help-vapor barrier in master bath

I removed the sheetrock on an exterior wall in my master bathroom and found that there was not a vapor barrier under the sheetrock. I will be installing Hardiboard on the wall for tiling. My question is should I have a vapor barrier on the inside of the wall under the Hardiboard and what is the best material for a vapor barrier? There is unfaced insulation between the studs.
