FWIW, we're getting ready to do several rooms worth of insurance-covered floor covering work due to a plumbing disaster that happened while we were away for a few days (Murphy's law strikes again). Wife wanted wood, but I didn't like that idea because it's all high wear areas and is going down directly over concrete. After looking over what's available for water/damp resistant flooring in our very high traffic kitchen/breakfast nook/mud room area, we've settled on random-laid 3-1/2" x 24" wood-grain finish 3/8" thick porcelain ceramic tiles. I didn't even know they made this stuff. We looked at several sample floors done with this stuff, really liked the look, and it's practically indestructible as far as wear and moisture go. Comes in several kinds of wood grains and colors, and runs around $4 per sq/ft, not much more than good laminate, although a pro installer is needed so labor is higher. These will be going down directly on a concrete slab. Our tile contractor thinks wood plank look porcelain tiles are a great idea, says they are hands-down more preferable than laminate or solid wood if the flooring is going directly onto concrete, and his customers love them. They also come in wide planks, too, but we liked the look of the narrow version. We'll see how they work for us.
For concrete slab floors on or below grade, this stuff might be worth a look before you commit to any type of "floating" laminate or wood flooring that has to be put down over a moisture barrier and refinished every few years.
