tween hangout-bathroom

a friend and e-client of mine is busy finishing
 her walk-up attic space into a 

hangout room for her 
two tween daughters.

the space will include a large living area,

a half bath, a stage area and a study area.

here is the idea board 
i came up with
for the bathroom:

here is the plan:
anthropologie wallpaper on the ceiling,
crown molding painted black,
alternating stripes in several shades
of green and aqua on walls,
mirrored vanity with new aqua ceramic knobs,
marble octagonal tile floor with black grout,
black oval mirror flanked with sconces,
crystal chandelier,
small throw rug if needed...
it should be a FUN bathroom!
i am also working with this client
on the rest of the hangout spaces,
as well as a separate full bath and
guest bedroom, also part of the attic...
i will try to post my idea boards as i go!
