Single bowl vs. double bowl: Which is better?

Over the past decade, single-bowl kitchen sinks have become the clear favorite in both professional and residential kitchens. The reason is simple. Removing the center divider creates uninterrupted bowl space, which dramatically improves how a sink functions day to day.
I know this topic better than anyone writing about it. I invented the workstation sink in 2010, and I have spent 27 years designing custom sinks and 22 years as a professional kitchen designer. I have had personal consultations with thousands of homeowners across the country. What I am sharing here is not opinion. It is what I have learned from decades of watching how real families actually use their kitchens.
With a single-bowl sink, large cookware finally fits the way it should. Stockpots, woks, roasting pans, baking sheets, and half-sheet pans can lie flat inside the bowl. A lasagna pan can soak completely without angling it awkwardly while water splashes onto the countertop. Cleanup becomes faster, calmer, and far more controlled. The depth of that bowl matters just as much as the configuration - see our ergonomic sink depth guide to understand how bowl depth affects your comfort and posture.
That said, many homeowners still hesitate because they are used to the traditional double bowl setup. One side for soaking, one side for rinsing or drying. If that describes you, there is an important evolution you need to understand.
The fastest growing trend in kitchen design today is the workstation sink.
A workstation sink is almost always a large single bowl sink that incorporates integrated interior ledges. These ledges allow functional accessories like cutting boards, colanders, and drying racks to slide across the sink. When properly designed, a workstation sink delivers the benefits of both single and double bowl sinks without the compromises of either.
The key detail most brands get wrong is drainage. If you are looking for a budget-friendly, well-made, and well-designed stainless steel workstation sink, take a look at our Foundation Series. For our full custom stainless steel workstation sinks, including the Signature Series™, explore the complete range.
Online forums are filled with complaints about workstation sinks that pool water or allow splashing onto the drying side. The issue is not the concept. It is poor engineering. A properly designed workstation sink must be intentionally sloped toward the drain.
At Rachiele® Custom Sinks, the slope from the shallow working side to the drain can be as much as one full inch, depending on sink size. Water cannot travel uphill. That simple fact allows you to wash on the drain side while the opposite side remains dry and usable for prep or drying.
When executed correctly, a workstation sink is not a trend. It is the most functional evolution of the single bowl sink ever created.
If you are deciding between a single bowl and a double bowl sink, the real question may be whether your kitchen deserves a sink designed for how you actually cook and clean today.
If your kitchen layout presents unique challenges, you may also want to explore our custom corner sinks - a single bowl configuration designed for kitchens where a standard run of cabinetry is not possible.
Frequently Asked Questions
Is a single bowl sink harder to keep clean than a double bowl? No - and in most cases it is easier. A single bowl has no center divider, which means no crevice where grime collects. The entire interior surface is open and accessible.
What size single bowl sink do I need? For most households, a 36" to 42" single bowl is the practical sweet spot. It accommodates full sheet pans and large cookware while fitting standard cabinet runs. I design every Rachiele® sink to your exact cabinet opening, so size is never a compromise.
Can I soak and rinse at the same time in a single bowl sink? Yes - when the sink is properly engineered. A Rachiele® workstation sink slopes toward the drain by as much as one full inch, so one side of the bowl stays dry and usable while the drain side handles water. This is the function a center divider used to serve, done better. We also offer the Add-a-Bowl™, a removable bowl that hangs from the workstation ledge and can be filled independently for soaking - giving you true two-zone functionality without a divider.
What is a workstation sink and how is it different from a standard single bowl? A workstation sink is a single bowl sink with integrated interior ledges that allow accessories - cutting boards, colanders, drying racks - to slide across the sink at counter height. I introduced the first workstation sink in 2010. When properly engineered, it replaces the double bowl entirely.
Do single bowl sinks work for families? They are often the better choice for families precisely because of the uninterrupted space. Large loads, large cookware, and bathing pets or children are all easier in a single bowl. The workstation accessories handle the task separation that a divider used to provide.
