Karran QU-721-BI-PK1 Quartz Sink For Busy Kitchens

Karran QU-721-BI-PK1 quartz sink gives you a 33-1/2 inch wide by 20-5/8 inch deep double 60/40 bowl layout, so installers can fit a practical workstation into standard kitchen runs. The undermount design is engineered for granite, quartz and solid surface countertops, which supports a clean edge detail your clients expect on premium tops. The sink is made from 80% natural quartz crystals and pure acrylic resin, creating a hard-wearing basin that holds up under daily use. Heat resistance up to 535 F allows the bowls to handle hot pots and rapid temperature changes from cold and hot water without distortion, which supports long-term dimensional stability. The durable quartz material is non-porous, so it resists moisture absorption, helping limit germ and bacteria spread around the sink zone in normal use.

Key Quartz Sink Details That Support Daily Use

• The durable quartz material is extremely stain, scratch, abrasion and impact resistant, so the sink surface stands up to cookware, utensils and cleaning routines in a working kitchen.
• Rear drain locations free up more storage room in the cabinet below, giving space for pullouts or cleaning supplies under the sink run.
• The 9 inch deep bowls provide plenty of room to accommodate cookware, helping keep splashing down while still allowing space for larger pots and pans.
• The bisque quartz finish coordinates with quartz, granite and solid surface tops, supporting color-consistent installations in light-toned kitchen designs.
• The approximate 36 lbs weight reflects the solid quartz construction, which helps the sink sit firmly in a properly prepared undermount cutout.

Undermount Quartz Sink Fit And Installation Basics

This Karran quartz double 60/40 bowl sink is designed specifically for installation into granite, quartz and solid surface countertops, so fabricators can rely on predictable support around the rim. The minimum cabinet size required is a 36 inch sink base cabinet, which lets installers plan base layouts and door configurations accurately. Rear drain locations are set to work with standard 3-1/2 inch drain openings, streamlining connection to common kitchen plumbing components. The 9 inch deep bowls give vertical room inside the cabinet, while still leaving space below the drains for traps and typical under-sink storage layouts.

Using This Quartz Double Bowl Sink In The Kitchen

Where This Karran Quartz Double Bowl Sink Fits

This Karran quartz double bowl sink suits kitchens built with granite, quartz and solid surface countertops, because the undermount design is tailored to these rigid materials. The overall 33-1/2 inch width and 20-5/8 inch front-to-back dimension align with a 36 inch sink base cabinet, which is common in residential layouts and simplifies cabinet ordering. The double 60/40 bowl configuration creates a larger primary bowl and a smaller secondary bowl, giving homeowners a main space for washing while retaining a separate area for rinsing or prep. With 9 inch deep bowls, the sink handles tall pots and baking trays while still keeping the work zone contained below the counter height. Rear drain locations move plumbing toward the back, which opens the front of the cabinet floor for organizing common under-sink items. The 3-1/2 inch drain opening size supports connection to most garbage disposals, helping integrate waste management into a single fixture location.

Why The Material And Layout Support Repeatable Results

The sink is made from 80% natural quartz crystals and pure acrylic resin, creating a dense, consistent structure that fabricators can cut around for undermount installation in hard countertop materials. Heat resistance up to 535 F, along with the ability to withstand rapid temperature changes from cold and hot water, keeps the bowls stable when users move hot cookware from the cooktop or oven into the sink. The durable quartz material is extremely stain, scratch, abrasion and impact resistant, so the interior surfaces resist visible wear from metal pans and utensils over time. Because the material is non-porous, it does not harbor moisture in micro-voids, which helps prevent the spread of germs and bacteria typically found around sink work areas. Rear drain locations and 9 inch bowl depth give plumbers a consistent geometry to work with, reducing layout guesswork under the cabinet. The approximate 36 lbs weight reflects a substantial unit that works well with standard undermount support methods on solid countertop decks.
