I decided to replace my Moen shower faucet (the cheap plastic-handle
kind my builder installed) with something a bit more fancy. I
purchased a new Moen Eva faucet with the same screw configuration as
the one I removed. I left the old posi-temp vale in-place as it is
only 4 years old and I didn't want to turn this into a huge job.

The new handle installs fine, but the handle sticks out about a good
inch or so from the wall-plate rather than mounting flush as it is
supposed to according to the picture and manual. Frankly, it looks
pretty goofy right now.

I looked at all the documentation and it looks like the valve is
supposed to be recessed further back in the wall. I'm not ready to rip
apart the bathroom wall and redo the plumbing.

Am I missing something? Is there an easy way to recess the valve
further back into the wall without ripping the wall open? Is there a
shorter cartridge option?

Thanks in advance!!
