You would also have to be sure the slab was poured extremely level. Any variance more than 1/4" does not promote successful laminate flooring installation. I would price the sheet flooring that looks like wood/laminate. The hairdresser here in town had that recently installed and it looks fabulous. Of course, you would probably need to pay labor to have someone install it, but they could also use a leveling agent to smooth the floor if need be--not sure how much variance the sheet flooring can take. Good luck! (Oh, and if you do go for laminate, it is not recommended for wet areas (entryway), however, I do have it in my laundry area in the basement and am not the least bit concerned. Also, buy the best quality foam underlayment you can afford, it makes the walking on the floor more acoustically appealing.
