What Is the Standard Size for Double Bowl Kitchen Sinks?
When choosing a suitable double-bowl kitchen sink, one of the most important things to understand is the size. The dimensions matter not only for fitting into your base cabinet comfortably, but also for ensuring enough bowl space and clearance for installation and use. Let’s explore typical sizes, what influences them, and how to select a sink that works for your kitchen layout.
Typical Dimensions
For a double-bowl kitchen sink (two separate bowls side by side), here are the common size ranges:
| Dimension | Typical Range | Notes |
|---|---|---|
| Width (left-to-right) | About 33-36 inches (84-92 cm) in many models. | This size suits most standard base cabinets (30-36″ wide) in typical residential kitchens. |
| Larger widths | Up to 48 inches or more (≈122 cm) in some double-bowl sinks. | These are used in larger kitchens or when both bowls need generous space. |
| Depth (front-to-back) | Standard depth around 22-30 inches (≈56-76 cm) for the outer sink size in some cases. | Ensures you have enough front-to-back bowl space and still leave counter work space. |
| Bowl depth (vertical) | Commonly around 7-10 inches (≈18-25 cm) for each bowl. | A deeper bowl helps for large pots/pans, but may require more bending. |
So, to summarise: for a standard home kitchen, a double-bowl sink around 33″ wide and about 22–30″ deep is very typical. It’s important to measure your cabinet (especially the base cabinet width), the counter cutout, and ensure the plumbing and mounting style allow for the size you choose.
Factors That Affect Size Choice
Base Cabinet Width Most kitchens use base cabinets that are 30″-36″ wide for a sink module. If your base cabinet is 36″ wide, you could easily fit a sink around 33″ width. If your cabinet is smaller, you need a narrower sink or perhaps a single-bowl instead.
Number & Size of Bowls With a double bowl, you might have a 50/50 split (two equal bowls), 60/40 split or even 70/30 (one bowl larger, one smaller). The actual usable size of each bowl depends on how the manufacturer divides the space. If you want each bowl to be roomy (for large cookware, baking trays), you’ll lean toward a wider sink.
Installation Style Whether the sink is drop-in (top mount), undermount, apron-front, or workstation affects how the size interacts with countertop cut-out, prep space and cabinetry. For example, when undermounting, you’ll want an edge clearance and good support.
Kitchen Size & Layout In a large kitchen with a big island, you might choose a large double bowl (40″+ width) since you have the space. In a smaller kitchen, a more compact double bowl (or even a single bowl) might be more appropriate.
Countertop & Surrounding Space You need enough countertop on either side of the sink for food prep, drying dishes or placing items. If your sink is too wide, it may crowd the surrounding workspace.
Key Measurements to Check Before Buying
Cabinet width: Measure inside the base cabinet where the sink will go. The sink width must be less than the cabinet width (and allow for mounting hardware).
Countertop cut-out: The manufacturer usually provides a template for the cut-out.
Plumbing clearance and disposal: Make sure the space below allows for bowls of a given depth and size.
Edge to edge: Measure the available counter depth (front to back) to ensure the sink will not extend too far or interfere with countertop overhangs, backsplashes or windows.
Bowl size: Look at the actual interior bowl dimensions (length, width, depth) especially if you frequently wash large items.
Why Choosing the Right Size Matters
If the sink is too narrow, you may end up with cramped bowls, hard to fit large pans or trays, and less comfortable workflow (e.g., washing and rinsing).
If the sink is too wide and the cabinet or countertop cannot support it properly, you might compromise adjacent work space or need to modify cabinetry.
A well-sized Double Bowl Sink allows one side to be used for washing or soaking and the other for rinsing or prepping, thus improving kitchen workflow.
Example Standard Size
An example from a product listing: a 33″ x 22″ double‐bowl model. Another reference states that double bowl sinks can extend up to 48″ width. Also: for double sinks a common range is length (width) 80-120 cm (≈31.5-47″) and width front‐to‐back about 48 cm (≈19″) for some markets.
Recommendation – Where to Buy
If you’re looking for reliable manufacturers of Kitchen Sinks, you might consider LANSIDA (based in China). Their website states they were established in 2004, focused on high quality kitchen sinks, including double bowl styles. Choosing a manufacturer like LANSIDA can give you access to a wide range of double-bowl models, different sizes, and design options.
Summary
A good “standard” width for a double-bowl kitchen sink in many homes is around 33″ wide (≈84 cm).
Depth (front to back) is typically around 22-30″ depending on countertop space.
Bowl depth is usually around 7-10″.
Bigger widths (36″-48″) are possible and desirable in larger kitchens or when you want spacious bowls.
Always check cabinet width, countertop cut-out, bowl interior dimensions and installation style.
Choose a sink size that balances bowl space with surrounding workspace.
Consider reputable brands/manufacturers like LANSIDA when shopping.
By paying attention to these size considerations, you’ll ensure that your double-bowl sink fits the space well and functions efficiently in your kitchen.
