American Standard Colony 25 x 22-Inch Stainless Steel 4-Hole Topmount Single-Bowl Kitchen Sink - AMS-20SB.8252284S

It's a topmount (drop-in) sink. The rim sits on top of the counter, so it works on laminate, wood, or stone without the edge finishing an undermount requires. A cutout template, mounting hardware, and instructions come in the box.

Four holes are punched in the deck. That covers a standard 8 inch widespread or centerset kitchen faucet with a sprayer or soap dispenser in the fourth hole. If you're running a single-hole pull-down faucet, you'll want a deck plate to cover the extra three.

The bowl measures 21-1/4 x 15-3/4 x 8 inches inside, within a 25 x 22 inch overall footprint. Eight inches of depth handles a full-size sheet pan or a stock pot, and the single-bowl layout means no divider getting in the way of oversized cookware.

The Colony is 20-gauge stainless with two sound treatments built in: SoundSecure rubber pads bonded to the underside of the bowl, and StoneLock multi-layer spray insulation. The spray coat also cuts condensation forming under the sink, which matters if you've got a disposal or stored cleaning supplies in the cabinet below. It's specified as a residential sink, so it's suited to apartments and single-family turns rather than a commercial kitchen.

What ships with the sink is the mounting hardware, the countertop cutout template, and the installation instructions. Plan on ordering the strainer basket or disposal flange, tailpiece, and trap separately, along with the faucet.

American Standard 20SB.8252284S.075 is the stainless steel finish, and it's the only configuration this Colony model comes in. Use that number when you're matching sinks across multiple units so every kitchen gets the same bowl and the same hole count.
