In response to Re: backer board
: I assume you will be using a mortar bed for the shower pan. You will want the mortar bed to be against the no more than 1/2" off the shower pan.

: : remodeling shower, (had shower pan leak) installing pvc shower pan liner. How close to the shower pan should the wonder board be installed.

There are actually two schools of thought: one suggests the backer be held above the actual shower floor with the gap filled with caulking; and the other as stated above with the backer embedded in the mud floor. I would do the second method.
