I always thought that it was a bit of a risk to put timber or floating floors in your kitchen simply because of the water damage risk, was told in the past that if you dripped even the slightest amount of water on them and left it (didn't notice it) then it could damage them.
I'm sure the product has improved a fair bit since then but I still prefer tiles for these reasons.
I think this is probably true for "naked" wood, but with all the laquer on top I doubt the water would even get to the wood. Can anyone shed some light on this?
