The answer is No, laminate flooring isn’t waterproof. There is a common misperception out there that laminate is waterproof and many homeowners confuse between vinyl and laminate flooring.
Many types of vinyl flooring are waterproof or are water resistant. Laminate, however, is made out of recycled hardwood, so it isn’t waterproof. If someone tells you about waterproof floating floor, don’t believe them right away.
