How to choose a quartz composite kitchen sink

Quartz composite vs. granite composite: what is in this collection?

The 16 models currently listed in this collection are quartz composite kitchen sinks. They are not a separate range of granite composite sinks. Some earlier product names use “granite composite”; for the models listed below, the confirmed material is quartz composite. Choose by the exact model and its specifications, rather than treating the two material names as interchangeable.

Choose undermount or drop-in installation

Undermount sinks fit beneath a compatible countertop. Drop-in, also called topmount, sinks have a rim that rests on the countertop. This selection includes 12 undermount models and four drop-in models. Check the installation drawing, countertop suitability, support and existing cutout before ordering; a matching overall width alone does not establish compatibility.

Compare sizes and finishes across the 16 models

The dimensions below are overall width × front-to-back depth × height in inches, not interior bowl dimensions or countertop cutout measurements. All models listed here use quartz composite. Availability and included accessories vary by model.

Check cabinet space, cutout and plumbing separately

A 33-inch sink is not a sink for every 33-inch cabinet. Confirm the selected model's minimum cabinet requirement, interior bowl dimensions, countertop cutout and installation instructions. Allow space for mounting hardware, faucets, drain connections and any disposal. Ask your installer to confirm the fit before cutting the countertop.

Double bowl or workstation: choose for your routine

A divider can separate washing and rinsing, but reduces the uninterrupted room for large cookware. Compare the white undermount DC-GX3327 with the matte black drop-in DC-GX3329 for two double-bowl examples. Both are quartz composite, with different installation methods and overall dimensions. For other materials and layouts, browse our double bowl kitchen sinks.

Workstation models use a ledge for compatible prep accessories. The white undermount DC-GU0003WS, DC-GU55241, DC-GU7755 and DC-GU2514 list a cutting board, bottom grid, roll-up drying rack and drain assembly. The 33-inch drop-in DC-0001GBT and DC-0002GWT also list a colander. Do not assume every model includes the same accessory kit or a faucet.

Material, finish and care questions

White and matte black describe the finish, not a different composite material. This collection does not specify a common stone percentage, heat-resistance limit or scratch-proof rating for every model. Follow the care instructions for the exact sink; contact Dcolora product support for installation, care and replacement-part guidance.
