Water is not good for any wood. If solid wood or engineered wood gets wet it is not a good thing. But, just the relative humidity in you home will not bother the glues in engineered any more than it does in solid. Relative humidity in a home is normally between 45% and 55%. Unless in the spring and fall you have you windows open where then it may go as high as 65%. If you spill water on a wood floor get it up right away. If the dishwasher, ice maker, sink, etc. leaks call your insurance company. Make sure your insurance company knows that you have hardwood. Some require a rider on the policy to cover hardwood floors.
