Note also that when making any changes to an electrical system, one must also ensure that the main equipotential bonding is brought up to current requirements.
See Earthing and Bonding for more detail. One fundamental requirement for any electrical equipment be it an appliance or an accessory such as a switch is that it should be suitable for the location. This means one needs to apply some common sense when choosing and installing equipment. Ordinary electrical light switches are sometimes permitted in a bathroom, however one should only use them where there is no possibility that someone could operate them from the bath or shower.
They also should not be in locations where they are likely to get splashed or have excess steam or vapour directed at them. Traditionally, pull switches are used to mitigate some of these risks.
Common alternatives include using conventional switches located outside of the room. Switches will also be required for other devices like heaters or towel rails. Some may be intended for day to day use i. Again, the type of switch selected will depend on where it is going, as well as when you anticipate it being used. Note that the above zone concepts also apply to lighting in a bathroom.
Hence in many cases lighting will need to be specifically designed for the location and be IPX4 rated or better. In larger bathrooms where lighting can be installed outside the zones then one still needs to use common sense in the selection of fittings. Although conventional mains lamp fittings may be appropriate in large rooms where there is little steam generated typically those with no shower , they would be a poor choice in many cases. Illuminated mirrors are often be placed direct;y above a basin, and in a bathroom this may count as zone 2 unless the light fitting is at least 60cm clear of the taps.
Historically, 13A general purpose mains sockets have not been permitted in bathrooms at all. The 17th edition has introduced a slight relaxation of this, but it will only apply for very large bathrooms since it permits a socket to be installed as long as it is at least 3m from the outer edge of zone 2.
Shaver sockets are permitted in zone 2, but only if they are of the isolating type with integral transformer. Electrical equipment in a bathroom will generally need to be via a permanent "hard wired" connection.
Typically to a cable outlet unit switched or otherwise , or a fused spur unit again, switched or otherwise. If an electrical appliance requires external functional switching i. Ducted fans are typically installed outside of the room and are hence not subject to any special rules.
Extractors will frequently be powered from a lighting circuit - especially if the fan it to be integrated with operation of the light switch often with a "run on" timer.

Switched spur in bathroom Thread starter screech Start date Jul 13, Tags don't outside shower switch zones Copy link Copy link.
Guys, I need to settle an argument with a colleague with the location of a towel rail spur As per table and fig 8. I understand sockets need to be 3m from the bath or shower, to allow for the flex Reaction score 10, If you've got the OSG how is there an argument mate? Are sockets allowed in a bathroom then! Surely that just applies to 'A room containing a shower'. Don't think I'd be putting a socket in a bathroom for anyone.
But to the original question, from memory as long as it's outside zones then a fused connection is ok. Check BGB tho. Last edited by a moderator: Jul 13, A switched spur is NOT a socket, however I wouldn't put one too close to a bath or shower either, but they can be within 3m of a bath, Don't have my regs at my side but I think they can be anywhere outside zones 0, 1 and 2. AndyL - Arms. Reaction score Switched spurs FCU anywhere outside of the zones, so over mm from edge of bath not sure I totally agree with this bit, but that's what the book says Socket outlets 3m from the edge of the bath.

Still don't think i'll be adding sockets in bnathrooms, allowed or not. Cheers Andy, I better have a look at that one.
I know about the rooms with shower but didn't think it included actual bathrooms. Learn somet new everyday! AndyL said:. Not even if you move the tin bath away from the coal fire?
Put the spur outside the bathroom then wire from that to a flex outlet plate, no brainer, no arguments!!! Dave Its no problem digging a channel for the pipe but does it get cemented over or does it have to run in I live in the ground-floor flat in a Victorian terraced house.
