This really is the best answer.Install laminate in bathrooms at your own risk. Excessive water will damage it. Even the Swiffer wet jet voids the warranty on some laminates. Just remember if you have a problem with it , it probably won't be covered under warranty.
We are not talking about a car salesman here....I would not install any laminate in a bathroom regardless of what any salesperson or Mfg stated
