Nope. Laminate is water-resistant, but it’s not entirely waterproof. Laminate flooring cannot reject 100 percent of water, despite what a laminate brand might claim.
The core of laminate flooring is made from fiberboard. When it comes in contact with water, it can bubble up and crumble. The joining system on laminate is also vulnerable to water.
Not only do you want to avoid installing laminate in high-humidity areas, like a bathroom. But you also want to limit cleaning it with too much water. Always dry your laminate flooring after mopping or spot-treating stains.
