Replace shower valve

[Elkato531]

Yes, those are the mounts.
I'd use copper but plastic should be fine if used correctly and inserts are used.

No wiggle room on the 150mm centres as those are the pipe centres on the bar valve. I have a piece of plywood with 2 holes drilled the correct distance apart which I use to hold the pipes in position during tiling.

Is that video showing the same fittings? Trying to visualize how they are installed. Very easily by the looks of that!

I’ve got concrete blocks under my plasterboard. Do I use the plywood as a jig behind the plasterboard to get the correct distance apart? Trying to understand this detail.

Sorry for the repeated messages on this. I noticed that some of these mixers - such as this - come with these fittings:

I am inclined to purchase this as I think Bristan is a reliable brand. Let me know if I am missing something. Thanks.

Only if it worth it price wise. The fixings shown earlier are easy to fit on any bar shower.

Are these not universal then? Would they not work with a different bar shower in the future?

The thing that thew me with the Screwfix fixings was that they appear to have a different thread (male/female arrangement) to what most bars ave.

No, only the same Bristan one.

They are universal and have fitted every bar mixer I've ever used.

Do these have a thread on the outside or inside? Can't tell from this pic:

The shower bars require a thread on the outside of the above fitting from what I can tell.

Outside.

Outside.

That's perfect then. Will use these and I can then fit any bar on top of this.
If I do buy the Bristan Frenzy pack, I will just discard their fittings and screw it straight n to this universal type.

You've answered the question now but this image, clearly shows the thread on te outside but the universal fitting wasn't clear in this regard.

Not sure how the frenzy works to be honest, never fitted one. Hard to tell from the instructions if it just screws on like a normal one.

do you recommend a particular type of bar and riser set?

UPDATE - here is how it went down.
The pipes are exactly 15cm apart. Any suggestions on how I get a tile on the section that has a void behind it?

Oh, I have nothing to do with this initial install!

 

[Elkato531]

Wrap the pipes in felt or foam insulation and fill the void with a sand cement mix. Hopefully the 15cm is pipe centres.
