This Karran QU-812-CN is a single-bowl undermount kitchen sink in a Concrete finish, built from quartz composite and designed to mount beneath quartz, solid surface, or granite countertops. It arrives in a nested pallet of 20, making it the right choice for multi-unit residential builds, cabinet shops specifying multiple kitchens, or contractors working through a volume project.
Concrete as a kitchen finish has grown from a specialty aesthetic into a mainstream specification request, especially in urban renovations, loft builds, and contemporary kitchen remodels where the design intentionally moves away from bright whites and warm wood tones. This sink anchors that palette. The muted gray-brown of the Concrete finish reads as a neutral against dark cabinetry, integrates cleanly with poured or engineered concrete countertops, and sits quietly beside quartz slabs in warm gray or charcoal tones.
The single bowl configuration suits kitchens where counter space drives the layout decision: one large, deep basin handles pots, sheet pans, and oversized cutting boards without a divider getting in the way. At 9 inches inside depth, it carries real working volume without requiring a taller base cabinet.
The sink body is quartz composite, an engineered material that combines quartz with resin to produce a dense, consistent basin. The Concrete finish runs through the material rather than sitting as a surface coating, so chips and nicks do not expose a contrasting color underneath. The matte surface of the Concrete colorway is practical in a working kitchen: it does not show every water spot the way a polished or light-colored surface would, and the non-porous nature of the quartz composite keeps residue from bonding to the basin.
Cabinet shops and contractors working through multi-kitchen projects benefit from the pallet format: 20 sinks ship nested together, which simplifies receiving and storage on a busy job site. Designers specifying an industrial or contemporary kitchen will find the Concrete finish fills a gap that white, black, and standard gray sinks do not cover. The 36-inch minimum cabinet width aligns with the standard base cabinet most builders are already running, so the fit question is straightforward.
This is an indoor undermount sink intended for dry installation into a solid countertop material. It is not rated for ADA-compliant configurations. The undermount method means it is planned into a new countertop fabrication; it is not a drop-in replacement for an existing cutout.
It is designed for undermount installation into quartz, solid surface, and granite countertops.
No. Undermount quartz sinks are planned into new countertop fabrication. This is not a drop-in replacement for an existing opening.
The 3-1/2-inch drain opening is the standard kitchen size and accepts basket strainers and disposal flanges sized for that opening, sold separately.
The nested pallet format is designed for multi-unit projects. Twenty sinks ship together to reduce freight complexity and simplify on-site receiving when multiple kitchens are being built at once.
Choose this sink when the design calls for a muted, industrial finish and the project scope calls for more than one, a single-bowl quartz undermount that ships in a full pallet and installs cleanly under a solid countertop.
