I am currently renovating my bathroom due to loose tiles that were placed on top of drywall that is now moldy and falling apart. I have torn out all of the tiles & walls from around the bathtub and want to replace it with a waterproof barrier and cement board.

The issue that I have run into is that the cement board is 1/8" thinner than the drywall that is around the rest of the bathroom. I have not tried to put the cement board up yet because I have been trying to find a solution to this problem (i.e. 1/8" shims or someone who can give me advice on how to remedy the situation).

I was looking at ideas on youtube yesterday and came across a new type of backer called Fiberock Tile Backerboard. It is waterproof, and can be tiled or painted. I was considering removing all of the walls in my bathroom and putting this up instead so that I can tile around the bathtub and just paint the rest, and not worry about a transition point between the cement board & green board. Does anyone have any experience with this product, or any advice on the 1/8" difference in wall thickness? (The rest of the walls in the bathroom have old wallpaper that has been painted on top of, so I wouldn't mind removing the rest of the walls just to get rid of the ugly bubbles & ripples in the painted-over wallpaper.)

If it were me (and I have done what you're looking to do), I'd tear out everything down to the studs. Why do half a job??

that would be your call. the backer board would cost you over twice as much as drywall. i would shim the 1/8 inch. don't forget to waterproof either behind or over top of the cement board.

Shim out the area with "butt shims" (drywall shims, furring strips). They are available at H.D. in the drywall department. These strips are 1/16" thick, so you may need two to achieve the proper thickness.
