Hi everyone, We’re going to have our bathroom refitted in the very near future and we’ve decided we’d like a spa bath and a digital shower (not pumped but digitally controlled) Bath: https://www.thewhirlpoolbathshop.com/single-ended-baths/aquaestil-plane-solo-14-jet-whirlpool-bath shower: https://www.plumbworld.co.uk/mira-platinum-digital-shower-dual-concealed-101375-27988 I’ll have an electrician out to install the power but I wondered if anyone had any experience with this type of electrical install? The sort of cost to expect would be great too, we’re in south east London so a rough figure would be good as I’d rather not be overcharged! I’m assuming that the electric will be taken from the plug socket in the bedroom next door, drilled through into the bathroom and then run through an RCD and isolator? Is it possible to have an isolator in the bathroom on a pull cord above the door? (Please remember I’ve no experience of this and am not doing it myself, the bathroom is going to need to be replastered too and I want to make sure I have some knowledge for when an electrician visits for hiding of cables etc). Can the digital shower unit be installed under the bath? The Mira documentation says it can but it doesn’t seem right to me? Will there need to be more than one isolator with the electrics with different power going to two different pieces of electronics? It’s only a small bathroom and we’re going to have a small stud wall fitted to conceal the pipes for the wall mounted shower. Thanks in advance, any insight you can give me would be very much appreciated. Robbie.

The manufacturers of our digester has specified an IP66 rated RCD protected socket for the supply for the poo tank bubbler. The dedicated circuit planned for that supply (SWA 2.5, T+E, buried - 10 meters or so) is already RCBO protected. Do I also need RCD protection on the twin socket , or can I simply fit an IP66 socket in the knowledge that the circuit is already protected by the RCBO? I'd like to bury the SWA cable in the same trench that I dig for the poo tank pipe. Bet that's verboten innit?? Thanks in advance @ProDave or @JSHarris or @Onoff or anyone clever enough to know the answer ☺️

One rather nasty thing that was fitted to our old house when we bought it, was a single socket inside a cupboard in the bathroom, about 3m from Zone One. The previous owners had a small (500mm wide) tumbler dryer in there, apparently, as there was a vent pipe that ran up and directly into the loft space (!) when we bought the place. Given the house doesn't have an RCD, I replaced the socket years ago with one with the built in RCD, and whilst aware that it was borderline with the regs, it's been handy to have access to power in there. Now it's time to sell, I've been debating taking it out. The problem is that the cable was put in when the house was built, so is on the main ring final and chased into the wall. To do a proper removal job means taking the cables out of the wall, reconnecting the ring final in the loft above and then making good. Strictly speaking, this socket is probably legal, as there's no way that water can get sprayed on it (it's at the back of a 600mm deep floor to ceiling cupboard), it's protected by an RCD and it's more than 3m from the bath/shower. However, I personally don't like it, and although our surveyor never picked it up when we bought the house (despite the tumble dryer being fitted at the time of his survey) I'm acutely aware that things are a lot tighter now when it comes to surveys. I've contemplated fitting an (admittedly ugly) IP66 socket box in there, fitted with the existing RCD single socket. Technically I think that should be legal, notwithstanding the fact that I still don't like it, but if anything the IP66 housing would make it more noticeable. I'm tempted to just leave it as it is and put some stuff on the shelf that's now just below it so that it can't be seen when the surveyor comes around, and let the purchaser deal with it if they feel they need to. Anyone any thoughts?
