I purchased a slant wall shower pan from a Jazz Sales dealer, but I did not purchase the already made walls.

I'm finally to that point of my conversion and I'm struggling with the design of the wall which is free standing (the third wall - about 22" long). What should I use to frame it?

Any plans/suggestions or pictures from people who have done this would be greatly appreciated.

If all else fails, I may just call and order this one specific wall.
