    SR3218 VS SR3218B

    Stainless steel single bowl undermount kitchen sink, 32 inch

    SR3218B and SR3218 look alike on a schedule, yet they are not the same sink. SR3218 measures 18 by 10 inches in front-to-back size and depth, while SR3218B, a single bowl kitchen sink, has an 18.2 inch footprint with a shallower 9.3 inch bowl.

    Overall Size
    32" x 18.2" x 9.3" (813 x 463 x 236 mm)
    Corner
    Rounded
    Depth
    9.3" (236 mm)
    Mounting
    Undermount
    Material
    SUS304 stainless steel, 18 gauge (1.2 mm)
    Finish
    Brushed stainless

    Installation type is undermount, so the stone edge frames the bowl instead of a drop in rim. Pick SR3218B when the cabinet takes 18.2 inches front to back and a 9.3 inch bowl. Pick SR3218 when the full 10 inch depth matters more. Never swap one for the other after the cutout is approved.

    BOWL SHAPE

    Rounded corners on a 32 inch single bowl kitchen sink

    A single bowl has no divider, so the 32 inch width stays open. Next to a double bowl, it leaves one clear work area. The generous corner radius is quicker to clean than a tight square corner.

    A zero-radius bowl has square corners. SR3218B uses a rounded corner for faster cleaning and a softer look, at full 32 inch width.

    Brushed SUS304 at 18 gauge (1.2 mm) is the same on every unit.

    Our Foshan factory fabricates the bowl by hand. Custom sizes and finishes are available for projects.

    PROJECT FIT

    Where these stainless steel undermount sinks get specified

    Distributor ranges

    Carry SR3218B beside SR3218, two stainless steel undermount sinks, so buyers can choose a 9.3 or 10 inch bowl on the same 32 inch width.

    Contractor projects

    One 32 inch cutout repeats across units of this kitchen sink, with low MOQ project supply direct from the factory.

    Shallower cabinets

    The 9.3 inch bowl, 236 mm, suits a base cabinet that cannot take the deeper SR3218.

    FAQs

    Which depth does this stainless steel single bowl undermount kitchen sink use?

    Depth is 9.3 inches (236 mm) inside a 32 by 18.2 inch outline, in SUS304 steel at 18 gauge (1.2 mm). That suits standard base cabinets. If a project needs a full 10 inches of depth, quote SR3218 instead and check its cutout separately.

    How do rounded corners differ from a zero-radius single bowl?

    Generous radius corners clean faster than tight square ones and give the basin a softer shape, while keeping full usable width at 32 inches. Choose by cleaning routine and by how the sink looks in the finished kitchen. SR3218B is rounded, so ask for the drawing before the countertop is templated.

    Can SR3218B replace SR3218 on a single bowl project?

    Only after you recheck the cutout. The two codes differ in front-to-back size and depth, so approve a drawing for each. Mixed use on one order is fine when each code has its own line and its own carton marking.

    Do you offer custom sizes, OEM/ODM and low MOQ?

    Yes. We provide OEM/ODM branding, custom sizes and finishes, and low MOQ project supply direct from the factory for distributors and contractors. Send the drawing and quantity you need and we confirm what each change does to the cutout before we quote.

    What does a developer need to send for a quotation?

    Send the quantity, the inside width of the base unit and the destination port. If you need a custom size or finish, add that too. Minimum order is 50 pcs and lead time is 30-45 days after sample approval. Our Foshan factory plans the schedule from those figures.
