Cahaba CASS2522DISB-ADA-20.3 25 In. Standard Radius Single Bowl Drop-In Rectangle 20 Ga. ADA Stainless Steel Kitchen Sink - 3 Prepunched

No mounting hardware ships with it, and no basin rack either. Budget for drop-in clips, a bead of silicone or plumber's putty, and a strainer/drain assembly to finish the install. The sink itself is the only thing in the box.

Three prepunched holes in the deck. That's the standard widespread layout for a centerset or bridge faucet with two separate handles, or a single-lever faucet plus a side sprayer or soap dispenser in the third hole. If you're installing a single-hole faucet, you'll need a deck plate or accessories to cover the two you don't use, because the holes can't be filled after the fact.

It's a drop-in with a rim that sits on the counter, so it goes into an existing cutout as long as the opening is sized for a 25 by 22 inch sink and the old sink was also a top-mount. It will not work as an undermount, and it won't cover a cutout made for a larger sink. Measure the opening itself, not the old sink's rim.

20 gauge is a lighter stainless than the 16 or 18 gauge used in heavy commercial kitchens, so it will flex and telegraph noise more under a hard drop. For multi-family turns, rentals, and light-duty accessible kitchens it holds up fine and keeps the fixture cost down across a lot of units. If you're specifying for a commissary or a high-abuse institutional kitchen, spec a heavier gauge instead.

Center drain. A centered outlet puts the tailpiece right in the middle of the cabinet, which is the harder case for ADA knee clearance because the trap sits where a user's legs go. Plan on an offset trap arm or a wall-mounted trap kit and insulation on the exposed piping if this is going into an accessible workstation.

It weighs 8 pounds. One person can carry it up a stairwell and set it into the cutout without help, which is a real difference from a cast iron or fireclay drop-in of the same footprint. Handy if you're turning over multiple units.

Brushed stainless is the only finish it comes in. The satin brush pattern hides water spotting and light scratching better than a mirror polish, and it reads consistently against stainless appliances and brushed nickel faucets. Across a building where you're standardizing kitchens, every unit gets the same look.
