You will probably have either have a suspended timber floor or a solid concrete floor. How will you cover it. There's vinyl tiles, heavy duty continuous vinyl, ceramic tiles, carpet and lots of other materials. I used to have vinyl tiles and yes they do the job, easy to clean and water spills aren't a major disaster.
When they started to look shabby, I opted to lay ceramic tiles. Major cash outlay, but they don't show any sign of wear, they are easy to clean, I can push buckets across them without doing any damage and water won't do any harm.
You can go for commercial carpet. It looks smarter (when it's new!) but you'll most likely have to opt for a darker shade to hide the inevitable stains, and any water spills will be a headache.
