Bathroom Electrical - Nz Law Requirement?

Hi all,

Just trying to plan my bathroom, I am about to start renovating, so I can plan the layout correctly can someone please help confirm my questions.

Questions.

I understand I can have a heated towel rail directly beside the bath as long as the towel rail is ip rated + the connection is also waterproof.

If the sparky uses a permanent connection unit for the wire off the towel rail, can this be right beside the bath (200mm away) which will be 1 meter away from the wall spout (bath tap) or does the PCU need to be outside zone 2 (600mm away) from the bath.

Secondly if it can be installed that close, because it is using a PCU does the circuit need a RCD?

Thirdly does it need to be on it's own circuit.

Forth - Standard ceiling 2.4M, I can just use normal LED lights, without IP rating.

Fifth - I have a Weiss heater, if I put it above 2.25M on a PCU, does this require an RCD on the circuit?

Again can I put this 200mm away from the bath (above 2.25M high?)

Appreciate answers.

(note I have read section 6 multiple times, but although I believe I am right, I want to check my interpretation is correct. Yes I will get a sparky but I don't want him to come out until I need him as I live rural.)

Anything above 2.25 is un-zoned so essentially do as you please. Heaters and fixed appliances (like your towel rail) dont require an RCD. Towel rails are normally run off the closet lighting circuit as they draw only between 60 - 100 watts, can also be run from local power point if easier.
Instead of using a PCU for the towel rail use the hidden plug in cable in the leg (most, if not all towel rails allow for this these days). Then you can put in Zone 1 (if towel rail is rated to do so / most are)
