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 (and I'm not sure if this is even feasible.

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 I can buy?

Thanks in advance!!
