Karran quartz double bowl sink combines natural and man-made materials to create a work bowl that is scratch, chip, and heat resistant up to 530 F, so it handles daily kitchen tasks without surface damage from normal cooking heat. The 34 inch wide by 22 inch deep external dimensions provide a substantial work area that fits common kitchen cabinet layouts while still leaving room for surrounding countertop material. A 60/40 double bowl layout gives one larger and one smaller compartment, so you can separate washing, rinsing, or prep tasks in a way that matches real workflow. Both bowls have a 9 inch depth, which offers usable capacity for pots and pans while keeping reach manageable at the counter. The uniform color throughout the quartz construction means the bisque finish runs through the material, helping minor surface wear remain less visible in service.
This quartz kitchen sink is suitable for top mounting into any type of countertop, so it works with laminate, solid surface, stone, or other counter materials using a drop-in cutout. Top mounting supports installation from above, letting the sink rim rest on the countertop for support and sealing. All faucets must be sink mounted, so hole placement is focused on the sink deck rather than the countertop surface. That sink-mounted faucet requirement keeps water penetration points within the sink unit, which can simplify planning for some counter materials. External dimensions are approximate to 1/4 inch, giving a small tolerance range that installers can factor into cutout sizing. The double bowl 60/40 layout concentrates plumbing connections below a single sink footprint, which can help organize drain and trap runs within the cabinet.
The QT-721-BI quartz kitchen sink falls into the quartz sinks product class, so it is designed as a primary kitchen work sink rather than a bar or prep-only unit. Its 34 inch by 22 inch footprint matches many standard kitchen base cabinet arrangements, giving flexibility when planning layouts with existing or new cabinetry. The 60/40 double bowl configuration uses one larger and one smaller bowl, which supports cleaning in the larger side while keeping the smaller side free for rinsing or food prep. With both bowls at 9 inches deep, you gain vertical space for soaking pans and bakeware while still retaining ergonomic access at the counter edge. The bisque color aligns with the range of six available colors noted for this series - white, bisque, black, brown, concrete, and grey - which can help coordinate with cabinet and countertop finishes when selecting a color family. As a top mount design suitable for any countertop type, the sink can be planned into projects using diverse surface materials without changing the sink model.
The suitable for top mounting into any type of countertop statement means this sink is intended for a drop-in application, which centralizes the load on the sink rim and countertop edge for a stable installation. Because all faucets must be sink mounted with this model and no undermounting is allowed, the faucet drilling and installation occur directly on the sink deck, concentrating water and mechanical loads on the sink rather than the surrounding surface. Heat resistance up to 530 F allows hot water and cookware from cooking operations to contact the bowls without degrading the quartz structure, which supports long-term dimensional stability at the drain and deck areas. The non-porous surface that prevents bacteria build-up also resists liquid absorption, helping maintain the integrity of the sink body when exposed to common kitchen liquids and cleaners. Stated external dimensions being approximate to 1/4 inch indicate a modest manufacturing tolerance that installers can factor into cutout templates, supporting a balance between snug fit and ease of dropping the sink into the opening. The 25 years Limited Warranty against manufacturer defects provides a defined coverage period on the quartz sink itself, aligning with long-term kitchen service expectations.
The QT-721-BI quartz kitchen sink has external bowl dimensions of 34 inches by 22 inches by 9 inches, which sets the required countertop opening size and cabinet space.
This Karran quartz double bowl sink has both internal bowls at 9 inches deep, providing capacity for larger cookware while keeping reach into the sink manageable during use.
The larger bowl measures 17-5/8 inches by 17-1/2 inches by 9 inches, and the smaller bowl measures 11-1/8 inches by 16-1/8 inches by 9 inches, creating distinct work zones.
This bisque quartz double bowl sink is suitable for top mounting into any type of countertop, and all faucets must be sink mounted, so undermounting is not used.
The sink being heat resistant up to 530 F means normal hot cookware and water from cooking tasks can contact the bowls without damaging the quartz material.
The non porous surface prevents bacteria build-up, so residues stay closer to the surface and can be removed more effectively during regular cleaning.
The Karran 34 inch wide by 22 inch deep QT-721-BI bisque quartz double 60/40 bowl top mount sink provides defined bowl sizes, a 9 inch depth, and a non-porous, scratch, chip, and heat resistant surface up to 530 F. It is suitable for top mounting into any type of countertop with all faucets sink mounted, bringing a consistent installation approach across different counter materials.
