18G 50/50 - 3118 is an 18-gauge stainless steel double-bowl kitchen sink, about 32.3 by 18.5 inches and 8 inches deep. The two bowls are equal, which suits washing on one side and draining on the other. It clamps beneath the stone so you can wipe the counter straight into the bowl, which needs a polished cutout.
About 18G 50/50 - 3118
A brass or zinc body under a plated finish — the finish is what you live with day to day, not the metal underneath it. It reads Stainless. It comes undermount.
Undermount openings are cut and polished in our shop off the template, not freehanded in your kitchen. It is one of 8 colors we stock from the Double Bowl Kitchen Sinks range.

How it meets the countertop
The mount type decides what we cut, and what you see every day.
It mounts under the countertop. Practically that means we cut the opening to the bowl and polish the exposed edge — an undermount leaves the stone itself as the visible border, so that edge is finish work, not a rough cut hidden under a rim. The payoff is the one everybody notices: you can wipe the counter straight into the sink.

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 1⁄4"x18 1⁄2"
Two bowls
Split into two bowls, so the dimension above is the outside of the pair rather than the space you get for one pan. That is the whole argument between one bowl and two — a divider buys you separation and costs you the ability to lay a baking sheet flat.

Questions about 18G 50/50 - 3118
Answered from this fixture’s own catalog attributes — nothing generic.
How does 18G 50/50 - 3118 mount?
Undermount. The bowl hangs below the countertop and no rim breaks the deck, so crumbs go straight over the edge instead of catching on a lip. The counter carries the weight, which is why this style wants a fabricated stone top — we polish the cutout and clip the sink to the underside as part of the same job. This one measures 32 1⁄4"x18 1⁄2" across, so it wants a 36" base cabinet.
How many bowls does 18G 50/50 - 3118 have?
A pair of equal bowls. It is the classic split, and it is genuinely good at the job it was designed for: soaking on one side, rinsing on the other. Roasting pans are the thing it will not swallow. The pair measures 32 1⁄4"x18 1⁄2" across, so it wants a 36" base cabinet.
What is 18G 50/50 - 3118 made of?
Formed stainless — 18 gauge stock. It is the pragmatic choice rather than the decorative one, and it is what most of these sinks are for a reason: it is the only material here that shrugs off both a dropped bottle and a boiling pot. 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.
