But they are also entirely consistent with the design philosophy that runs through all of Kenner’s work.

The back washer addresses a problem that anyone who has tried to wash their own back thoroughly knows: the difficulty of reaching all parts of the back with a regular washcloth.

Most people solve this problem by accepting incomplete cleaning, by using a long-handled brush or loofah, or by asking someone else for help.

For people who live alone, or who have limited shoulder mobility, or who simply prefer to be self-sufficient, the incomplete solutions are frustrating.

Kenner’s mounted washcloth holder — attached to the shower wall, moistened, and usable without requiring the flexibility that reaching across one’s own back demands — is a practical solution to a practical problem.
