Bathroom Renovation Advice

We recently discovered black mold on the backside of the drywall that is behind the toilet of our bedroom bathroom (it shares a wall with hall bath and there is a small access panel). Since the bathroom is very small, I thought it might be a good place to accrue some DIY skills. Going in we thought we could either replace the affected tile/drywall or do a full gut/remodel to update the space. As expected, we've ran into some curveballs (to us) and are looking for general thoughts and advice for the process. Once we removed some of the tile and the built-in vanity, we realized there's a good 1" mortar base on the wall and directly on the slab foundation (Where the vanity was built there is just the slab). With this in mind just tearing out the affected drywall and patching everything up seems less like the right path, and we are leaning towards a full reno. In regard to what caused the mold, we discovered the toilet drain pipe has a crack a couple inches down and we believe water was leaking through that and then in-between the slab and tile mortar base. We obviously plan to fix that. General info: House was built in 1959 We have PPE (Respirators, eye protection, gloves) Loose timeline My concerns: 1" mortar base removal on all walls and floor The shower demo/reno in general Asking for: General advice on the process! submitted by /u/ManDogBlackedOut [link] [comments]
