The bowl that fits your biggest pan.
Bowl dimensions in — gallons, pan fit, and the NSF drainboard rule out, with the published bleach-dosing table underneath. All of it from Advance Tabco's own standards page.
What it holds
Capacity, pan fit, and the NSF drainboard rule settle the bowl. Advance Tabco's Build-a-Sink configurator turns the answer into a drawing — linked from their brand page.
Bleach sanitizing dose · per Advance Tabco's published table
Third compartment only, standard household bleach, test strips still rule the day — your health inspector reads the strip, not the chart.

Asked every week.
How many gallons does a sink compartment hold?
Advance Tabco's published working formula: length × width × depth in inches, divided by 321. A 24×24×14 bowl works out to about 25 gallons.
How big should a three-compartment sink's bowls be?
Big enough to submerge the largest thing you wash — a full sheet pan needs roughly a 27-inch bowl to lie flat. NSF also requires drainboards at least as wide as the smaller bowl dimension.
How much bleach sanitizes a sink compartment?
Per Advance Tabco's table: from 0.70 oz in a 10×14 bowl at 10 inches of water up to 3.60 oz in a 20×28 bowl at 12 inches. Verify with test strips — concentration, not volume, is what the inspection checks.
