One Deep Bowl, No Compromise on Workspace

A single-bowl configuration earns its place in a working kitchen when the priority is fitting large pots, full sheet pans, or oversized cutting boards under the faucet without splitting the basin. The 9-inch bowl depth gives clearance for taller items, and there is no divider to work around. This sink suits a primary kitchen installation where one wide, deep basin serves washing, rinsing, and soaking all from the same bowl.

Gray Quartz That Reads as Part of the Countertop

Quartz composite gives this sink a density and visual weight that reads closer to stone than to a typical cast basin. The gray finish coordinates naturally with white, charcoal, or concrete-toned countertops, and because the color runs through the body of the material, minor surface wear does not expose a different shade underneath. Undermounting this sink beneath a hard surface countertop keeps the counter plane continuous from edge to bowl, which makes wiping debris directly into the basin straightforward and leaves no rim seam to collect residue.

Who This Sink Is Built For

This sink fits best in a new kitchen build or a full remodel where the countertop is being fabricated. Undermount installation requires a countertop that supports it, specifically granite, quartz, or solid surface, and the sink is designed for new countertop installations rather than drop-in replacement. Cabinet shops and contractors specifying a 36-inch base run will find the 32-inch side-to-side footprint fits the standard opening cleanly. Designers working with gray or neutral palettes get a sink that disappears into the color story instead of competing with it. Homeowners planning a hard-surface kitchen remodel get cUPC and IAPMO certification confirming the unit meets plumbing code.
