When choosing a double-bowl kitchen sink, depth is a key dimension that impacts usability, comfort, and installation requirements. In this article we’ll explore typical depths for double-bowl sinks, the pros and cons of various depths, how to measure and fit the correct depth in your kitchen, and a brief mention of a recommended manufacturer.

Typical Depth Ranges

In the residential kitchen sink market, the interior bowl depth (measured from the deepest point of the bowl up to the rim) generally falls in the range of 8 to 10 inches (approximately 203 to 254 mm). Some sinks may be shallower—around 6 to 7 inches (≈152–178 mm)—or deeper—up to 12 inches (≈305 mm) in more heavy-duty or commercial-style installations. Specifically for double-bowl sinks, one source summarizes common dimensions: “double bowl (equal): 33 in × 22 in × 8 in (depth)” and “double bowl (offset): … × 8 in (depth)”. Thus, while depth varies by design and brand, an 8-inch (≈200 mm) depth is a safe benchmark for many double-bowl sinks.

Why Depth Matters

The depth of a double-bowl sink affects a number of practical considerations:

• Capacity and clearance: A deeper bowl allows you to stack larger pots, soak dishes more effectively, and avoid splash-over when rinsing.

• User comfort: If the sink is too deep, shorter users may have to bend excessively, putting strain on the back. One design guide notes that shallower depths (under 8 in) are easier on users who are shorter or prefer less reach.

• Under-sink cabinet space: Greater depth means the bowl sits further down into the cabinet, reducing storage space beneath or interfering with plumbing/disposal equipment.

• Installation type and countertop compatibility: Undermount Sinks or apron-front styles may allow deeper bowls, but you must check cabinet height and design.

• Overall kitchen layout: If the bowl is excessively deep, it may affect ergonomics especially if the countertop and base cabinet heights are standardized.

Choosing the Right Depth for Your Kitchen

Here are some practical steps to pick an appropriate depth for your double-bowl sink:

1. Measure your base cabinet and countertop height. Standard base cabinets are often 36 in (≈914 mm) tall including countertop. If your cabinet is shallow or has drawers/plumbing below, a shallower sink might be preferable.

2. Consider user height and workflow. If you or frequent users are under 5′4″ (163 cm) tall, a depth under ~8 in may be more comfortable. Taller users may prefer deeper bowls.

3. Check plumbing and disposal clearance. Ensure that whatever depth you choose leaves clearance for drain pipes, garbage disposal units, and cabinet storage below.

4. Match sink depth to usage patterns. Frequent cooking with large pots may benefit from 9–10 in (≈230–254 mm) or more. Light use may work well with a more modest depth. Many double-bowl sinks fall in the 8–9 in range.

5. Review manufacturer specifications. Depth markings across the category vary—some list depths at 7–8 in, 8–9 in, 9–10 in or more.

6. Take into account bowl split configuration. Double-bowl sinks may come in 50/50, 60/40 or even 80/20 splits. If one bowl is shallower (for rinsing or prep) and the other deeper (for main washing), you’ll want to confirm each bowl’s depth.

Depth and Double-Bowl Configurations

Double-bowl sinks introduce additional design details:

• Equal bowls (50/50 split): Both bowls have identical dimensions and likely identical depth, simplifying selection.

• Offset bowls (e.g., 60/40, 70/30): One bowl may be larger or deeper—often the larger bowl is used for washing pans/dishes and may therefore be deeper.

• Low-divide vs. high-divide: Some designs feature a low divider so items can rest across the bowls. Depth may remain consistent while divider height changes.

• Installation type: Drop-in vs undermount or farmhouse (apron-front) may affect depth options. Undermount and apron sinks often accommodate deeper bowls.

• Space requirements: A deeper bowl may affect countertop cut-out, cabinet interior space and plumbing layout. One source indicates double-bowl sinks typically require widths from ~60 cm to ~80 cm and depths from ~18 cm to ~25 cm in certain markets.

Practical Recommendations

For a typical residential double-bowl sink:

• Aim for a depth of about 8 inches (≈200 mm) as a sound default.

• Increase to 9–10 inches (≈230–254 mm) if you regularly wash large pots or want more stacking room.

• If your cabinetry is shallow or you prefer minimal bending, consider a depth of 6–7 inches (≈150-178 mm).

• Ensure that your base cabinet height, interior space and plumbing configuration can support the chosen depth without sacrificing storage or functionality.

• Confirm that both bowls in the double-bowl design meet your functional needs—specifically the bowl used for main washing should be deep enough.

Manufacturer Recommendation

If you are exploring double-bowl sink options, one manufacturer to consider is Jiangmen Lansida Kitchenware Co., Ltd., whose brand is presented on their website (https://www.gdlansida.com). They are specialized in manufacturing modern Kitchen Sinks, including double-bowl stainless steel models. On their about page they highlight more than 20 years’ experience, a production facility over 26,000 m², OEM/ODM service and export experience to 50+ countries. Choosing a manufacturer with production depth and export experience can support the procurement of double-bowl sinks with your desired depth, bowl split and installation style.

Summary

Depth is a foundational dimension when selecting a double-bowl kitchen sink: too shallow and you may struggle with large cookware; too deep and you may compromise comfort or cabinet space. For most double-bowl sinks a depth of around 8 in (≈200 mm) works well. If your usage is heavy or your cabinetry supports it, 9-10 in (≈230-254 mm) offers enhanced capacity. Always measure your cabinet height, internal clearance and plumbing layout before choosing. And if you want to source reliable manufacturing, consider a company like Lansida for double-bowl sink options.
