Charcoal rectangular vessel
Charcoal concrete, 500 × 325 mm across the top
The published envelope for C0021 is 19.7" × 12.8" × 4.7" (500 × 325 × 120 mm). Charcoal is the tagged colour and the mounting is above-counter (vessel).
Outline of 500 × 325 mm
The published outline is 500 × 325 mm, with a body 120 mm deep. Check it against the top before the cut-out is set, because a squared bowl follows the counter edge and shows any error.
Charcoal carried through the body
Charcoal is the tagged colour on this model. Concrete is coloured through the casting rather than glazed, so a chip reads as the same material underneath instead of a white scar.
Rectangular formats are grouped in the rectangular concrete sink range, and the full line sits under concrete sinks.
Fit & Clearance
Fitting 500 × 325 mm of charcoal concrete without reworking the vanity
The published figures describe the outside of the basin. Waste position and tap drilling are confirmed on the spec sheet, not here.
Tap and waste are supplied separately. A vessel basin of this type has no tap hole in the body, so the tap is drilled through the counter or run off the wall. Send the C0021 spec sheet to whoever sets the plumbing — the waste centre is on it.
Concrete is heavier than ceramic at the same size. Confirm the vanity carries the loaded weight of the bowl before the top is ordered.
Hand-cast concrete carries a small dimensional tolerance; work to the drawing, not to a scaled photograph.
Construction & Finish
Approving charcoal on C0021 before the order runs
Each unit is hand-cast and hand-finished, so surface character belongs to the material rather than to a factory glaze.
Approve the colour against a physical sample
Charcoal is the part a client argues about. Hold a sample beside the sanitaryware and the worktop it will join before the order is released — screen colour is not a reference.
Tone and surface vary slightly between castings. That is normal for concrete and is worth writing into the customer's expectation at quotation stage rather than at delivery.
Sealing and any maintenance schedule are confirmed at order stage; ask for the current recommendation with the sample.
Ask for photographs of current production, not the catalogue image, before it goes onto a showroom shelf.
Compliance
What ships with C0021 on the documentation side
Carton marks and language requirements vary by port. Send yours in writing before the packing is printed.
C0021 is cUPC listed. Ask for the certificate reference with the RFQ so it can be attached to the submittal your specifier or plumbing inspector will want to see.
Export documentation is agreed per market and per shipment. Raise labelling and carton marking with the RFQ, before the packing is printed, rather than after the goods are made.
Procurement
Getting C0021 onto a packing list
The published minimum is 20 pcs, which usually means this model travels inside a mixed order rather than filling one on its own.
Mixed loads, private labelling and custom colour work are arranged through the SANIKB OEM and ODM program. Concrete travels well when it is packed for its own weight, so agree the inner packing at the same time as the quantity.
If C0021 is going into a project rather than a shelf programme, send the schedule of quantities with the RFQ so the lead time can be quoted against real dates.
Include these details with the RFQ
- Quantity against C0021
- Other models sharing the container
- Charcoal confirmed, or a custom colour to match
- Inner packing for a hand-cast concrete body
- Destination port and Incoterm
- Documents required in the destination market
Container space is quoted on the final packing list, not on this page.
How we work
From enquiry to shipment
A factory-direct process built for importers, distributors and project buyers. No trading layer in between.
-
01
Send the enquiry
Tell us the model, quantity, destination market and any branding or packaging requirement. A spec sheet or drawing helps but is not required to start.
-
02
Our sales team contacts you
A named account manager follows up by email or WhatsApp, confirms the specification and clarifies anything missing before pricing.
-
03
Quotation
You receive a written quotation with unit price, MOQ, packing details, lead time and the trade term you asked for. Entry, mid and premium build levels can be quoted side by side.
-
04
Sample approval
We send a sample for finish, function and packaging sign-off. Branded samples are produced once artwork is confirmed.
-
05
Production and shipment
Mass production starts after sample approval and deposit. QC and inspection run before loading, then the order ships to the agreed port.
OEM and ODM to your specification
We develop to a brief. Send a reference model, a drawing or simply the price band and market you are targeting, and we will propose what fits. Entry, mid and premium builds are all available from the same factory.
- Your logo on product, carton and documentation
- Private-label packaging and manuals
- Custom finish matched to your standard
- Custom dimensions and tooling where volume supports it
- Product development from your reference or price target
- Destination-market documentation prepared on request
