How it meets the countertop
The mount type decides what we cut, and what you see every day.
This is an undermount sink, and that is a decision about the stone rather than about the sink. The opening is cut to the bowl and its edge is polished, because with the sink hung underneath, that cut edge is what you see and what your hand runs over every day. There is no rim sitting on the surface, so crumbs go straight into the bowl instead of catching on a lip.

Size, depth, and the cabinet under it
The numbers off its own spec line, and what each one constrains.
Size
Figure on a base cabinet of at least 27" — the rule of thumb is bowl width plus about three inches for the cabinet sides. We measure your actual run at template rather than trusting the rule.
- 23 1⁄4"x 21"
Depth
A shallower bowl, which means less bending to reach the bottom and less room to hide a stack of plates. On a vanity that is the right trade; in a working kitchen it is a real one.
- 8"

Questions about 18G 2321
Answered from this fixture’s own catalog attributes — nothing generic.
How does 18G 2321 mount?
Undermount — the deck stays flat and unbroken, and the bowl is clipped up underneath it. Worth knowing before you shop: the mount is a decision about the countertop as much as the sink, and a laminate top cannot take one. This one measures 23 1⁄4"x 21" across and 8" deep, so it wants a 27" base cabinet.
How many bowls does 18G 2321 have?
A single bowl — no divider. It is the layout that has quietly taken over kitchens, for the simple reason that dishwashers made the second basin redundant and oven trays never fit in one anyway. The bowl is 23 1⁄4"x 21" across and 8" deep, so it wants a 27" base cabinet.
What is 18G 2321 made of?
Steel, 18 gauge, with sound-deadening pads underneath the bowl. Thickness is what you are really buying in a stainless sink: a thin one flexes under a full pot and rings under the tap, and no amount of finish hides either. At this size the gauge is worth caring about: a full-size bowl is where thin steel announces itself, flexing under a loaded pot and ringing under the tap.
