Sometimes a plumbing job starts simple… and then turns into a full shower valve and bathtub spout replacement.
This homeowner called us saying, “My shower handle is leaking, can you swap the cartridge?” No problem – 80% of the time it is just a worn-out cartridge. Quick job, in and out.
But when we removed the trim, it was clear this was not going to be one of those quick jobs. The entire shower valve body was completely rusted, corroded, and basically falling apart. The cartridge wasn’t sitting tight anymore, and even a brand-new cartridge couldn’t seal it. Same story with the bathtub spout – everything was old, brittle, and way beyond repair.
Once a valve body is destroyed like that, there’s only one correct solution: full replacement of the shower valve + bathtub spout – not a band-aid “cartridge” fix that will fail again in a few weeks.
The hardest part?
Normally we open the drywall from the other side of the bathroom to get full access. But in this house, the back side of the shower was the exterior wall, which means zero access. So the only option was to carefully open the tile from the front – just enough to work without destroying the entire shower wall.
We cut the old valves out, cleaned and prepped all copper lines, and rebuilt the whole setup. Used soldering where it made sense, and RIDGID ProPress https://www.ridgid.com/ where it saves time and gives a cleaner connection. Every joint passed pressure testing on the first try.
Once everything was done, we installed a clean cover plate (escutcheon) to hide the tile opening. It looks tight, professional, and blends perfectly with the shower. The customer was honestly shocked how clean the result came out.
And yes – we installed a Moen https://www.moen.com/shower valve system with a lifetime manufacturer warranty. That’s why we use Moen: you install it once, and you’re done. No callbacks in 2–3 years, no cheap builder-grade junk. Just a strong, reliable valve that actually lasts.
Now both the shower and bathtub work perfectly – no leaks, smooth handles, steady pressure, and a clean professional finish.

Can I replace a shower cartridge myself?
You can, but most stuck cartridges don’t come out clean. When you start pulling it, the valve body can crack or twist inside the wall – and then it turns into a full valve replacement. If it feels tight or stuck, stop and call a plumber.
Can I replace the bathtub spout myself?
Sometimes you can, but many tub spouts sit on an old, corroded copper stub-out. If you twist it too hard, you can break the pipe inside the wall and flood the bathroom. Easy job turns into drywall + plumbing repair real fast.
Can you install a cover plate after replacing a shower valve?
Yes, in most cases a cover plate works perfectly. It hides the opening after we change the valve, and you don’t need to redo tile or open the whole wall. Clean, safe, and way cheaper than a tile repair.
