• Undermount installation for granite, quartz, and solid surface countertops, leaving the counter surface unbroken above.
• Single bowl with 9-inch interior depth to handle large pots and pans.
• Requires a minimum 27-inch cabinet width for proper fit and support.
• cUPC and IAPMO certified, meeting North American plumbing standards.
• 3-1/2 inch drain opening compatible with standard basket strainers and disposals.

Where White Works Hardest

White has stayed the most specified kitchen sink color because it reads as clean, pairs with any countertop pattern, and holds its own whether the kitchen runs modern, traditional, or transitional. In an all-white kitchen it disappears into the design. Against a dark granite or black quartz counter it becomes an intentional contrast. That flexibility is why designers reach for it as the neutral anchor of a kitchen layout, and why contractors stock it as the default when a customer has not yet settled on a countertop color.

This single bowl gives an uninterrupted basin, which makes it easier to submerge a stock pot, rinse a sheet pan, or work through a pile of dishes without the center divider of a double bowl getting in the way. The 9-inch depth adds clearance for tall items and helps contain splashing during heavy use.

Quartz Composite Material

The sink is made from quartz composite, a dense engineered material that carries the look and weight of stone while holding up to the thermal swings and daily impact of kitchen use. The White finish runs through the body of the material rather than sitting on top as a coating, so chips at the rim edge do not expose a contrasting core. Undermounting this material beneath granite, quartz, or solid surface keeps the transition between counter and bowl smooth and easy to wipe clean.

Planning the Install

This sink is designed for new countertop installations. It is an undermount only and is not suited to drop-in use or retrofitting into an existing cutout from a prior sink. The minimum cabinet width is 27 inches, so confirm the base cabinet measurement before ordering. For fabricators working in solid surface, the sink can be bonded seamlessly to the counter material. The drain opening takes a standard 3-1/2 inch basket strainer.
