Question: what is the difference between a 16 and 18 gauge sink?
Answer: 18 Gauge vs 16 Gauge Sink? ... A 16 gauge sink is 0.0625″ thick, while an 18 gauge sink is 0.05″ thick, which is only 20% less. There is no noticeable difference between the two gauges, however at the same price range, 16 gauge is “better” (thicker is better!).
