I'm wanting to move our shower from one wall (an outside wall) to
another (stud wall). All walls are titled, but will be re-tiled later.

I have a cold feed feeding the current shower from the loft. I was
planning to re-route the cold feed to the position of the new shower,
which would mean running the pipe in the stud wall along with the
mains supply.

How do I go about running the pipe through the stud wall and make the
necessary bends for lining up for the shower?
I'm not overly fond of plastic push fit connectors, but I'm open to
suggestions.

Thanks

Dave
