Abstract
Rapid ageing in Japan raised questions whether the washbasin height was still valid. Preliminary observation revealed that existing height was lower than acceptable. Experiment was conducted to examine the preferred height of both spout and bowl during face wash. Senior subjects were asked to wash their face without any imposed conditions, and preferred height was determined. Spout height ranged between 810 mm and 960 mm, with an average of 890 mm, much higher than existing spout. Observation of posture identified two types, i.e., some moved up and down their hands, while others moved their face. Preferred height of the bowl ranged between 675 mm and 875 mm, with an average of 771 mm. It was also higher than commercially available standard designs.
