We looked into adding insulation to the garage, but I didn't want to deal with them having to remove the existing batt insulation to install spray foam insulation, so we haven't done anything. You could look into baseboard heaters for the room over the garage in the winter.
Have you thought of installing underfloor heating? That was one of the things on my wish list that we didn't do when they built the bathroom. I found a system that you could install in the rafters without tearing up the floor. Unfortunately thats probably last on our list of stuff to do.
