Connecting Grohe shower using adapters to 15 mm supply

[Stants]

Either sealant method is fine, the "S unions" are the easy install adapters. Screw them into a straight coupling which solders straight to 15mm pipe.

Thanks for reply very much appreciated

Just have 15mm copper tube sticking out the walls for now then and get your self an easy fix kit.

I expect over 95% of plumbers ditch those connectors and use an easy fix kit, so much less to go wrong and can literally save an hour of labour working out wall depths etc

I bought the swirl fittings only thing I’m concerned about is on the ends the originals have a rubber washer / gasket whereas the swirl ones have nothing…… do I need something in there ? ( see pics )

Don’t worry.
When you attach the shower to the swirl fast fix you use either a rubber washer or a fibre washer, whatever is included with the shower, either is fine.
Ideally this washer has a mesh filter to catch any debris, you can buy them at any plumbers merchants if they are not included with your shower.

Just checked the shower back at home and there is a fibre washer and mesh filter ( see pic ) …… would it be belt and braces to add a rubber washer ?……and also PTFE on the thread

No fibre washer is fine on it’s own

As above just use the fibre washer.
Do it up nice and tight then turn the water back on. If there is a slight drip from either hot or cold just leave it for a while, the fibre washer will swell slightly and become watertight.
