I am ripping off my shower kit and the wall. Before demo, I took picture of the back of the shower fiberglass wall:
I plan to install tile. What happen next is to put drywall and then hardie board and seal.
My question is:
How to make sure the check valve mechanism flushed to the back and ensure the handle can screw in and flushed in the front of the tile?
So I assume I need to put the white piece behind the wall.
But old shower wall has different thickness which is much thinner than the new drywall + hardie backing board + thinset + tile which could be 1.5" thick.
I tried to "dry fit" everything first and need to figure out how this might look like or if I need to do some washer or different type of mechanism...
