We recently went through a home tour of several new homes, and I was surprised at the number of metal and stainless steel kitchen cabinets I saw.
One very modern design had a mixture of black kitchen cabinets and metal cabinets. The kitchen was a black and white theme, and it did look very striking.
It really depends on the look you are hoping to achieve. If you want a modern, sophisticated look, metal kitchen cabinets really make a statement.
If you want something more traditional and casual looking, you would probably go with wood cabinets. When we had our house built, I had a hard time deciding on the color I wanted, so ordered unfinished kitchen cabinets.
When I finally decided on a color scheme, it was easy to treat the cabinets with the finish I wanted.
