Are there free/cheap shower facilities at Bali Ngurah Rai (Denpasar) airport's international departure terminal? The official website doesn't mention any, other websites mention only lounges which cost ~$35+ per person. Some individual traveller's blogs mention free showers hidden behind the toilets, but it's unclear how current this information is.
Can somebody confirm which of these facts are true?
Since our flight leaves at midnight and we'll be sweating the entire day before, it'd be nice to have a quick shower before takeoff without going broke.
