If you haven't seen any wet spots then it's probably not an issue.

Jason Curfman I’m a realtor in raleigh and starting to get my feet wet with personal Rei in the area.

Wet cut makes running mud. 

Again, watch few auctions before you get your foot wet.

If you can use Shark Bites or do basic copper pipe sweating, you can also dig into the wet wall easily, rip out the Moen valve, spout, and head, and hang a shower tower in that bathroom.

You may want to pay up for that if you can get it in concrete because painted concrete can be slipperty when wet.

I called a plumber since while I had a 20 foot snake and had an idea that the clog was there and not somewhere else since I carpeted over another drain in the basement and it wasn't wet over there and I know the layout of the sewage pipes, I I couldn't get the cleanout cap off for the life of me, and I had a pipe wrench, and using my 200+lb bodyweight LOL. 

If this is your first rental period and you want to get your feet wet. 

Wet mop the whole slab with bleach water.

Sometimes it looks like crap when it's in that weird semi-wet stage.
