I was thinking off going under the floor, it's disturbing the tiles when going up that worries me unless the misses decides she wants new tiles as now "she doesn't like them"

, which by all means would be the better option. Am I correct in saying wires under the floor in a bathroom are fine to run providing they have adequate cover from water?
Fishing I've never done unless it involves a lure, I got a wire/current detector laying around somewhere. Bathroom is just over 3m long.
Thanks for the heads up, I know the box you speak off now, not clued up on wording to much. Like recently I knew what rebar was just didn't know what it was called
