A recently renovated bathroom may look great, but if it was a DIY project by the Vendor, it's probably not to code and you will be stuck with seriously expensive issues. The shower in this photo actually had falls away from the drain and out under the bathroom door into the hallway. If they could not get the falls correct, what hope did they have of doing the waterproofing correctly. The failed water proofing will result in the entire bathroom requiring to be stripped back to bare walls, as leaking bathrooms can result in wood rot, mould and termite activity like shown in the photos below. The 3 photos below are from the same home, showing the termite damaged floor joists and bearers that the newly DIY renovated bathroom was hiding. Firstly the sub floor should have been replaced prior to the renovations. The power point should not be recessed behind the tiles, as this produces a moisture issue and makes fitting the snap on cover almost impossible to finish off nicely. Lastly the floor falls should be 1cm over 80cm, towards the drain in the shower area, it was actually raised and the highest point of the bathroom. To rectify the floor issue would require the entire floor to be removed, as would the issue with the termite damaged timber that requires replacement.
