American Standard Portsmouth 32 x 18-Inch Stainless Steel Undermount Double-Bowl ADA Kitchen Sink - AMS-18DB6311800S

The 6 inch bowl depth is what makes it an ADA sink. A shallow bowl leaves knee clearance under the counter for a seated user, and the drains are offset to the rear so the tailpiece and trap sit back out of the way. If you don't need accessible clearance, a deeper bowl gives you more working room.

Both are in the box. You get two 9028000.075 waste fittings and the 791676-100.0070A undermount sink clips, plus the cutout template and instructions. What you still need to buy is the faucet, the P-trap and tailpiece assembly, and silicone or the adhesive your fabricator specifies for setting the sink to the stone.

No. It's an undermount sink, so it needs a solid-surface top with a finished, polished cutout edge, granite, quartz, or solid surface. Laminate has an exposed particleboard core at the cutout and won't support an undermount installation. For a laminate top you need a drop-in or top-mount sink instead.

18 gauge is the standard commercial-quality thickness for residential stainless sinks, a step up from the 20 and 22 gauge sinks that oil-can under load. The Portsmouth also adds SoundSecure+ sound pads and StoneLock undercoating on the underside, which cut the drumming when a disposer runs and reduce condensation on the cabinet floor. Note that American Standard classifies this one as a residential sink, not a commercial-duty unit.

It ships in one configuration only, stainless steel finish, part number 18DB6311800S.075, so there are no finish or size options to track across a spec. Every accessible unit gets an identical 6 inch deep double bowl with offset drains on a 36 inch base cabinet, which keeps your rough-in and your trap kit the same door to door.

Probably not without rework. The drains sit offset rather than centered under each bowl, which moves the tailpieces back toward the wall compared with a standard double-bowl sink. Plan on repiping the trap arm and continuous waste when you swap from a conventional sink, and expect the disposer to hang further rearward in the cabinet.
