Thanks for checking it out! This particular floor none is needed, it is partially water resistant where you don’t need an additional finish. If you are worried about high humidity areas I would recommend vinyl plank floors. We did that in our bathroom because it is 100% waterproof.
That floor right there is vinyl. It looks very similar to laminate except it’s made from plastic where laminate is made from wood. If you put a floor that is susceptible to water damage it will warp the boards quickly I realized the hard way.
