About 18G 3218

A brass or zinc body under a plated finish — the finish is what you live with day to day, not the metal underneath it. Color family: Stainless. Finish is undermount.

We cut and polish the opening in the stone for it, set it, and reconnect the plumbing while we are already under your counter.

How it meets the countertop

The mount type decides what we cut, and what you see every day.

The sink goes under the counter, not on it. That puts the cut edge on show, so it is polished rather than left rough, and the weight is carried from below instead of by a rim resting on top. It is the reason an undermount kitchen has no line to wipe around.

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 36" — 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.

  • 32 1⁄8"×18"

Depth

Deep enough to stack a roasting pan out of sight and to run a tall pot under the faucet. Deep bowls also hide dishes, which is either the point or a habit you will acquire.

  • 9"

Questions about 18G 3218

Answered from this fixture’s own catalog attributes — nothing generic.

How does 18G 3218 mount?

It hangs under the counter. That is the version worth paying for if you wipe the counter more than you look at it: there is no rim in the way. It does commit you to a stone or solid-surface top, since the cutout edge is exposed and has to be finished. This one measures 32 1⁄8"×18" across and 9" deep, so it wants a 36" base cabinet.

What is 18G 3218 made of?

Stainless steel, 18 gauge. Practically: heatproof, rustproof, repairable with a scouring pad, and unbothered by anything a kitchen does to it except a cast-iron pan left sitting wet. Every stainless sink scratches; none of them fail. On a bowl this wide the gauge is doing real work — there is a lot of unsupported span under your hands, and it is the difference between a sink that feels solid and one that gives.
