I always take my tile approx. 5-6mm into the casing where the door closes. Hopefully the floor covering on the other side also goes into the casing by at least that much. That way when the new threshold bar is fitted it actually sits underneath the door, in its rightful position and covers both floor coverings.
One of my pet hates is seeing door bars standing proud into a room!!!
