We have decided to make grab bars a standard in bathrooms.
Until you ask us nicely to remove the grab bars, we will include them in your bathroom design. This morning we gathered round the building code and chatted about the importance of grab bars and how they add an element of safety to bath tubs and showers.
Moen makes some pretty acceptable looking products that would look as natural in a newly designed bathroom as the towel bars that it coordinates with. See the Moen Align or Arris for examples of design-conscious grab bars.
Though you might not be slipping now, you may find yourself wishing you had something to grab in the future.
