Grey rectangular vessel
What C1003 actually is: a bowl that sits on top of the counter
The published envelope for C1003 is 31.5" × 17.7" × 5.5" (800 × 450 × 140 mm) / 23.6" × 17.7" × 5.5" (600 × 450 × 140 mm). Grey is the tagged colour and the mounting is above-counter (vessel).
Outline of 800 × 450 mm
The published outline is 800 × 450 mm, with a body 140 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.
Grey carried through the body
Grey 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
Setting a 800 × 450 mm rectangular basin out on the top
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 C1003 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
Surface and sealing on a rectangular grey body
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
Grey 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
Certification and export documents for a rectangular concrete basin (C1003)
Carton marks and language requirements vary by port. Send yours in writing before the packing is printed.
C1003 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
Ordering C1003 at 20 pcs
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 C1003 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 C1003
- Other models sharing the container
- Grey 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.

The C1003 concrete ramp vanity sink is designed for B2B buyers who need a distinctive bathroom basin for hotels, multifamily developments, commercial washrooms, showroom displays, and private-label bathroom collections. Its rectangular concrete body and sloped ramp basin create a clean architectural appearance that helps differentiate project specifications from standard ceramic sink options.
Available in 800 × 450 × 140 mm and 600 × 450 × 140 mm, this model gives distributors, importers, builders, and contractors flexible sizing for different vanity layouts. The low-profile 140 mm height supports a modern visual profile while keeping the basin suitable for project-based bathroom planning.
The ramp-style basin is shaped to guide water toward the rear drain-cover area, creating a simple, linear look across the sink surface. This design is suitable for contemporary vanity spaces where buyers want a more architectural concrete basin instead of a traditional round or rectangular bowl.
The standard finish is manufacturer color code CAL. Optional finishes include full-body cement colour and particle colour, allowing buyers to evaluate different visual directions for private-label lines or project specifications. Finish samples can be requested before bulk order confirmation to support color approval and batch consistency.
SANIKB supports factory-direct concrete basin supply for distributors, importers, wholesalers, contractors, developers, and bathroom fixture brands. For this concrete ramp vanity sink, buyers can discuss OEM/ODM requirements, private-label packaging, carton labeling, product documentation, and export packing needs based on the target market and order plan.
For bulk orders or project supply, procurement teams may request size drawings, finish samples, MOQ details, lead time estimates, packaging information, and customization options before confirming production. This helps buyers compare specifications, control project risk, and prepare a more accurate RFQ.
