What Information to Send
for a Kitchen Sink RFQ
A useful sink quotation starts with more than an overall size. Installation, bowl dimensions, material thickness, finish, accessories, packaging and expected quantity can all affect the production route and price.
You do not need every detail before contacting Matrix. Start with what you know, and missing specifications can be reviewed during the quotation process.
What Should I Send for a Kitchen Sink Quote?
For a useful kitchen sink quotation, send the sink type, installation method, overall dimensions, bowl dimensions and depth, stainless steel grade, material thickness or gauge, corner radius, drain position, faucet-hole requirements, finish, accessories, logo or private-label requirements, packing method, target market and expected order quantity. Drawings, specification sheets or reference photos are helpful when available. If the product is not fully defined yet, start with the target market, sink type, approximate size and quantity so the production route can be reviewed first.
Minimum Information vs. Complete RFQ
Minimum Information

Use when the buyer is still selecting products.
- Target Market
- Sink Type
- Approximate Overall Size
- Installation Type
- Expected Quantity
- Reference Photo / Current Model (if available)
This is usually enough to start a product and production-route discussion, but not always enough for final pricing.

Kitchen Sink RFQ Checklist
Use the checklist below to prepare the technical and commercial information most commonly needed for stainless steel sink quotation and feasibility review.
01 Product & Market
| RFQ Item | What to Provide | Example | Why It Matters |
|---|---|---|---|
| Target Market | Country / region where the product will be sold or installed | USA Canada Australia EU Middle East |
Market expectations can affect dimensions, installation, accessories, packaging and product positioning. |
| Sink Type | Product category or reference model | Single bowl Double bowl Workstation Drainboard Apron front Commercial sink |
Sink structure affects manufacturing method, tooling, material use and accessories. |
| Manufacturing Preference | Handmade / Pressed / Not sure | Handmade | Handmade and pressed production have different customization flexibility, tooling requirements and MOQ logic. |
| Installation | Installation method | Undermount Top mount / drop-in Flush mount Apron front |
Rim design and overall dimensions depend on how the sink is installed. |
| Quantity | Expected quantity per model and total order quantity | 300 pcs/model 3 models |
Quantity can affect production method, MOQ, tooling decisions, packaging and unit cost. |
02 Dimensions & Structure
| RFQ Item | What to Provide | Example | Why It Matters |
|---|---|---|---|
| Overall Dimensions | Length × width | 800 × 500 mm or 32 × 19 in |
Overall size determines cabinet fit, countertop opening and manufacturing feasibility. |
| Bowl Dimensions | Internal bowl length × width | 720 × 400 mm | Two sinks with the same overall size can have very different bowl capacity and rim structure. |
| Bowl Depth | Target bowl depth | 220 mm or 9 in |
Depth affects capacity, material forming, cabinet clearance and product positioning. |
| Corner Radius | Target internal corner radius | R0 R10 R15 |
Radius affects appearance, cleaning, fabrication and mold structure. |
| Drain Position | Center / rear / offset position or drawing dimensions | Rear center | Drain location affects plumbing, usable bowl space and workstation accessory layout. |
| Faucet Holes | Quantity, diameter and position | 1 × Ø35 mm hole | Hole requirements should be confirmed before production rather than modified after finishing. |
03 Material & Finish
| RFQ Item | What to Provide | Example | Why It Matters |
|---|---|---|---|
| Material Grade | Required stainless steel grade | SUS304 SUS316 |
Material grade affects cost, application and corrosion resistance requirements. |
| Thickness / Gauge | Material thickness or gauge for the top part and bowl | 1.0 mm 1.2 mm 18 Gauge 16 Gauge |
Thickness affects material cost, structure, product positioning and manufacturing feasibility. |
| Surface Finish | Target finish | Brushed Satin Nano Black PVD Gunmetal Gold |
Finish affects appearance, production process, MOQ, accessory matching and packing protection. |
Note: For pressed / drawn sinks, clarify whether the requested thickness refers to incoming sheet thickness or a minimum finished-sink measurement where relevant.
04 Accessories & Branding
| RFQ Item | What to Provide | Example | Why It Matters |
|---|---|---|---|
| Accessories | Complete accessory list or target sink set | Drain Bottom grid Roll-up rack Colander Cutting board |
Accessories affect product cost, workstation compatibility, packaging and SKU configuration. |
| Logo | Logo requirement, method and preferred position | Laser logo on sink body | Logo method and position should be reviewed against the finish and visible product area. |
| Label / Barcode | SKU label, barcode or customer label requirement | EAN barcode + model label | Private-label products often require product identification beyond the sink itself. |
05 Packaging & Commercial Information
| RFQ Item | What to Provide | Example | Why It Matters |
|---|---|---|---|
| Packing | Standard export carton / individual carton / pallet / retail packing | 1 pc / branded carton + pallet | Packaging affects cost, shipping protection, warehouse handling and brand presentation. |
| Private-Label Carton | Logo, artwork, SKU, barcode and carton-mark requirements | Printed brand logo + model label | Carton printing may have its own MOQ and artwork confirmation process. |
| Target Starting Quantity | Expected trial quantity and potential repeat quantity if known | Trial: 100 pcs/model Repeat: 500 pcs/model |
This helps review whether handmade, existing pressed tooling or new tooling is commercially appropriate. |
| Delivery Requirement | Target timing and destination when relevant | FOB Shenzhen Required by November |
Production and packing planning depend on the required delivery schedule and shipment method. |
| Drawing / Reference | PDF, CAD, DXF, STEP, Specification sheet, Product photo, Physical sample | PDF Drawing | A reference helps reduce interpretation errors and speeds feasibility review. |

Do I Need a Technical Drawing to Request a Quote?
No. A technical drawing is helpful for custom or specification-sensitive projects, but buyers can also begin with an existing model, product photo, current supplier specification sheet or physical reference sample.
Existing Matrix Model
Best for:
Faster early quotation and existing-tooling review.
Reference Photo
Best for:
Early product direction when dimensions are not fully defined.
Technical Drawing
Best for:
Custom sizes, project sinks and detailed OEM specifications.
Physical Sample
Best for:
Matching an existing product structure or benchmarking a current SKU.
The more customized the product, the more important it becomes to freeze dimensions and details in an approved drawing before production.
Does the RFQ Change for Handmade and Pressed Sinks?
| RFQ Item | Handmade | Pressed / Drawn |
|---|---|---|
| Custom Size | High flexibility | Usually depends on existing mold or new tooling |
| Bowl Depth | Can be reviewed within fabrication limits | Defined by mold and drawing capability |
| Corner Radius | Flexible within manufacturing limits | Defined by mold structure |
| MOQ | Typically more flexible | Affected by mold and production setup |
| Tooling | Normally no full drawing mold required for basic custom fabrication | Existing mold or new tooling should be confirmed |
| Sample Development | Custom sample can often be developed directly from drawing | New design may require tooling development first |
Details That Usually Need Clarification
Only overall size provided
Why it creates uncertainty: Bowl size, depth and rim design remain unknown.
"304 Sink" without thickness
Why: Material grade alone does not define product construction.
"Black Sink" without finish type
Why: Nano coating and PVD / colored finishing may have different production requirements.
Accessories shown only in a photo
Why: The required drain, grid, rack or workstation set may be unclear.
No quantity
Why: Production route, MOQ and tooling decisions may depend on expected volume.
Custom design without drawing
Why: Drain position, bowl geometry and installation details may remain open to interpretation.
Private label without packing requirement
Why: Logo, label and carton requirements can affect MOQ and total cost.
