I'm installing laminate flooring an a bedroom adjacent to the bathroom.
The transition strip to the vinyl is made of the same stuff.
I'd like to keep accidental water spills outa the laminate.
I thought about running a thin layer of caulk along the
edge of the laminate, but not touching the floor, under the transition
strip. to seal it off.
But ordinary caulk is water based???
Can the cure be worse than the potential of water spills?

What's the recommended treatment at the joint between laminate
in the bedroom and vinyl in the bathroom?
Thanks, mike

An accidental spill of water can be dried and handled right away.

If something breaks and floods the bathroom, while sleeping or on
vacation -- caulk won't help. Some portions of the flooring will/may
need to be replaced. That depends on the extent of the damage.

Don't worry about it until it happens.
