Had a bathroom extension built and I asked for an unswitched fused spur to be fitted so I could locate the tumble drier in the bathroom. Subsequently decided not to locate the drier in the bathroom but the lecky fitted an unswitched three pin socket run from the original electric shower feed (not used now) which has of course a switch but is mounted outside the bathroom. He did change the breaker in the consumer unit to the correct rating for the socket. I always though it was not within the regs to fit a three pin socket in a bathroom or am I out of date with this now?

"The 17th Edition introduced another important change: Regulation 701.512.3 permits 230 V socket outlets to be installed in a room containing a bath or shower, providing they are installed 3m horizontally from the boundary of zone 1"

If I take Zone 1 to be the shower basin then my installation certainly breaks the 3 metre horizontal rule by miles as its only around a metre!!!

Sounds like your electrician bent the rules a little to give you exactly what you asked for. I say give the man a medal!

If the socket isn't needed then remove it. Get a small bit of plasterboard to fill the hole - job done. Done this with disused sockets and light switches several times and once filled and painted (or tiled) you'd never know.

Just fit an RCBO in the consumer unit.
