Stainless steel can be found on just about every design element in the kitchen these days. On cabinets, it's typically formed around an inner core material to give it substance and keep it from sounding tinny. While you can get a very sleek look from stainless steel, it does show fingerprints and scratches.
A durable and sanitary material, stainless steel cabinets qualify as a "green product," as they are non-toxic, recyclable and easy to clean without the use of harsh chemicals. Stainless steel is also a top pick for people with chemical sensitivities.
As an added bonus, all-stainless cabinets are a great pick for outdoor kitchens, as they withstand the elements (humidity included) quite well.
Don't write off the stylish material as purely the stuff of modern spaces. Consider combining it with a Transitional cabinet, like a cherry Arts & Crafts-style door, for a tempered contemporary look.
Once you settle on stainless, you'll find there are a few other considerations to keep in mind. Many cabinets are made of the same material as professional-grade appliances; for a stainless look at a lower cost, investigate stainless cabinets with MDF/wood parts. A good number of companies can accommodate custom requests; if that's a particular need of yours, be sure to inquire about the manufacturer's custom capabilities from the get go.
To add a unique touch, consider alternatives to stainless steel. Copper moulding or brushed nickel finishes prevent a clinical feel, as does the occasional frosted glass insert.
