When Does SUS316 Actually Make Sense Instead of SUS304 for a Kitchen Sink?
SUS316 is more corrosion-resistant than SUS304 — but that does not mean every kitchen sink should be made from 316.

A 30-inch sink is not necessarily a 30-inch bowl. Two kitchen sinks can have exactly the same outside dimensions and still provide noticeably different usable space. The difference comes from how much of the overall footprint is actually converted into bowl volume. Key factors include: For buyers, the more useful comparison is not: “Are both […]
Why Can a Deep Kitchen Sink Create Drain or Garbage Disposal Clearance Problems?
