What it is
An open hole in the wall, exposed pipes and missing tiles hidden under a floating vanity.
Why it matters
In a wet area it's a path for water into the wall cavity, and it's unfinished work.
How we check it
We look under and behind every vanity with a torch.
The fix
Close up the wall, seal the penetrations and finish the tiling.
How common it is
We get down low in every bathroom, because that's where things get missed.
