If it's not too late, take a hard look at luxury vinyl planking
(LVP
). It's much more stable than laminate and the rigid core or EVP is usually thick enough to span imperfections in your subfloor with out an new underlayment or foam pad. You can still get a great wood look and most products out there can be submerged in water and don't shrink/contract. It's a bit more $$ per s.f. but you won't have to worry about the humidity changes. You still need to leave an expansion joint on the outside edge but I think that's just a CYA from the manufacturers. Run your base over the top and if you want add 1/4 round to finish it off--just don't nail in the floor!
We own a flooring store and laminate has all but been replaced by these "LVP or EVP" products. A little more can be read here:
