Should I add grab bar to remodeled bathroom?

[Deb L.]

I'm having our first floor condo master bath remodeled.  Should I add a grab bar?    The demographic is typically 30's-40's, some younger since it is close to a college.  It' a whole lot easier to add one now than later.   And would it have to be installed by another type of specialist rather than our contractor (due to liability/ADA considerations)?

Thanks.
