Are you looking for it to be a Vue Procedural material, or image-based?

Whenever I do Vue-based materials, it's with the expectation that I'll be going over them like crazy in Photoshop. I have much better luck just making my materials in Photoshop as large TIFs (Color, Bump, and Displacement) and apply accordingly. They look more realistic as well.

Need some TIFs?
If you want a fantastic starting point, go to www.cgtextures.com and look through their floors and tiles sections.

Hope this helps-
