Looks like hardwood or engineered wood but it could be porcelain tile...they have some very good wood look tile out there.

The "look" appears to be Smoked White Oak or Smoked/Fumed European Oak. The planks are (roughly) 4" wide in a "Select or Better" cut.

Have fun.

SJ McCarthy , I agree but I think its vinyl made to look like wood.

closer to 8" wide

I am guessing either laminate or vinyl. Kronotex from Germany does many wide plank laminates BTW I have their flooring and it is awesome 3 huge dogs not one scratch in 12 yrs.

My favorite... pictures of wood on plastic! Oops, sorry! Was that my "out loud" voice?

That would be luxury plastic...
