Basement Bathroom Insulation/Vapor Barrier
 

Seems like lots of different opinions on this question. Would greatly appreciate any help.

Situation: Renovating existing basement bathroom. Have demo-ed down to the studs. One wall (where half of new corner shower kit will be) is framed against below-grade cinderblock foundation, other walls are interior basement. Only tile will be on the floor, walls will be mold-resistant drywall. There will be a vent in the ceiling.

Question: Should I insulate any of the walls? Should I use faced insulation? Should I use a separate vapor barrier? If yes, should the vapor barriers be facing out or in?

Thanks in advance.

Insulate between studs and bearier on inside to keep moisture away from framing
