Need advice on closet wall behind shower

I have a closet that is directly behind a shower/bathtub. It is showing signs of mold. Should I replace the drywall and check for leaks in the plumbing. There is no access to the plumbing. Thank you

Welcome to the forums.

Most definitely. You are lucky you have a closet behind the shower.

Right... there is no actual access to the plumbing. Removing the sheetrock is the only way.
You should carefully mark out the section you need access to and remove the sheetrock from between two wall studs. You should only need one section open from floor to ceiling for inspection.

You can trim the sheetrock so that half the stud is exposed on both sides and that will give you a place to screw in the new sheetrock. If you cut down the center of both studs from the start.... you may be able to reuse the old piece of rock.

You should determine the cause of the mold. As you suspect, it has something to do with the shower. You can cut a hole in the drywall or remove a section of it. You will need to be able to see what is going on with the plumbing. Is it the wall that backs up to the shower's faucet? One option is to use an inspection camera....this will let you see a lot without having to remove a lot of the drywall. It is possible that the leak has something to do with the shower valve, or grout, or caulking leak which can be fixed from the shower side and require only minimal drywall removal on the closet side.
