BFO drill bit, wiggle:

Just draw rectangles to represent the various tray options and overlay on your CAD drawing which will have the UFH pipes shown exactly. ?

If that wall is "cold" couldn't you just redo in insulated pb? You'd need some back box extenders for the electrics. Probably not what you want to hear as a suggestion...

If it's not leaking...don't worry but keep an eye? That's as you say more of a twist rather than a kink. Weird how that happened.

So in your wall buildup you don't have actual vcl? Your relying on the parge coat for air tightness?

@phatboy, was there any sign of mould before the MVHR?

Pissing people off's OK though is it? There's ways of getting your point across. Stating your disinterest in other people's opinions or feelings isn't going to win you any friends on here or have them want to engage with you. As an aside i personally think a badly maintained MVHR system could be a very serious health hazard. On the for side there are people on here who's chronic health conditions have much improved I believe due to well designed MVHR.

4 years, if only! According to Flickr I "broke ground" Dec 2010: Bricking up Jan 2011: Dates on the photos must be wrong! ?

And the rest!

Matches the holes in the bricks to tie everything together.

Buy? Wuss, @Onoff MADE his own former then came up with his own concrete recipe! The glass gets CT1'd down I believe along the bottom edge and that's it. I think a tray will always direct water better and quicker to the drain as it's smooth whereas you've grout lines with a tiled former. At least that's my experience. Really pleased tbh the way my wet room corner came out especially the "union jack" cuts in the cheap ceramic floor tiles. With hindsight I'd have gone for 2% slope rather than the 1 / 1.5% I achieved. Keep having to clear the hair trap in the wall drain here the way the women in this house moult.

4 holes out of 42 drilled for my plate lintels! Quite impressed with the hole saws so far in 5mm 304 stainless plate. No blunting or loss of teeth! Used with cutting fluid in the small pillar drill. They're stamped Hss rather than Hss Co. Cut as clean as a whistle:

Standby Power Consumption QUR323 dual: <0.3W

This "cable coming down from the ceiling" where does it come from, the lighting circuit, ring main etc? Nothing to stop you I guess feeding that 4 gang block with it but fuse it appropriately depending on where it comes from.

QUR323 is 85-260V AC input. Doubt very much if it'll work on 12V AC. I'd say in fact it won't.

Impressed by the response. Elderly neighbours were robbed by distraction thieves, one came up the front and kept them talking, the other went around the back. CSI took 2 days to come. Mind these rural coppers are busy...

Big? I think at the time you could book a tour:

ENER-J stuff might be worth looking at. I think its Quinetic stuff under another name. Zigbee and Thinkbee are similar. As I said in another thread my Quinetic switch paired with my mates Thinkbee receiver. IKEA even do their TRADFRI range: https://www.ikea.com/gb/en/search/products/?q=tradfri I dont know if it uses the same protocols as Quinetic, or is Alexa compatible etc but the socket is only a tenner.

My spindle was a bigger diameter than the splined section so not an issue... ...as is @vfrdave's:

Just to be clear, mine is a standard arbour but has the pilot drill removed. The spindle becomes the pilot in effect. From memory I put a drop of lube on the spindle. Wanting to say it was light machine oil but probably whatever was to hand so like likely silicone grease...

It's centering it over the spindle that's the issue now that the fittings are in behind the tiles. I can post my drilled one Monday morning if he wants. Mine is drilled 9mm diameter btw about 85mm in from the end of the grit edge. If you can be more accurate on the spindle size I can drill it bigger before I post.

Just saying that I and pocster plus many others I'm sure, didn't realise you could swap parts like that. Good to know. And where to go to get individual parts at good prices? Wouldn't Mr Average pay more for a "custom" build?

Yes it does. Without faffing, to the average buyer not in the know. https://www.geberit.co.uk/products/bathroom/geberit-flush-plates/

I'll have you know his driving instructor said if ever he needs a lift home from the pub he'd happily be driven by my lad.
