I wouldn' use laminate in the bathroom because of the amount of water. We have it in all 4 bedroom, living room & dinning room... and love it. Our daughter has allergies & it helps us to keep her undercontroll since the little things can't get stuck in it. Plus, w/ kids spills are so much easier to clean up!!!
We just use dishwasher soap & water to mop the floors. You can use other stuff also, I'm sure they would have more shine to them if we used something else, but the dishwasher soap is what we were told to use when our house tested pos for lead... guess it is the only thing that removed lead dust. So, we got in the habit of using it on the old floors (which had lead)and just keep using it just in cause. But it has been a few years & the house is still lead safe - which is a great thing.
Congratz on the new floors - I hope you like your as much as I love mine!
