Key specs explained for you

Material: Composite Granite

This sink uses 80% crushed natural granite mixed with 20% proprietary resin. The stone provides extreme durability and heat resistance up to 356 degrees Fahrenheit. The resin makes the surface non-porous, which prevents staining and resists household chemicals. This blend offers more strength than quartz sinks. You benefit from a surface that withstands daily wear and maintains its color without discoloring over time.

Installation Type: Drop-In Topmount

This installation style means the sink rim rests on top of your countertop. The manufacturer provides cutout templates and mounting clips to secure the unit. This method is generally easier to install than undermount options. It is also simpler to replace later. You can retrofit this standard size into most existing topmount sink cutouts. This makes it a practical choice for straightforward kitchen upgrades or replacements.

Exterior Dimensions: 33" x 22"

The outside width is 33 inches and the depth is 22 inches. This is a standard size designed to fit most base cabinets. The interior bowl measures 30-1/4 inches wide by 16-3/4 inches deep.

Workstation Ledge: Built-in ledges

The sink features integrated ledges around the rim. These ledges allow you to install optional WorkReady accessories. You can use these ledges to place cutting boards, colanders, or drying racks directly over the basin. This design maximizes your workspace by keeping tools within reach. It transforms the sink into a functional prep station. Note that accessories are sold separately, so you must purchase them to utilize this feature.
