    STOCK LINE

    A single bowl undermount kitchen sink to stock

    Fifty pieces is the entry quantity for S3018, a 30 inch single bowl in SUS304. It carries our Most Popular tag, and it is the under mount stainless steel sink to start a distributor range with.

    One uninterrupted bowl

    No divider, so the specification has one bowl to check and one drain location to confirm.

    Small-radius corners

    Small-radius corners maximize basin space and stay easy to wipe down, unlike sharp zero-radius wells.

    10 inch depth

    Every unit is 10 inches deep, 254 mm, so one depth figure goes on the schedule.

    SUS304, 18 gauge

    Steel is 1.2 mm SUS304 with a brushed stainless finish, the same on every unit.

    FIT DATA

    30 by 18 inch cutout and cabinet check

    S3018 measures 30 by 18 by 10 inches, or 762 by 457 by 254 mm. It is tagged for sink bases from 30 to 32 inches wide.

    Finish

    Measure the clear inside width of the base unit and compare it with 30 inches, as you would for any of our kitchen sinks. Side panels and face frames reduce the space a sink can use.

    Eighteen inches front to back leaves deck room behind the bowl for a faucet. Check the cabinet depth against the 10 inch bowl before the countertop is cut.

    Ask the fabricator to confirm the cutout edge against the drawing, because the reveal is set on site and not by the sink.

    APPLICATIONS

    Single bowl kitchen sink for volume projects

    Distributor and project orders often want one single bowl kitchen sink that every unit shares, and undermount kitchen sinks suit that brief. A single bowl removes the question of bowl split, so the specification stays short and the order list is easy to audit when cartons arrive.

    Stone fabricators cut the countertop to the bowl opening, and the undermount rim leaves a clean counter edge. A single 30 inch template can repeat unit after unit.

    Where a project needs a divided bowl, our double bowl undermount kitchen sinks uses the same steel and finish, so a mixed scheme looks consistent across kitchens.

    WIDTH CHOICE

    Where a 30 inch body wins over longer sinks

    Longer single bowls give more room across the bowl but need a wider cabinet. S3018 is the 30 inch option for base units at the smaller end of the range.

    The 30 to 32 inch width tag shows the span of sink bases it is made for. Buyers with mixed cabinet widths can check which kitchens fall inside that span.

    If a kitchen needs a different bowl count, ask for a double bowl code in the same finish rather than a different steel.

    If the cabinet is not a standard 30 inch run, send its drawing with the quantity and we confirm the options before the quotation.

    SPEC WRITING

    How to write the S3018 line in a specification

    Name the model code, the SUS304 material and the 18 gauge thickness in one line. Add the brushed stainless finish and the undermount mounting so the schedule reads the same to the purchaser and the installer.

    Attach the drawing to the line and quote the 10 inch depth on it. Installers use that figure to check the trap and disposer clearance before they plumb the sink.

    Send the model code and quantity with the drawing request, and we return the drawing against the same line.

    For a phased project, repeat the same code on every line. One model code, one material line and one drawing keep each delivery checkable against the first.

    CERT & DRAWINGS

    Certification and paperwork for S3018

    cUPC
    cUPC certified model

    Ask for the certificate details that match S3018 and your destination market.

    S3018 is cUPC listed. Volume changes the delivery schedule rather than the paperwork, so give us the destination market and total quantity with the first enquiry.

    The spec sheet and the dimensioned drawing are issued against S3018 on request. Both give a cabinet maker and a stone fabricator what they need to start, and both can go into the submittal pack.

    FAQs

    What steel grade and gauge does this under mount stainless steel sink use?

    S3018 is fabricated from SUS304 stainless steel at 18 gauge, which is 1.2 mm, with a brushed stainless finish. It is a handmade undermount sink built at our Foshan factory. Every unit in an order has the same grade, gauge and finish. State the material line on each order line so the schedule and the cartons match.

    What are the inside corners like on S3018?

    S3018 has a small radius, so the corners are tight and the bowl keeps its usable width instead of giving it up to large curves. The surface is still easy to wipe down. If you prefer larger radius corners, ask which rounded corner models we offer in a similar size.

    Is S3018 a good single bowl undermount kitchen sink for a housing project?

    Yes, when the project wants one large bowl and a 30 inch cutout repeated across many units. Outline, depth and finish stay identical on every sink, so one cabinet survey covers the build. Send the unit count and phasing and we plan deliveries around it.

    Can we order custom sizes and low MOQ for a project?

    Yes. As a direct manufacturer of stainless steel kitchen sinks, we offer OEM/ODM, custom cabinet sizing and low MOQ for distributor and project orders. Send your drawing and target quantity, and we confirm what changes in the cutout before we quote.

    How long does an S3018 order take?

    Lead time is 30–45 days after sample approval, and the minimum order is 50 pcs. If your programme has a fixed opening date, tell us at the enquiry stage and we work back from it. Send the quantity, destination port and Incoterm so the quotation covers the full delivery.
