Direct answer: a sink with an integrated drainer and a double bowl sink solve the same problem in different ways. Both give the user a second surface beside the washing basin. A drainer gives a flat, ribbed area for air-drying and prep, while keeping one large basin intact. A double bowl gives a second full-depth basin. Which one sells better depends on washing habits and on how much width the base cabinet allows.
Who this guide is for
Importers, distributors, kitchen cabinet suppliers and private-label buyers deciding whether to add drainboard models to a range that already carries double bowl sinks, or the reverse.
What each configuration actually provides
Sink with integrated drainer (drainboard). One basin plus a shallower ribbed area beside it, formed from the same sheet in pressed construction. Water runs off the ribs back toward the basin or into a drain slot. Because the drainer is shallower than a second bowl, the overall unit can be wider without needing more depth, and the main basin stays large enough for a stockpot.
Double bowl sink. Two full-depth basins separated by a divider, each with its own drain. It supports two liquid tasks at once, but each basin is narrower than a single basin of the same overall width.
Comparison table
| Factor | Sink with drainer | Double bowl |
|---|---|---|
| Second surface | Shallow ribbed drying / prep area | Second full-depth basin |
| Large cookware in the main basin | Main basin stays wide | Each basin is narrower; 60/40 helps |
| Two liquid tasks at once | No (one basin) | Yes |
| Air-drying washed items | Designed for it | Possible, but uses a basin |
| Overall width requirement | Usually wider | Wider than single bowl, usually narrower than a drainer unit |
| Plumbing | One drain | Two drains |
| Typical demand driver | Hand-washing and air-drying routines | Wash / rinse separation habits |
Reading the demand signal
Both configurations exist because washing routines differ between markets. Where dishes are washed by hand and left to air-dry, a drainer is used every day. Where a dishwasher does the bulk of the work and the sink is used for pots and preparation, a single large basin or a 60/40 double bowl gets used more, and a drainer can sit unused.
That is a demand pattern to test against your own sell-through, not a rule. The practical approach is to carry both, put the drainer models where hand-washing is the norm, and keep a large single bowl and a 60/40 double bowl in the same width band so a showroom can offer a real choice.
Planning notes for distributors
- Check cabinet width before adding drainer models. Drainer units are wide. If your market’s standard base cabinet cannot take the overall width, the model will not sell regardless of demand.
- Keep the drainer and the double bowl in different widths where possible. Offering both in the same width forces a direct comparison; offering them in adjacent widths lets a buyer choose on cabinet fit.
- Confirm the drain position and the drainer fall. The drainer should slope back toward the basin. Ask how the fall is formed and whether the rib pattern is consistent between batches.
- Decide whether the drainer is a hero or a supplement. In some ranges the drainer model is the volume item; in others it is one or two SKUs that complete the offer. Decide which before you commit to MOQ.
- Remember the per-model minimum. Drainer models are pressed construction, so they carry the pressed minimum of 200 pcs per model unless you are ordering a handmade version.
Common sourcing mistakes
- Assuming a drainer replaces a second bowl. It does not hold water. Buyers who want to soak and rinse at the same time still need a double bowl.
- Ordering drainer models without checking cabinet standards. The single most common reason a drainer model underperforms is that it does not fit the local cabinet size.
- Specifying “with drainer” without saying left or right. Drainers are handed. State which side the drainer sits on.
- Comparing a drainer unit and a double bowl on overall width alone. The usable basin width is the number that matters.
Questions to ask your supplier
- Which side is the drainer on, and is the mirrored version available?
- What is the overall size and the minimum cabinet width?
- How is the drainer slope formed, and does water reliably run back to the basin?
- What is the usable width of the main basin?
- Is the model pressed or handmade, and what is the MOQ per model?
How this affects specification and quotation
Specify configuration (drainer left / drainer right / double bowl), overall dimensions, bowl split where applicable, drain position and cabinet width. Standard commercial terms are a production lead time of approximately 35 days, EXW Foshan or FOB Guangzhou, and T/T 30/70 payment.

Frequently asked questions
Does a drainer count as a second bowl?
No. A drainer is a shallow ribbed drying and preparation surface. It does not hold water and cannot replace a second basin for soaking or rinsing.
Are drainer models only available in pressed construction?
No. Drainer configurations exist in both families; confirm construction and MOQ on the specific model, because pressed and handmade carry different minimums.
Which sells better, drainer or double bowl?
It depends on local washing habits and on cabinet widths. Carry both where the cabinet standard allows and let sell-through decide the ratio.
Can I order the mirrored version?
Ask per model. Handing is a tooling question on pressed models, so availability varies.
What minimum applies?
Per model: 200 pcs for pressed, 50 for handmade, 20 for quartz composite.
