Hi Folks,
I intend to fit an electric towel rail into a dressing room that contains an alcove shower (three solid walls and one sliding glass door into the dressing room).
My first query is regarding the bathroom zones of a tightly contained shower in an alcove... do the usual zones apply? I cannot find any resources online that specifically talk about alcove showers.
Assuming that bathroom zones are applicable in this area, this work will then be covered by part p, and I will notify building control and carry out the first fix ready for their inspection and subsequent testing after fixing.
The ideal position for the rail will be in zone 2, within 0.6m of the entrance to the alcove. I will look for a heating element of IPX4 or better for this site. My problem is what to do with the loose end of the flex from the heating element... There is no where in the room that is more than 3m from zone 1, so as I understand it I cannot use a standard flex outlet plate.
I wonder if I can pass the flex from the heater element as a single run through the hole in a flex plate (bypassing the connections) and then directly into plastic trunking (to be recessed in the wall) to be connected to a suitable junction box under the floor? That could prove to be a problem if the heating element needs replacing (I am assuming the connections of the flex to the element are moulded, necesitating replacement of cable and element at the same time???).
Alternatively is the underside of a shower with upstands considered a safe place to site a terminal box and make such connections (this seams to be the same as under the bath, as this would require tools to access... but perhaps more prone to water ingress!). Are there any types of junction boxes that can be used in zone 2, or is it acceptable to construct a watertight box to house a standard flex plate that could only be opened with tools?
I intend to bring power to the final junction box by spurring the mains ring via a heavy duty junction box, passing the spur through a fused rcd unit, followed by a timer unit (in that order) both to be sited in a cupboard outside the dressing room. Having recently spotted an RCD on the consumer unit, I now believe the RCD on the spur to be unnecessary????
Thanks in advance for any advice, suggestions or observations....
Regards,
Peter.
