Compare 16 and 18 gauge sink options by checking thickness in millimeters, measurement points, bowl construction and sound dampening.
Under the same stainless sheet gauge convention, 16 gauge indicates thicker nominal sheet than 18 gauge. When comparing quotes, ask for the nominal thickness in millimeters and confirm exactly where it applies.
What should the quotation specify?
Ask for the stainless grade, nominal starting sheet thickness and tolerance. Agree on measurement points for sample approval. On drawn bowls, measurements at different points of the finished bowl may differ from the starting sheet specification.
Compare like-for-like samples
For applications with frequent heavy cookware use, consider trialing the thicker option. For volume orders, an 18 gauge option can also be evaluated alongside bowl geometry, mounting support and sound-dampening pads. Use the same size and installation conditions to compare samples.
Browse sink models, then use the same specification sheet to confirm thickness and configuration for each quote.
