Floor tiles from scratch in PS. There are a few marble variations and some other random ones. Most of them are b&w so you can just use a RGB Curve or somthing on them to get color. There's a normal, displacment, and specular map. There's a grout map so you can change it's color seperately. Also the originals so you can make your own.
I just set up one in cycles to test out the displacement and normal maps. Went a little heavy on the displacement :) Did a few more renders with less displacement. The extras are inside the folder. If you like that shader you could just append and swap out the diffuse maps I guess or mix and overlay. Hope it's useful. Maps are 1024
