Hello all please excuse my ignorance.
When putting in a shower pan, should the cement board go behind the flange or over it.

when putting in a tile floor, should the shower pan also sit on the cement board, just or the sub floor.

thank you in advance.

Cement board over the flange.

Receptor can sit on the sub-floor or the cement board, it's easier to do it on the sub-floor.

We frame our walls tight to the pan. Set the backer board on top of the flange. That way you need not fir out the walls to match the pan or have a wall that bevels at the pan. You can fill the gap at the flange with thinset

The pan sits on the sub floor. The tile backer abuts the face of the pan.
