Thanks in advance for any help.

Question: I am planning on having two 1/2 height walls surrounding a
44" Neo corner shower. Framless glass on top of the walls to the
ceiling and a door between the 1/2 height walls. I am wondering if the
walls have to be made with 2x4's. I ask this because I would like to
minimize the wall width.

Normal wall (from what I can see):
2x4 with 1/2" sheetrock on exterior and 1/2" Durlock/cement board on
inside with tile.

I would like to make the wall thinner. Can I trim the 2x4s or use
narrower wood? Will it affect strenght/integrity? Is there code on
this?

I will be using a Dix Systems pan liner for the shower.
