Hi
I'm looking to install a power shower in a bathroom refit. It is a Mira Vigour Thermostatic (low pressure water supply)
Question part 1:
Do I require earth bonding to be added to the shower?
The bathroom has not had an electric shower before. The bonding currently goes from one pipe of the radiator to the basin cold pipe (tee off for toilet), basin hot pipe, bath hot pipe and bath cold pipe. This is run in 10mm sq cable.
The bathroom has no electrics heaters or shaver sockets.
Does this need to be extended up to the hot and cold supply pipes to the shower?
The house is 20 years old, the consumer unit does not have an RCD and is the old fuse type.
I would appreciate some opinion after hearing that edition 17 of the regs has changed somewhat re bonding.
Question part 2:
Where is the best place to take the power for the shower?
The instructions do not advise, other than it pulls 150w max at 240v and that from source it will be wired in via an RCD at 30ma and a 2 pole FCU fused at 3A. Which I agree with. It does not have a low voltage transformer.
See page 9 here: http://www.taps4less.com/pdf/mira vigour guide.pdf
In comparison the shower I have in my own house (aqualisa aquastream) can be wired to a lighting circuit as well as a ring main via a RCD/FCU however it has a low voltage transformer.

The Mira shower will mount on a wall with the airing cupboard behind. There is immersion power available but I would rather leave that as a dedicated radial circuit.
So I can drop power down from the lighting in the loft?
Or the last option is to use the last spare fuseway in the CU and run its own circuit but this is least preferred because the bath and bath floor would need to be taken up, but can be if it’s a must.
Unfortunately the shower was an afterthought, after originally asking for a mixer tap with a hose!
Thanks for your time!
