Drop-In Sinks & Sink Bowls
A drop-in sink (or weld-in sink bowl) is a stainless sink bowl that sets into a cutout in a bar, prep, or equipment-stand countertop instead of coming as a whole freestanding sink. It's how you add a hand sink, dump sink, or prep bowl to a run of counter or a custom fabrication. Choose the bowl size (opening and depth) for what you'll wash or drain and to fit the cutout your top can take, then the gauge — 16-gauge for heavy bar and prep duty, 18–20 for lighter use. Confirm whether it includes a faucet and drain, and that a hand sink you drop in still meets your local handwashing requirements.
Compare commercial drop-in and weld-in sink bowls across brands by bowl size, gauge, and price. Filter to the cutout you're building. Where a spec (mount, compartments, exact bowl depth) isn't published we leave it blank rather than guess.
Drop-in sinks: buying guide
A drop-in sink bowl sets into a counter cutout instead of coming as a whole sink. The 103 models above filter by bowl size, gauge, and price.
Size the bowl and the cutout
Pick the bowl opening and depth for what you'll wash or drain, and confirm the cutout your countertop or equipment stand can take without losing rigidity.
Gauge
16-gauge suits heavy bar and prep duty; 18–20-ga is fine for lighter hand-sink or dump-sink bowls.
Check what's included
Confirm whether the bowl ships with a faucet and drain, and if you're dropping in a hand sink, that it still meets your local handwashing requirements.

Frequently asked questions
What is a drop-in sink used for?
It's a stainless bowl that drops into a counter cutout to add a hand sink, dump sink, or prep bowl to a bar, prep line, or custom equipment stand — without buying a whole freestanding sink.
What gauge should a drop-in sink be?
16-gauge for heavy bar and prep use, 18–20-gauge for lighter-duty hand or dump-sink bowls. Lower gauge is thicker and more dent-resistant.
Does a drop-in sink include a faucet?
Some do, most don't — confirm whether the bowl ships with a faucet and drain, and buy the faucet with the right center spread for the bowl's punched holes if not.
Where do your specs and prices come from?
Specifications are compiled from manufacturer spec sheets and authorized dealer listings; where a value isn’t published we leave it blank rather than guess. “Street price” is the lowest legitimate published price from an online dealer we track for that exact model — equipment only, and it changes often. Many models here have no published online price and show “check dealer pricing.”
Does this equipment need to be NSF listed?
Storage and dish-room equipment used in a commercial kitchen is generally expected to be NSF/ANSI listed for cleanable, food-safe construction — that’s what a health inspector checks on plan review. We don’t assert a listing for a specific model unless the manufacturer publishes it; confirm the exact model’s listing when you permit your kitchen.
About this data
Last verified: August 2026. Specs are compiled from manufacturer spec sheets and authorized dealer listings; where a value isn't published we leave it blank rather than guess.
Methodology: every drop-in sink model is compared on the same set of specifications, and dimensions are checked (for sinks, overall width must exceed the combined bowl widths) — figures that fail validation are corrected from the manufacturer model number or omitted. “Street price” is the lowest legitimate published price we've found and can change.
Sourcing: product specs come from the manufacturer; regulatory statements link to the source (e.g. the FDA Food Code and NSF). Code requirements vary by jurisdiction — confirm with the authority reviewing your plans.
