Karran Quartz Black Single Bowl Sink Kit

Karran quartz black single bowl undermount sink kit is a 33-1/2 inch wide by 21 inch deep quartz sink designed for undermount installation into quartz, granite, and solid surface countertops, so it suits common kitchen remodeling layouts using these materials. The sink is made from 80% natural quartz crystals and pure acrylic resin, creating a dense, engineered surface that supports everyday kitchen tasks. Its durable quartz material is non-porous, preventing the spread of germs and bacteria, which keeps the bowl surface more hygienic during food prep and cleanup. Heat resistance up to 535 F allows the sink to withstand rapid temperature changes from hot and cold water, so typical hot pots and pans contact will not affect the material under normal kitchen conditions. The sink belongs to the quartz sinks product class, giving installers and builders a clear match when specifying quartz-based kitchen fixtures.

Quartz Sink Details That Support Daily Use

• The durable quartz material is described as extremely stain, scratch, abrasion, and impact resistant, which helps the sink maintain its appearance in busy kitchens where heavy cookware and utensils are used regularly.
• The non-porous quartz surface prevents the spread of germs and bacteria, so routine cleaning leaves fewer places for contaminants to cling, supporting a cleaner food preparation and dishwashing area.
• Heat resistance up to 535 F and the ability to withstand rapid temperature changes from hot and cold water protect the sink surface during typical cooking workflows, where hot items and sudden temperature shifts are common.
• The rear drain location provides more storage room in the cabinet below, because plumbing is shifted toward the back, opening up more uninterrupted space for organizers, trash pullouts, or cleaning supplies.
• The 9 inch deep bowl provides plenty of room to accommodate cookware, so large pots, pans, and baking trays sit fully in the basin instead of crowding the countertop, streamlining cleanup.
• An approximate weight of 35 lbs gives installers a sense of handling and support needs during undermount mounting, helping plan bracing and lift steps when working under the countertop.

Undermount Installation And Cabinet Fit Details

This Karran QU-722-BL-PK1 quartz sink is designed for undermount installation into quartz, granite, and solid surface countertops, so fabricators can cut and polish the opening knowing the sink is intended to hang from the underside of rigid, stone-like materials. The minimum cabinet size required is a 36 inch sink base cabinet, which sets the lower cabinet width needed for framing, bracing, and clearance around the 33-1/2 inch wide bowl. A drain opening size of 3-1/2 inches matches a standard kitchen sink drain diameter, streamlining the selection and installation of compatible strainers and related plumbing fittings under the bowl.

How This Quartz Sink Performs In The Kitchen

Single Bowl Quartz Sink In Real Use

The Karran 33-1/2 inch wide by 21 inch deep quartz black single bowl undermount sink kit provides a single, uninterrupted basin, which suits washing large cookware and handling oversized items without center dividers getting in the way. Its 9 inch deep bowl offers generous vertical clearance, so stock pots, sheet pans, and tall pitchers can sit fully in the basin during soaking or rinsing. The rear drain location frees up more space toward the front of the cabinet, so items can be stored there without interference from the main plumbing path. The non-porous quartz material prevents the spread of germs and bacteria, so residues from food prep are less likely to remain in tiny surface pores, supporting straightforward wipe-down cleaning after cooking sessions. The sink is part of Karran's quartz sinks class, aligning visually and materially with other quartz elements in a kitchen.

Material And Design Supporting Long-Term Workflow

The construction of this sink from 80% natural quartz crystals and pure acrylic resin creates a solid surface engineered for daily kitchen loads, so installers can expect the bowl to handle routine impacts from dishes and utensils. The quartz material is described as extremely stain, scratch, abrasion, and impact resistant, which helps reduce visible wear in homes where the kitchen sink sees frequent heavy use. Heat resistance up to 535 F and the ability to withstand rapid temperature changes from hot and cold water means thermal stress during cooking and cleaning does not affect the sink under typical kitchen conditions. The non-porous surface simplifies cleaning routines because it does not absorb spills, supporting consistent appearance over time. A 3-1/2 inch drain opening size and compatibility with most garbage disposals allow the sink to integrate into common North American drain and disposal setups.
