We all use bathrooms--probably without thinking too much about them. It's surprisingly interesting to spend a few moments contemplating the shape of the fixtures.
My favorite discovery was probably included more as a throwaway, a space filler. In the back room there are four displays showcasing designs by four different designers. While bathroom fixtures are the primary focus of those exhibits, each one also includes at least one non-bathroom object also created by the designer -- these objects are included to highlight the designers' talents and flexibility in other areas of design. One case holds a citrus juicer with a placard describing the juicer as the creation that sparked "the citrus juicer controversy in the '90s." Sorry to say I missed that whole debate!
Bottom Line: Worth a visit, if only to see that funky juicer and imagine the fuss it sparked in certain circles.
