Changed mine out but went to a plumbing supply store used by contractors to get a model close to the original. The new one sticks out into the shower about an inch farther though. The main problem I had was trying to use the old fittings (don't even try) save yourself some headaches. The new pex fittings and pipe worked perfectly. I did have to open up areas above and below the shower valve. Went to Tap Plastic for panels to cover the openings. It worked well and looks nice too.
