Drop-In Kitchen Sinks

Drop-in (top-mount) kitchen sinks that set into a cut-out and rest on the counter via a self-rimming edge, for straightforward installation on almost any worktop. The selection runs across quartz composite, fireclay and stainless steel in single- and double-bowl layouts, widths from 18 to 33 inches, and finishes including white, grey and matte black. A practical choice for residential kitchens, rental properties and project work. Custom sizes, bowl counts and finishes can be specified on request.

Footprint first, then material

Drop in kitchen sinks in four materials

This drop in kitchen sink range covers 32 self-rimming models. Stainless steel carries most of the size spread, while quartz composite, fireclay and solid surface add color and texture options. The listing is built around the self-rimming format, which rests on the counter edge, so the cut-out size is the first thing to settle.

Nineteen of the 20 stainless models give both an overall size and a bowl size (TD3322 gives its overall size only), so the cut-out discussion can start from the model code.

Gauge, depth and corner side by side

Stainless steel drop in sink models compared, single bowl and double bowl

All 20 stainless units are 304 steel. What separates them is gauge (16G only on the TW ledge series and TD3322, 16G or 18G on the rest), whether bowl depth is fixed or selectable, and which corner radius options are listed.

Beyond steel

Quartz, fireclay and solid surface drop in sink models compared

These twelve non-steel models are where finish becomes the deciding spec. Three quartz bodies share the 33" × 22" × 10" shell in two colors, as single and double bowl layouts, which makes a matched black-and-white program straightforward.

Turning a cut-out into a quotation

How to brief us on a top-mount order

Pricing is quoted per order with MOQ set per model, and written replies arrive within 12 business hours. These details let the first reply be a usable quote. Installation starts with an accurate cut-out, so the exact model code comes first.

  1. Give the model and the variant

    Name the exact code, such as 6356A-3 versus 6356A-4, or the fireclay size within the SN single bowl series, since the same shell can differ by hole count or width.

  2. Pick gauge and depth where offered

    For 16G/18G models, state which gauge; for selectable-depth models, state the bowl depth per quantity line.

  3. Specify finish and corner

    Quartz buyers should split counts between black and white; stainless buyers on DB, HMT or TW lines should name the corner radius.

  4. Add branding and mixed-load plans

    For custom sizes, bowl counts or finishes, attach drawings and see our OEM/ODM service page, and list every model you want consolidated in one order.

Spec sheet files are published for the DB, HMT and TW stainless lines; for any other model, name it in the inquiry and ask for the details you need.

FAQs

What does this Drop-In Kitchen Sinks collection include?

This collection gathers our complete range of Kitchen Sinks built for top-mount installation: fireclay, ceramic, stainless steel and quartz composite drop-in models. Ceramic, fireclay, stainless and quartz models are all produced to SANIKB specification, so you buy every material through a single supplier.

Should I stock drop-in or undermount kitchen sinks?

Drop-in sinks rest on the benchtop with a supporting rim, so installation is faster and easier than undermount kitchen sinks, which clamp beneath the counter. Drop-ins suit laminate and timber tops, while undermount kitchen sinks give a seamless look on stone. We stock both to cover every project.

Which drop-in sinks does SANIKB actually manufacture?

Only our fireclay and ceramic drop-in sinks are cast in the SANIKB factory; you can see that ceramic depth across our fireclay sinks. Stainless steel and quartz composite drop-in models are produced to SANIKB moulds and specification under our quality control, so quality stays consistent across materials.

What is the minimum order and can I mix materials?

Mix freely. One full 20ft container from a single supplier is the minimum order, and you can combine drop-in fireclay, ceramic, stainless and quartz units along with other Kitchen Sinks in the same load. This consolidates your sourcing, simplifies logistics and keeps a full price range available across one shipment.

What happens if products arrive defective?

Yes. After-sales responsibility stays with us across factory-made and sourced lines alike. Any defective goods are replaced or fully compensated, and we never shirk responsibility. Whether you order drop-in models, undermount kitchen sinks or our fireclay sinks, quality problems are ours to resolve.

How do I get a wholesale quote?

Send your drop-in kitchen sink models, target materials, sizes and quantities, and we return tiered pricing, MOQ and lead times within 12 business hours. Browse the full Kitchen Sinks range first, then request a consolidated 20ft-container quote mixing any drop-in fireclay, ceramic, stainless or quartz units you need.
