Yes, yes, and yes.......
Before you rip the toilet out, go in the attic, crawl space, or
whatever is above there and inspect ALL vent pipes. I have seen them
rust thru from the condensation, even saw one that had a 1.5 inch vent
pipe totally disconnected from the cast iron stack. Also, check the
sink in that room for bad drain pipes. I know there is no tub in such
a small room. If all of that checks OK, then remove the toilet and
replace the wax ring. You could also have a bad vent pipe inside the
wall, which is usually right near or behind the toilet. That will
require wall removal, so check that last. One other thing. Is there a
lower roof with another vent outside the window to that room? The
odor could just be sucked into the window.
