The Fofinor Abukai are used by members of the Poku Saeruo Degonjo for the obvious purpose.
With the exception of private quarters, the only rooms used for washing hands are the hapu abukai. They typically have six basins with faucets, soap dispenser. Hot water is supplied by on-demand heaters. Located between each pair of basins is a hand drier. There are four standard lamps on the ceiling. The floor is covered in tile, with underfloor heating for comfort.
