What C0004 actually is: a deep basin built for washing down, not for show
The published envelope for C0004 is 23.8" × 15.7" × 5.5" (605 × 400 × 140 mm). White is the tagged colour and the mounting is above-counter (vessel).
Outline of 605 × 400 mm
The published outline is 605 × 400 mm, with a body 140 mm deep. Check it against the top before the cut-out is set, because a curved outline gives no straight edge to line up against the counter front.
White carried through the body
White 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.
Oval formats are grouped in the oval concrete sink range, and the full line sits under concrete sinks.
Fit & Clearance
What the site team needs before C0004 arrives
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 C0004 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
White concrete, and what varies between castings (C0004)
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
White 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 C0004 on the documentation side
Carton marks and language requirements vary by port. Send yours in writing before the packing is printed.
C0004 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 C0004 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 C0004 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 C0004
- Other models sharing the container
- White 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.

Model C0004 is a rounded rectangular concrete utility sink designed for laundry rooms, mudrooms, garage wash zones, and commercial utility areas. With a 605 × 400 × 140 mm size, it offers a practical basin format for daily washing and rinsing tasks while adding a clean architectural look to project interiors.
The vertical ribbed exterior gives this concrete basin a stronger visual identity than standard smooth utility sinks, making it suitable for showrooms, private-label collections, and design-focused building projects. The standard color is WH, with optional full-body cement colour and particle colour available for buyers who need customized finishes for different market segments.
SANIKB supports distributors, importers, builders, contractors, project buyers, and private-label brands with factory-direct concrete sink supply. For bulk orders, buyers can discuss OEM/ODM customization, finish selection, export packaging, carton labeling, sample requests, and project documentation before submitting an RFQ.
