I’m just in the process of designing my extraction and supply ducts. Should extracts be as close as possible to a shower, or is there benefit of balancing its position beben the shower and the WC?

Which one do you mean? they do a few.

Can people really tell the difference in taste between tea made with 100 degree water and tea made with 98 degree water? The difference in price to get that extra 2 degrees is incredible. Remind me of cyclists paying extra hundreds of pounds to save grams on the weight of their bikes.

I would only seek planning permission for things that actually require planning permission. So the barn conversion for example needs permission, but do you actually need permission to put up fences? I think as long as they are under a certain height you can do so under your PD rights. Same goes for the access road. If you need permission for the road itself, get it, and ask for something simple and modest that will get approval. You can then build it and modify it or add the grander touches to it afterwards. The more you ask for, the more likely they will refuse. So keep your application streamlined and you will find it much easier. Often, permission is needed for installing a thing from scratch, but not needed to modify that thing to look like something else. So that is a loop hole worth exploiting.

This is what a friend warned me about. He said the Geberit ones are easier to install incorrectly for some reason and steered me towards Grohe. Not sure if that is everyone's experience though. Odd why they make it push fit, which is surely more likely to be installed incorrectly, compared to regular screw fit.

@Moira Niedzwiecka two and a bit years on, how is the Vitra toilet frame?

I should clarify, in case I haven't already, that the nervous break down thing is because my eyes are allergic to chrome. They much prefer brushed brass, brushed gold or matt black. Whilst some of these options are available in the Grohe and Geberit flush plate ranges, they are astronomically expensive!!! Upwards of £200 for just the flush plate. Now I may be may be mad enough to have an allergy to chrome, but I'm not mad enough to pay £250 for a geberit flush plate in "fine brass". I'm now considering Vitra, as they do some very nice flush plates for £20 in matt black. The frame comes with a 7 year guarantee, so hoping it is fine, but if anyone has any experience, good or bad, of Vitra toilet frames and cisterns, grateful if you could share. And if someone like @pocster wants to make fun of my chrome allergy, that would be fine too. If I don't laugh about this soon, I will have to cry.

Thanks @Vijay that's such a good idea. I had a look at their website to try and find the answers but was none the wiser, do assumed they won't that "customer facing" but clearly I was wrong. What frame/cistern did you go for in the end?

Alas, having started this post more than a month ago I still haven't managed to order a toilet frame and cistern or a flush plate. I seem to verge on having a nervous breakdown every time I try. In the Grohe range for example, how does one work out if the different parts are compatible with eachother? For example, are the following three bits compatible: This frame and cistern: https://www.victorianplumbing.co.uk/grohe-rapid-slx-1-13m-support-frame-for-wall-hung-wc-39600000 This flush plate: https://www.xtwostore.co.uk/grohe-arena-cosmopolitan-s-flush-plate-cool-sunrise-brushed-37624gn0.html This inspection chamber, which presumably I need as the flush plate is a small one https://www.xtwostore.co.uk/grohe-small-maintenance-shaft-for-cover-plates.html Will the inspection chamber increase the thickness of the installed unit, or can I still conceal all of this within a 18cm studd wall? I just find the diagram from Grohe incredibly unclear. I've pasted it below. It clearly says the max wall thickness is 230mm, but what's the minimum achievable with this unit? And the 10-70mm figure, is that an additional thickness to your wall of 10mm if you don't have an inspection chamber or 70mm if you don't? Thanks for your help in advance and sorry for being so dense about this!

Those who bought a Trojan, where did you get it from? I'm after the Trojancast Algarve 1700 x 750 and just received this from one of the few suppliers who purport to supply them: We are temporally unable to supply Trojancast baths due to extended lead-times from the manufacturer due to Covid.

The current idea is to go with a 300 litre unvented indirect hot water tank. Maybe that's too small? We won't be using this giant bath everyday. More like twice a week.

It's a gas boiler, Vaillant ecoTEC plus 48kw, or possibly the Vaillant ecoTEC 637 which is 37kW. Not sure at the moment.

Forgive me, I'm a complete novice at this. I will have a large unvented tank in the loft (i.e. one floor above the bathroom in question). And the mains from the street was 18 litres a min previously, but I'm hoping it will increase slightly when we widen the size of the connection. Otherwise people wouldn't bother widening these pipes, surely.

Well f=ma, so I agree mass is important. But presumably for that equation to balance, since the greater the pressure, the greater the force, acceleration becomes a function of pressure.

There is no internal pipe work at the mo. We ripped it out and are starting from scratch. Soo can spec whatever gets a good recommendation here. The (very) old connection to the mains supply gave us about 18 per minute max, sometimes less. We are widening the connection, but haven’t done that yet, so can’t test. I thought pressure was more relevant than flow as it’s an unvented hot water tank. Pressure is 2.8 to 3.1.

It’s huge. It has a capacity of 350 and standard baths are anywhere between 130 and 175. It weighs 140kg... empty!

It’s a Large Picasso bath from Lusso Stone. @Bitpipe has one I think. It is described on the website as: “Water Capacity to Overflow: 350 Litre” but I reckon I would take up at least 95 litres of that, so I need a filler that can do 250 litres. At 17.6 litres per minute it will take about 14 minutes. Not terrible I suppose, but if I could achieve something a tad quicker.

I’m considering a Vado bath filler. It’s flow performance graph is pictured below. Despite the tap’s official rating at 3 bar being 17.6 litres per min, the graph shows a much steeper second curve that would appear to reach almost 40 litres per min way before 3 bar. flow rate is important to me as the bath I’m filling is HUGE. Can someone explain what the “flow straightener” curve is please and how I can achieve the 40l/m rate? For background, I will have an UNvented cylinder and mains pressure is between 2.8 and 3.1 bar. Haven’t laid pipes yet, so could choose what diameter to optimise bath filler flow.

That would be great. Means I could pay my mortage off in the next 12 years rather than in the next 32.

That's exactly what they thought! If you look at the majority of tax havens in the world: Guernsey, Jersey, Isle of Man, Antigua, The Bahamas, the Cook Islands and Niue, Saint Vincent and the Grenadines, St Christopher and Nevis; The BVI... these are all protected territories of the UK. That is, they are independent but the benefit from our Supreme Court also being their Supreme Court (i.e. the Privy Council) and they also get military protection from the UK. The UK could threaten to withhold those two benefits (i.e. the rule of law and security) if these countries don't stop their tax havens allowing the Amazons of this world to fleece the UK tax payer. But they don't. This is not coincidence. Most UK prime ministers have a tonne of money hidden away in these tax havens and are in the pockets of big corporates.

I lumos do some nice products: https://hartingtonheath.com/product/i-lumos-8-x-16mm-warm-white-led-flexible-waterproof-neon-strip-light/

We are having a poured floor in our kitchen which will add 3.5mm to our screed. It’s too expensive to do in the utility room that is off the kitchen, so was going to tile there. The tiles I like are 8.5mm thick. So I will have a discrepancy of 5mm plus whatever thickness tile adhesive I need for an 8.5mm tile. This is going to be a trip hazard isn’t it? Suggestions? Haven’t poured our slab, let alone the screed yet, so still time to do something about it. Rather not change kitchen FFL though. Is it just a case of dropping the slab by 10mm or so under the utility room?

@wozza do you mean the Rapid SL? If so, what thickness wall did you put it into? I struggle understanding the dimensions on the attached spec sheet, is it saying the wall has to be 230mm thick or 165mm? GROHE_Specification_Sheet_38773000.pdf

Looks very technical! The nice thing about tado is it's idiot-proof.
