Who it fits

Key specs explained for this sink

Material: Stainless Steel

This sink is built from stainless steel, a material known for resisting rust and corrosion in wet kitchen environments. You get a surface that is easy to clean and does not stain easily. This makes it a practical choice for high-traffic kitchens where hygiene and durability are priorities. It holds up well against daily wear better than many plastic alternatives.

Steel Gauge: 18 Gauge

The steel thickness is rated at 18 gauge. A lower gauge number indicates thicker, heavier metal. This 18-gauge construction offers solid durability and reduces vibration when water runs. It feels more substantial than thinner 20-gauge sinks. This thickness helps prevent denting and provides a quieter operation, which is a key spec to compare when shopping for quality.

Bowl Depth: 9"

The basin depth is 9 inches, which is deeper than standard sinks. This extra space allows you to wash large pots and pans without splashing water out. It accommodates bulky items like baking sheets or tall dishes easily. This depth is useful for soaking items or storing large quantities of wet dishes. It is a significant spec for families with large cookware.

Installation Type: Drop-In

This unit is designed for drop-in installation, meaning it rests on top of your countertop. This method is generally easier and faster to install than undermount options. It requires less precise cutting of the counter hole. This spec is important if you want a straightforward replacement or upgrade. It fits standard cutouts and provides a rim that seals against the counter.

The brushed finish resists visible water spots and fingerprints. You get a surface that is easy to clean and does not stain easily. The unit weighs 26 pounds, which provides stability during installation. It is designed as a drop-in model. This means you place it into a cutout in your countertop. The exterior dimensions are 32 inches by 18 inches. The interior basin measures 28 inches by 16 inches. The 9-inch depth allows you to soak large pots or commercial baking sheets. An integrated ledge runs along the top. You can slide accessories across this ledge. The listing includes a solid wood cutting board, a deep colander, a bottom grid, and a dish-drying roll-up rack. These items convert the sink into a prep station. The bottom grid keeps dishes elevated. This design helps water drain away from the steel surface. The center drain has X-grooves. These grooves slope gently toward the 3.5-inch opening. This layout prevents water from pooling. The sink requires a minimum cabinet size of 34 inches.

Setup and everyday use

This design allows for straightforward placement without complex undermount mounting hardware. The exterior dimensions are 32 inches by 18 inches, so you must ensure your cabinetry can accommodate this footprint.

Daily use centers on the integrated workstation ledge. This feature allows you to slide accessories across the sink basin.

These tools convert the sink into a prep area, reducing the need for separate countertop space. You can chop vegetables on the board or drain pasta in the colander directly over the basin.

Draining is managed by a center drain with a 3.5-inch opening, which fits most standard garbage disposal units.
