Countertops are as important as cabinets and floors when one is planning a kitchen design. They could very well be the more expensive part of a kitchen. Before you choose a kitchen countertop you should educate yourself about the quality as well as know how best to maintain the product you chose. Although, Price is often a driving factor, aesthetics are often the deciding factors in most design choices. People want their kitchens to look beautiful and will choose a countertop that best serves that purpose.
A countertop is basically a solid surface that you can use in the kitchen or bathroom. Because of this there is a lot that you can get away with from solid surfaces that are concrete made to look like marble or granite. When designing a kitchen, the Countertop is important mainly because you need it to place things on and work from. So it needs to be as solid and hard as possible. It also needs to handle heat.
Concrete Counter top
Concrete is popularly used as a kitchen countertop but there are other types of countertops that one can choose from. The difference is always in the design that has gone into the concrete countertop. When you say: "concrete" most people think of a more outdoors, rough look. That is only a basic idea of what concrete itself as a material is but, as a countertop it can be made to look like the most expensive stone countertop.
Stainless Steel countertop
For a more restaurant kitchen look, then you would want to consider a stainless steel Countertop. Stainless steel might be better suited to restaurant use because you can spill and put mostly anything on it without really doing much damage to it. It doesn't however look so good as part of a more traditional woodsy kitchen design. Stainless Steel is used in more contemporary kitchen designs.
Wooden Countertops
Wooden surfaces offer a more traditional look. They are popular in traditional kitchens, as popular as the butcher-block perhaps is in most farm-style kitchens. Hard words like maple and oak are often used to give kitchen tables an instant antique look. The problem with wood however is that it stains quiet easily and ages with use. To maintain the surface, most people sand the scratches and stains out and then reseal the surface.
The point of the matter is, whatever material you choose on your countertop, it needs to fit your the look and aesthetically fit into the complete design of a room and the overall lifestyle.
