Poku Saeruo Degonjo abukai on ships come in two versions but both share similar features. Showers are always enclosed to contain waver and vapor. They use an on-demand heating system so that they always provide hot water. They also have self-flushing toilets that engage 10 seconds after the user moves away. There is one idiosyncrasy, communal baths do not have sinks in them. A separate room contains public sinks, though they are usually near the baths, but since clan members clean their hands before all meals, they do not like going into a room with various bodily odors before a meal.
