1. Better ergonomic design. Products should be designed with the physical needs of the users in mind, not just the functions.
2. Accommodate a wider anthropometric range. Products should be designed for a larger age range — from children to grandparents. Too many products attempt a "one size fits all" approach.
3. Use of a systems approach. Products that are flexible can be changed to keep up with differing needs of a house.
4. Better surface treatment. Products that incorporate non-slip surfaces provide more safety.
5. Integration of other building systems. Products that use such features as additional lighting, electrical connections and storage add functionality to the bathroom. It increase safety too.
6. Better space planning. Interchangeable positions for plumbing fixtures and hardware support greater flexibility and accessibility.
7. Provide a choice of attractive styles and range of prices. Differing prices and style varieties (colors and materials) create more options for sales and profits.
