Vapor barrier in bathroom ?

Re-doing a basement bathroom and want to tile to shower stall. I have the Hardi Backerboard and have insulated the walls with R-19.

Do I need a vapor barrier over the insulation prior to installing the Hardi?

I would not use a vapor barrier behind the hardi. I would apply redguard to the hardi.
