In some cases that ends with; "Then you should hire someone who knows how to do this correctly."
And that appears to already have happened.
@12string so why was the inspector there? You did the right thing and had a permit issued for your work?
Lets just say... by magic... my old home, the bathroom was gutted and remodeled... new; tile floor, tub/shower, toilet, vanity, lights, linen cabinets, wood trim, etc... Plumbing was moved for the single sink vanity (was 2 sinks). Outlets and switch locations, were moved and GFI outlets were installed (they were never in the bathroom before).
The county was on a need to know basis... and they didn't need to know.
