IntroductionIntroduction
Universal design is a commitment to designing for all people
Therefore universal design of residential bathrooms should benefit all people living in a home
But they do not support all users equally, and while their designs may improve the functional independence of some people, others experience functional deprivation
These days independent use of the bathroom is very important for all users

• The Independent Living movement Everyone wants to be independent in the bathroom
[ In 1900 ]
• Life expectancy was 44 • Assistance in the bathroom did
not become a factor of the early design
• The concept of early bathroom design centered on independent use and use in complete privacy
Bathroom users today are vastly different from the users when the bathroom first originated

Bathroom Research & Design Bathroom Research & Design GuidelinesGuidelines The Center for Inclusive Design and Environmental
Access(IDEA) conducted bathroom study “Listening to People”
Listening to People• Interviewed 30 consumers about bathroom use and bathroom
products
(Independent users, dependent users, care providers of different ages, sexes, races, and physical conditions)
• Examined the need, importance, and benefits of universal design in the bathroom
• Doors, Grooming Area, Toilet Area, Bath and Shower Area, Safety, Usability, Appearance, Personalization
