American Standard Delancey 18 x 16-Inch Cast Iron Undermount Single-Bowl Kitchen Sink - AMS-77SB16180

You need a minimum 21 inch (533 mm) base cabinet. The sink itself is nominally 18 x 16 x 8 inches (457 x 406 x 203 mm), so the extra cabinet width covers the rim and the mounting clips under the counter. Anything narrower than 21 inches won't take it.

The bowl measures 14-13/16 inches (377 mm) wide by 12-13/16 inches (326 mm) front to back, with an 8 inch (203 mm) depth. The 18 x 16 figure is the outside nominal size, not the bowl. That interior will take a standard dinner plate or a small sheet pan flat, but a full-size 18 x 26 sheet pan will not lie flat.

No. It's built for undermount installation only, so it needs a solid-surface countertop (stone, quartz or similar) that can be cut and polished to the bowl and carry the weight of cast iron from below. It won't sit on a laminate top the way a drop-in rim sink does.

No deck holes. As an undermount cast iron bowl there's no faucet deck on the sink at all, so the faucet, sprayer and any air gap or soap dispenser get drilled into the countertop behind the bowl. Plan those hole locations with your fabricator when the top is templated.

The Delancey is enameled cast iron in brilliant white. Cast iron is heavier and quieter than stainless under running water and holds a gloss porcelain surface that wipes clean, but it needs support under the counter because of the weight, and a dropped cast pan can chip the enamel. Stainless is lighter and won't chip, but it scratches and shows water spots. If you want a white sink that matches a porcelain look, cast iron is the way to get it.

One finish only: Brilliant White, ordered as 77SB16180.308. There's no other color on this model, so for a multi-unit property where every kitchen should match, you're ordering the same white bowl every time.
