COLOUR ROUTES

Charcoal rectangular concrete basin C0021 in four finishes

C0021 comes in four finish routes: GG black as standard, full-body cement colour, particle colour or two-tone colour. Pick the route first, because it decides what the approval sample has to show.

GG black, the standard

The default black concrete finish, with a dark architectural tone that suits hotel and commercial washrooms.

Full-body or particle colour

Colour runs through the casting or shows as speckle, for distributors building a distinct range from the same shape.

Two-tone colour

Two colours on one casting, for a range that needs a contrast piece. The combination is fixed on a physical sample before mass production.

SIZE AND FORM

500 × 325 mm of rim on the vanity top

Size: 19.7" × 12.8" × 4.7" (500 × 325 × 120 mm)
Shape: Rectangular
Mounting: Above-counter (vessel)
Colour: Charcoal
Rim: Thick rim, rounded inner corners
Bowl: Smooth interior

Each basin is hand-cast, so tone and surface texture vary slightly from one casting to the next.

CONSTRUCTION

Thick rim, soft corners: a dark concrete sink

A thick rim gives C0021 a solid, dark edge on the counter. Inside, the corners are rounded and the bowl is smooth, while the exterior carries a textured concrete surface. The design pairs a hard outline with a soft interior.

Beside our oval concrete vessel, C0021 is shorter and much lower on the counter. Its straight sides line up with a straight countertop edge, which suits long vanity runs.

Dark concrete sinks suit a modern or industrial bathroom style, and the textured exterior keeps the look raw rather than polished.

VANITY LAYOUT

Planning a bathroom run around 500 mm concrete sinks

In a residential bathroom or hotel project, C0021 sits on top of the counter, so the countertop material and depth set the layout. At 325 mm front to back, check that the top leaves space behind the bowl for a deck-mounted faucet, or plan a wall-mounted tap.

Plumbing needs early attention before installation. The waste position and any tap drilling are confirmed on the spec sheet, so cut the top from that sheet, and check the faucet height against the 120 mm rim.

Weight matters on the cabinet: concrete is heavier than ceramic at the same size. Confirm the vanity can carry the basin before the top is ordered, especially on wall-hung cabinets in hotel rooms.

Ask for sealing and care guidance with the sample, so housekeeping or homeowners can clean and maintain the surface from day one.

ORDER DETAIL

Four items to write into the C0021 order

Color standard

Name the finish route and keep the approved sample. Write the acceptable surface variation and inspection standard into the order, since textured and particle finishes vary most.

Drain and faucet

State the drain hardware and faucet type, so the layout can be adjusted on the drawing before the top is cut.

Carton and labels

Specify carton marks and barcode needs, ensuring the packing matches your sales channel.

Documents

Request the cUPC certificate reference and spec sheet for the project file.

ORDERING

Lead time and packing for C0021

MOQ is 20 pcs and a typical lead time is 30–45 days. Logo cartons and custom colours go through our OEM and ODM service.

Send model, quantity and destination port by email. We confirm the packing method and carton size on the quotation.

Mixed loads are accepted, so C0021 can share the 20-pc minimum with other SANIKB concrete basins. Agree the inner packing with the quantity, because a hand-cast concrete body needs packing sized for its weight.

C0021 Black Rectangular Concrete Basin with Textured Exterior

The C0021 black rectangular concrete basin is built for B2B buyers who need a compact, design-forward countertop basin for commercial bathroom projects, showroom programs, and private-label collections. Its rectangular form, thick rim, rounded inner corners, smooth inner bowl, and textured concrete exterior give it a stronger product identity than standard ceramic basins.

Model: C0021
Product type: black rectangular concrete basin / concrete vessel basin
Nominal size: 500 × 325 × 120 mm
Technical drawing dimensions should be confirmed before bulk order approval
Suitable for countertop vanity installation
Recommended for hospitality bathrooms, commercial washrooms, multifamily projects, and showroom displays

Custom Color Options for OEM and Private-Label Bathroom Lines

The standard GG black concrete finish gives this basin a modern architectural look for bathroom collections that require a darker, more distinctive product style. For distributors, importers, and private-label brands, optional color directions can help support different market segments and product series.

Standard color: GG / black concrete finish
Optional colors: full-body cement colour, particle colour, and two-tone colour
Textured exterior surface creates a concrete-style visual effect
Smooth inner basin area supports practical daily use

SANIKB can support bulk quotation, private-label discussions, and project-based purchasing for distributors, importers, builders, contractors, and hospitality procurement teams.

OEM/ODM support available for qualified B2B buyers
Private-label carton, logo, and packaging options can be discussed
Sample request: available for specification and finish review
Export packaging should be confirmed based on order quantity and shipping method
Buyers may request product drawings, specification sheets, and packing details before bulk order

FAQs

How big is C0021, and which drawing governs the final size?

Nominal size is 500 × 325 × 120 mm (19.7" × 12.8" × 4.7"). Technical drawings can carry slightly different measured values, so we confirm the production drawing, tolerance and carton size with you before a bulk order is approved. Cut the vanity opening only from that confirmed drawing.

Is the charcoal rectangular concrete basin C0021 suited to commercial washrooms?

Yes. This concrete sink suits hospitality bathrooms, commercial washrooms, apartment projects and showroom displays. Before approval, confirm vanity depth, faucet position and drain compatibility against the drawing, since the basin sits on top of the counter and shows any misalignment at the edge. Sealing and maintenance recommendations are confirmed at order stage, so ask for them with the sample.

Which colour options does C0021 offer beyond GG black?

GG black concrete is standard. Optional directions are full-body cement colour, particle colour and two-tone colour. Colour samples are reviewed and approved before mass production, so a distributor can lock the tone for a whole series. Hold the sample beside the vanity top and wall finish it will join, since screen colour is not a reliable reference.

Can C0021 ship in private-label cartons?

Private-label packaging can be discussed for B2B orders: custom cartons, labels, logo placement and barcode requirements, depending on quantity and sales channel. Export packaging is set by shipping method. Tell us your channel and we reply within 12 business hours.

What are the MOQ, lead time and certification on C0021?

Order from 20 pcs; typical lead time runs 30–45 days. C0021 is cUPC certified, and we provide the certificate reference on request. Drawings, spec sheets and packing details are available before the bulk order is confirmed, so your installer and freight forwarder can plan from the same documents.
