Humidity is the material test here
An outdoor kitchen on the Gulf Coast lives through months of high humidity, and that is what decides how it looks in year ten. Stainless steel is not one material — 304 resists corrosion far better than the 430 common in cheaper appliances and doors, and the difference shows up first as rust freckling around fasteners and hinges. The structure behind the finish matters as much: a carcass framed in galvanised steel with cement board behind the stone behaves very differently from wood in this climate. None of that is visible on the day it is installed, which is exactly why it belongs in the specification rather than in a conversation later.
