The Sunstone Premium Drop-In Sink is a commercial-quality, hand-built sink crafted from food-safe 304 stainless steel, 18-gauge construction. Designed with a zero-radius rectangular shape (21" x 21" x 9" H), the sink features angled top edges, sharp polished corners, and 45° and 90° angles, adding a modern, sophisticated look to your outdoor kitchen.

The extra-deep basin measures 10" interior height, and with the cover in place, it provides 12" total interior height, leaving 2" of clearance for cutting board food prep. This versatile design ensures ample space for washing, prepping, and cleanup tasks.

The complete sink package includes everything needed for a fully functional setup: hot and cold chrome-plated faucet, matching soap dispenser, cutting board, sink basin grid, 2" raised cover with handle, and kitchen-sized drain.

As one of Sunstone’s top-rated and best-selling models for over 15 years, this sink has been refined through years of design and customer feedback to deliver time-tested durability, functionality, and style. Experience Sunstone quality redefined and bring your outdoor kitchen vision to life.

The Drop-In Single Sink A-SS17 is ideal for those seeking quality, durability, and everyday functionality in both outdoor and indoor bar environments. Crafted entirely from premium 304 stainless steel on all interior and exterior surfaces, this sink ensures food safety, corrosion resistance, and long-term performance. A hot and cold water faucet along with a matching soap dispenser are included, providing complete convenience without the need for additional accessories.

With overall dimensions of 16-1/4" W × 17-1/2" D × 6-1/2" H, the sink integrates easily into a wide range of countertops. The required cutout size is 15" W × 16-1/4" D × 5-1/2" H, while the sink bowl measures 12" W × 10-1/2" D × 6" H. This thoughtfully sized basin offers ample room for washing glassware, prepping ingredients, or rinsing produce, all while maintaining a compact footprint.

Installation is simple thanks to the drop-in design, which allows the sink to rest securely within the countertop cutout. It performs especially well with thicker countertop materials, and all mounting hardware is included. The sink comes ready to use with a kitchen-sized drain, 3-3/4" drain opening, and drain stem, making it compatible with most garbage disposal systems.

A light brushed #4 horizontal stainless steel finish complements Sunstone grills, outdoor kitchen appliances, and other stainless fixtures. The polished chrome faucet and soap dispenser handles add a refined accent and cohesive look.

For added confidence, Sunstone supports the Drop-In Single Sink A-SS17 with a 3-year warranty on structure and finish, plus a 1-year warranty on the handle, faucet, soap dispenser, and drain, ensuring lasting performance and visual appeal.
