There are three ways a kitchen sink meets the surface it sits in, and they are not interchangeable. Confusing them costs a worktop, a cabinet or a container.

This page defines the cabinet-top format — the one that sits on top of the base cabinet itself rather than in a continuous worktop — and sets out how to specify it. It is written for importers, distributors, kitchen studios and cabinet manufacturers supplying residential kitchens.

What cabinet-top means

A cabinet-top sink sits directly on the base cabinet and is the top surface over that cabinet. The sink's rim rests on the cabinet edges and the sink covers the whole cabinet footprint. There is no separate worktop underneath it and no cut-out to make.

This is the reason the format persists. In a kitchen assembled from individual base units rather than from a continuous worktop run, the sink unit arrives as a cabinet plus a sink that drops onto it. There is no fabrication step, no template, no CNC cut, and no worktop to ruin. Installation is a two-person lift and a plumbing connection.

Because the sink defines the surface, the sink dimensions have to match the cabinet dimensions — not a cut-out inside a larger surface. That is the essential difference from every other format.

Cabinet-top versus inset versus undermount

Inset and cabinet-top are the two most often confused, because both are top-mounted and both show the rim. The distinguishing question is simple: is there a worktop with a hole in it, or is the sink itself the top? If the sink covers the cabinet, it is cabinet-top.

Which cabinet widths it fits

Because the sink is the surface, it must match the cabinet it sits on. The relevant dimension is the outside dimension of the base unit, not an internal measurement.

What to establish for each model:

• The sink's overall length and width, which must correspond to the cabinet footprint
• Whether the format assumes a single base unit or a run of two
• The depth of the sink front-to-back against the cabinet depth, since a sink that overhangs the front is both unsafe and visually wrong
• Whether the model is intended for a corner unit, which changes the geometry entirely

Standard base-unit widths in the target markets follow the common European progression, and cabinet-top sinks exist in sizes built around them. We are not going to print a size table on this page, because the sizes that matter are the ones we actually have — see the model pages linked below and the range overview, and ask us for the current list if a size you need is not shown.

For manufacturers matching sinks to their own cabinet programme, the dimensional discussion continues in sink specifications for kitchen furniture manufacturers.

Typical sizes in this format

Cabinet-top sinks tend to cluster around a smaller set of sizes than inset sinks, precisely because they are tied to standard cabinet footprints rather than to a freely chosen cut-out.

Rather than list sizes here that may not match current production, work from the product pages: browse the stainless steel sink range. Each model page states its overall dimensions, bowl dimensions and mounting format where those have been verified.

If a model page does not state the format, treat it as unconfirmed and ask. We would rather answer the question than have a container arrive in the wrong format.

Bowl layouts available

The format constrains layout more than inset does, because the sink footprint is fixed by the cabinet.

In practice the workable layouts are: a single bowl, which is the most common and leaves room for a drainboard section; a single bowl with an integrated drainboard, where the cabinet width allows; and a double bowl, which needs a wider cabinet and generally means two smaller bowls rather than two full-size ones.

A note on multi-variant models: some model references exist in more than one confirmed configuration. Model 8050 is one of them — it is confirmed both as a single bowl with drainboard and as a double bowl without drainboard. Always order against the specific product page for the variant you want, and do not treat the model number alone as a description of the layout.

Installation effort and who installs it

This is the format's commercial advantage and it belongs in your sales argument.

There is no cut-out, so there is no fabrication, no template and no risk of ruining a worktop. Installation is: place the sink on the cabinet, secure it, connect the waste and the mixer, seal the perimeter. It is within reach of a competent general fitter or a capable end customer, where an undermount installation is not.

For a distributor selling into renovation and self-installation channels, that materially widens the addressable buyer. For a kitchen studio, it lowers the labour cost on entry-level installations.

We are not publishing installation-time figures, because they depend on the fitter, the cabinet and the plumbing, and a number invented for a marketing page would not survive contact with a real kitchen.

Where this format is preferred

Cabinet-top is chosen where the kitchen is assembled from individual base units rather than built as a continuous run — which covers a substantial part of the renovation and replacement market, entry-level and rental fit-outs, and compact kitchens where a single base unit carries the sink.

It is not chosen where the kitchen has a continuous fabricated worktop, where the design calls for a seamless surface, or where the specification is premium and the visible rim is considered a compromise.

We are not going to attach a market-share percentage to any of that. We have no verified data on format split in these markets and inventing one would be a fabricated claim. What we can say is that the format is a distinct segment of demand and is worth carrying deliberately rather than by accident. For the compact-kitchen use case specifically, see sinks for apartment and compact kitchens.

How to specify the format

State the format explicitly in the enquiry. "Top-mount" is ambiguous and is read as inset by most suppliers:

Installation format: cabinet-top (overmount, sink forms the cabinet top surface)
Base cabinet width and depth:
Bowl layout required: single / single + drainboard / double
For multi-variant models, state the exact configuration required
Corner unit: yes / no

Send the cabinet dimensions and we will tell you which models fit. That is a faster route than working backwards from a size list.

What we supply

Pressed (drawn) stainless steel sinks are our core in-house line; handmade (welded) stainless steel sinks are a supplementary in-house line; quartz composite sinks are supplied to us by a partner factory. Mounting format is stated per model on the product pages.

Production lead time is 35 days. Minimum order quantity is 200 pieces per model for pressed, 50 for handmade, 20 for quartz composite. We quote EXW and FOB. The under-sink fitting set is included; the faucet is not.
