I'm at the point in a bathroom remodel where I'm gonna hang the walls
for a half-bath, that is, an enclosed shower. I live in Albuquerque,
where the relative humidity is usually near 20%, so a lot of the things
that happen in other places simply don't happen here.

The shower will be enclosed with tile. My question is whether treated
drywall will be alright as a subsurface, or will I live to regret
wanting to go that way? I find drywall easier to work with than
hardibacker, as well as cheaper.

What do you think?

Happy Holiday.
