The VitrA Sento Kids Collection focuses on toilet use at two age milestones in the personal development of children: three to five and five to six years of age. Age, sex, height, weight, and knee heights of children between the ages of three to five and five to six were taken into account as their toilet behaviors were observed. The color palette of the Sento Kids Collection was chosen to encourage children to see the bathroom as a safe and friendly environment. The Sento Kids Collection offers great design versatility by combining a choice of colors and dimensions as well as heights for different age groups.
