Steve is correct in his definition of Bathroom, but the 2009 IRC wasn't applicable 15 years ago. It hadn't been written yet. What was the code then? I wouldn't call out stuff like that. If it had an outlet that wasn't GFCI, I'd point that out; but no outlet at all? Which makes me wonder what possible use you would have for an outlet in a tiny room meant only to relieve yourself and wash your hands. I'd be more concerned that it had an exhaust fan. Would you shave, blow-dry your hair, trim your mustache, run your curling iron, or just charge your phone?
