I'm midway through refurbishing a one storey garage bedroom/annexe. The original plan was for the zone to be heated by radiators, including a wet towel rail in the shower en suite. This has now changed to wet UFH and an electric only towel rail. My problem is that all the wiring for the mains, shower, vent, lighting, toothbrush charger etc has already been chased and run through the cold flat-roof (now covered with PIR, tape, VCL and plasteboard).
The mains in this room comprises 6 double sockets on 2.5mm cable running direct from the fuse box. It is a daisy chain not a ring. Can I power the towel rail with a spur off one of the double sockets?
This would be convenient as one of the sockets is around 20cm horizontally from a not yet build stud wall partition on which the towel rail could be installed. I also have 10mm cable for the shower in the same stud wall.
thanks in advance for any help or advice
