Nero - NLT posted some good advice about tiling and plumbing on my thread. Plumbing depends a lot on whether you have metal (copper or iron) or plastic plumbing connecting to metal taps. Metal plumbing is specialized, and I would not personally attempt to do more than connect by screw fittings - and plumbers hemp, (if you can get it) is better than plastic tape for metal fittings btw, as it expands slightly on contact with water UNLESS it is drinking water. {lastic is OK though - you know, that thin stuff.
But pushing a piece of metal piping back into the wall and securing it appropriately isn't difficult, and may be all that is required.
The r that your SO has with OW isn't what you think it is. It took me a long time to get beyond that thought.
