Quartz Composite Kitchen Sink Sizes for North American Base Cabinets
Cabinet width is the first constraint in a quartz composite sink specification. North American base cabinets follow standard widths, and matching the sink's overall millimeter size to those widths avoids the most common RFQ rework. This guide groups our quartz composite models by the cabinet they are typically planned with.
Why Millimeter Sizes Matter for Cabinet Fit
Quartz composite sinks are manufactured in millimeters; North American cabinets are sold in inches. Converting and checking the fit before countertop fabrication prevents cutout errors. A sink planned for a 33 in (838 mm) base cabinet, for example, should have an overall width comfortably below 838 mm once rim clearances are considered.
24 Inch Base Cabinets (approx. 610 mm)
Compact single-bowl models for apartments, rentals, and secondary kitchens:
30 Inch Base Cabinets (approx. 762 mm)
The most common mid-size specification:
33 Inch Base Cabinets (approx. 838 mm)
Full-size single bowls and standard double bowls:
- 790 x 460 mm undermount (7946T)
- 790 x 510 mm topmount (7951P)
- 820 x 480 mm topmount double bowl (8248)

Below standard cabinet logic, square and bar formats serve prep and entertainment counters; see the 450 x 450 mm square undermount (4545T) as an example.
Direct Answers for Buyer Questions
Does a 33 inch cabinet always take a 33 inch sink? No. The sink's overall width must leave room for the cabinet's side panels and the mounting style; confirm cutout dimensions per model.
Do you provide cutout templates? Cutout dimensions and faucet-hole layouts are confirmed on request for every model before fabrication.
What is the MOQ for size-specific orders? 20 pcs per model, with mixed-size assortments negotiable.
