I have a simple goal: I want to install a new vanity in my bathroom (in the United States, California specifically).
However, after extracting the prior vanity, I ended up having to cut some of the floor molding to accommodate for the size of the new vanity. Unfortunately, when I removed the piece of molding that I cut, I discovered it was hiding a 15cm wide, 4cm tall hole at the base of the drywall.
When I install the vanity, it will completely cover this hole. Assuming I mount the vanity right against the wall and caulk the joints, do I need to do any drywall repair to this hole or would I encounter any problems leaving it as-is?
