin and a useful second compartment. In practice, the large side is still too small for sheet pans, and the small side is too small for soaking pots. If you want multitasking, go 50/50. If you want usable space, go single bowl. The 60/40 is a compromise that undersells both advantages.
Always see the sink installed in a mock countertop before committing. Sink proportions look different in a showroom display vs in your actual kitchen. We keep mounted demo sinks in our Ewing Township showroom so you can stand at a realistic counter height and test the basin depth, width, and access with real pots and pans.
Decision Guide: Which Should You Choose?
Answer these four questions to find your best match:
1. Do you have a dishwasher?
Yes: Single bowl is the better choice. The dishwasher handles everyday dishes; you need a large basin for the oversized items that don't fit in the machine. No: Double bowl retains its classic wash/rinse advantage. Consider a 50/50 split for the most efficient hand-washing workflow.
2. What size cookware do you use?
Large stock pots, baking sheets, roasting pans: Single bowl -- these items need an uninterrupted basin to wash comfortably. Standard pots, pans, plates: Either configuration works. Choose based on other factors.
3. How big is your kitchen (and base cabinet)?
30-inch base cabinet or smaller: Single bowl is the only sensible choice -- a double bowl would give you two unusably small basins. 33-inch or larger: Both configurations work. You have enough room for a double bowl with reasonably sized basins if that's your preference.
4. Do you multitask at the sink?
Frequently run two tasks simultaneously: Double bowl gives you built-in separation. Soaking on one side while prepping on the other is genuinely useful. Mostly single-task use: Single bowl gives you maximum space for each task as it comes.
Frequently Asked Questions
Is a single or double bowl sink better for a small kitchen?
A single bowl sink is almost always better for a small kitchen. It maximizes usable sink space within a limited countertop footprint. A single 30-inch sink gives you one large uninterrupted basin, while a double 33-inch sink splits that into two small basins that can barely fit a baking sheet. In compact NJ kitchens, every inch of countertop and sink space matters.
Do I need a double bowl sink if I have a dishwasher?
No. The original reason for double bowl sinks was to have one basin for washing and one for rinsing dishes by hand. If you have a dishwasher that handles most of your dishes, you lose the primary advantage of the double bowl. A single bowl gives you more room to hand-wash the occasional large pot or pan that doesn't fit in the dishwasher. About 70% of our NJ clients with dishwashers now choose single bowl sinks.
Can you wash large baking sheets in a double bowl sink?
Usually not. A standard double bowl sink divides the basin into two compartments of roughly 14 to 15 inches each. Most full-size baking sheets (18x26 inches or 13x18 inches half sheets) won't fit flat in either bowl. A 30 to 33-inch single bowl sink can easily accommodate large baking sheets, stock pots, and oversized cookware -- which is one of the biggest reasons the single bowl has become more popular.
Which kitchen sink material is most durable?
Fireclay and composite granite (like Blanco Silgranit or Kraus Quarza) are the most durable kitchen sink materials. Both resist scratches, stains, chips, and heat better than stainless steel. Fireclay can last 50+ years without showing wear. Cast iron with enamel is also extremely durable but can chip if heavy objects are dropped in it. Stainless steel is durable but shows scratches over time. For NJ kitchens, we most frequently recommend composite granite for its combination of durability, aesthetics, and value.
Is undermount or drop-in better for a kitchen sink?
Undermount is better for most NJ kitchen remodels. It mounts beneath the countertop, creating a clean seamless look and making it easy to wipe crumbs directly into the sink. Undermount sinks work with quartz, granite, and solid surface countertops. Drop-in (top-mount) sinks sit on top of the counter with a visible rim -- they're easier and cheaper to install but collect grime around the rim edge. Drop-in is the only option for laminate countertops since they can't support undermount cutouts.
What size single bowl sink should I get?
For most NJ kitchens, a 30-inch single bowl sink is the sweet spot -- large enough for big pots and baking sheets, but fits in standard 36-inch base cabinets. If you have a 33-inch or larger base cabinet, a 32 to 33-inch single bowl gives you even more room. For smaller kitchens with 30-inch base cabinets, a 28-inch single bowl works well. Depth should be 9 to 10 inches -- deep enough for large items but not so deep that you're constantly bending over.
Are single bowl sinks more expensive than double bowl?
Prices are roughly comparable for the same material and brand. A quality stainless steel single bowl runs $150 to $400, while a stainless double bowl runs $150 to $500. The price difference is usually less than $50 for equivalent quality. Where you may save money with a single bowl is on installation: one drain, one strainer, and simpler plumbing connections can save $50 to $150 in labor costs. Premium materials like fireclay and composite granite cost the same regardless of bowl configuration.
Can I use a garbage disposal with a single bowl sink?
Absolutely. A garbage disposal works with any sink configuration. With a single bowl, the disposal connects to the single drain. With a double bowl, it typically goes on one side. Some people prefer having the disposal on one side of a double bowl so they can use the other side while the disposal runs, but this is a minor convenience. Most single bowl sink users find it's not an issue since you run the disposal briefly and then have the full sink available again.
