What zone is under the bath?

To me, it seems to be no zone or possible zone 3. Therefore an electric skirting heat is permissible or pelmet electric heater, under the bath.

Behave,its the twilight zone.

To quote from BS 7671, said space is:

"Zone 1 if the space is accessible without the use of a tool."

and

"Spaces under the bath, accessible only with the use of a tool are outside the zones."

Don't forget the requirements for any accessible controls, though.

The space under the bath is in zone 1 if that space is accessible without using a tool. If you need to use a tool to get at the space under a bath then it is outside the zones.

Well the presence of a grill or similar heat outlet means that the heater would probably be classed as being in zone 1. This means that the appliance would have to be designed for such a location and that the supply must be fed through a 30ma RCD as per the regulations.

The control switch would have to be somewhere else though.

I TOLD you it was the furry monster zone...;-)

In other words, one could change the space from Zone 1 to outside the zones by,eg, putting a couple of screws through the pop-out panel?

Yes, provided you can't stick your fingers through any holes to reach anything electrical. A key is also acceptable.

Zone 0, if under the bath and access can only be gained with the use of a tool. Jaymack

Nope. Zone 0 is basically "underwater". It is outside zones.
