Charcoal rectangular vessel
What C0040 actually is: a bowl that sits on top of the counter
The published envelope for C0040 is 23.6" × 11" × 7.1" (600 × 280 × 180 mm). Charcoal is the tagged colour and the mounting is above-counter (vessel).
Outline of 600 × 280 mm
The published outline is 600 × 280 mm, with a body 180 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
Clearances to check before the top is cut for C0040
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 C0040 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
Why two charcoal castings never match exactly
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
cUPC listing and the papers that travel with C0040
Carton marks and language requirements vary by port. Send yours in writing before the packing is printed.
C0040 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
How C0040 is normally bought
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 C0040 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 C0040
- 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.

A named account manager follows up by email or WhatsApp, confirms the specification and clarifies anything missing before pricing.
