Hold off on setting the toilet and the baseboard molding until you’ve filled the expansion gaps around room perimeters and the toilet flange with 100 percent silicone caulk.
How to Seal Laminate Flooring
Anytime you install laminate flooring in a bath, laundry room or kitchen, you should use AC3-rated flooring, leave 1/4-in. expansion gaps at the walls and fixtures, and then fill the gaps at flooring ends with 100 percent silicone caulk. It stays flexible, allowing the floor to expand, and in the event of a spill, prevents water from soaking into the laminate core. Filling the gaps can use up a lot of caulk, so buy more than you think you’ll need.
