Rather than laminate flooring check for "engineered hardwood"... at least that's the term used here in the U.S. A thin layer of any variety of hardwood is pressure glued to a thicker base of real wood than that used for laminate. Even using laminate, if you would run a thin bead of common carpenter's glue (the glue not the carpenter) on each seam just before snapping together will improve the water resistance. Same holds true of the edges... just a bead of the white glue will improve the products resistance greatly. Keep a supply of damp cloths nearby to wipe off excess glue as you lay it... don't let it dry, else you'll have a mess...
