Replacing a 65mm centres shower

[Akustik]

I have a Aqualisa Aquastream power shower that I want to replace with a mixer shower as I'm about to go with an unvented system.

The only problem is, the pipes feeding into the power shower are 65 mm distance apart.

Has anyone had any experience with a similar situation?
Do they sell mixer showers with that distance? The only ones I was able to find had 50 mm distance - close, but still the wrong size.

Is it a big mess to change the pipe distance? How much demolition would it require as they're behind tiles inside drywall.

Nope, thats an old setup where some shower outlets had bespoke inlets.

You still do get 'designer' bar mixers that have the supplies at a non standard distance but in the main most support the 150mm standard.
