    CONFIGURATIONS

    Square concrete sink C0023, factory-direct from Foshan

    Four colour routes sit on one compact square body: the GG grey shown, full-body cement colour, particle colour and two-tone colour. As a speckled square concrete basin C0023 supplier, SANIKB casts it itself, so each route is settled through a sample, not through a drop-down menu.

    Body outline: a 400 × 400 mm square with softened inner corners and a clean inner basin profile. The speckle lives on the exterior, which keeps the bowl easy to read from the room.

    Distributors and brand owners can start from the GG reference, then develop a series around it. Approve a physical sample first, because speckled concrete shows natural variation from piece to piece.

    Spec sheet carries the drain position. Square the bowl to the counter front, not to the wall behind.

    SQUARE VS ROUND

    Square against round and rectangular bowls

    Against round bowls

    Straight sides take more counter than a round bowl does. On a narrow top, that decides how much deck stays usable.

    Against rectangles

    Equal sides give a balanced top view, with no long axis to align against a mirror or shelf.

    Against smooth finishes

    Speckle gives the same square body more surface interest than a smooth finish. Check a sample before the model goes on your shelf.

    CERTIFICATION

    cUPC and care documents before the first container

    cUPC
    Reference on request

    State the destination market so the paperwork matches the shipment.

    C0023 carries cUPC certification, so ask for the certificate reference with your RFQ. Request care instructions and surface treatment details at the same time, so distributors can answer after-sales questions on their concrete sinks in advance.

    Sampling comes before the run on a model bought for its speckled surface, so budget the days. Branded cartons, product labels and care-instruction inserts are arranged through the OEM and ODM service.

    Before ordering, confirm model number, size, colour, approved sample, packaging method and drain compatibility. For project orders, review the spec sheet and installation details too.

    FAQs

    Which colours does the speckled square concrete basin C0023 supplier offer?

    Yes. Full-body cement colour, particle colour and two-tone colour are available beside the GG grey shown. For bulk orders, approve a physical sample first, because concrete texture and speckle vary naturally. The approved piece then becomes the benchmark for the full production run, and we keep it as the reference when you reorder.

    Is C0023 square or rectangular?

    Square. The top view is 400 × 400 mm, with straight sides and softened inner corners, and the body stands 120 mm high (15.7" × 15.7" × 4.7"). That balanced outline suits compact vanities where a rectangle would push the bowl toward the wall. Tell us the vanity depth if you are unsure.

    Will a square concrete sink work in hotel or apartment bathrooms?

    Yes. Among vessel sinks, the 400 × 400 × 120 mm body fits compact vanity layouts in hotel rooms, apartments, commercial wash areas and showrooms. Confirm countertop size, faucet position, drain compatibility and installation details before ordering, and use the spec sheet to check each one before the tops are cut.

    What should be confirmed before placing a bulk order?

    Confirm the model number, size, colour, approved sample, surface finish, MOQ of 20 pcs, lead time, packaging method and drain compatibility. We reply in writing within 12 business hours. Typical lead time is 30–45 days, and we confirm the date once colour and carton details are fixed.

    Does a concrete basin need special care instructions?

    Yes. Request care instructions, surface treatment details and cleaning guidance before listing or installing the basin. Passing them to end customers cuts after-sales questions and gives your sales team a written answer on upkeep for every project. Ask for these documents together with the quotation.
