Stainless steel and terrazzo (or marble) are the most common types of surface. It is important to consider how much use it will get and what type of stains or chemicals will be thrown on it. stainless steel is more resistant to corrosion, spills, scratches, chemicals but can show fingerprints easily. Terrazzo offers a smooth texture that resists many cleaners so installation needs to be done without grout lines so dirt doesn't hide in them but they require very high level of upkeep- they need to be sealed at least once every 2 years depending upon the location where it's being used.
