Shower head holder / rail fell off wall. How to reattach

[ElCI]

Hi all. Had a shower today and the rail that holds the shower head fell off.
It seems odd, there is basically a small sharp spike sticking out the wall. Not sure if this is a disintegrated screw etc. Can't see much on the rail.

Looking to reattach obviously (or replace) but don't know how to do it.

As a short term fix, how are suction versions, are they generally secure?

There should be a flip off cap on the narrower end of the boss. If you can remove that there will probably be a screw head underneath it. You will need to remove the old rusty bits and refit with a new screw. Use stainless or brass screw. Also drill or file a slot to act as small drain hole in the bottom of the lower boss so that it doesn't fill with water and corrode the new screw. You will also need to remove the old screw thread from the wall.
Never used a suction version, not sure I would trust one.

Thanks just looked there and everything you've said seems to be correct.
Most difficult bit here seems to be the removal of what's left of the old screw.
I assume this will likely be a screw into a raw plug so I'll likely need to get both out and replaced? Any best way of going about this?

If you have a cordless drill ? Lock chuck on screw and then reverse it out , or use grips or pliers to slowly remove ( or you risk snapping it).You can reuse plug without removing ,If no screw protruding a HSS bit can be use to drill it out or drill new hole a few mm away .

Use a grinder and take the top off the old spike / screw. Drill a new hole slightly down (or up) from the previous hole. Be sure to be close enough that the fitting covers the old hole.
You'll need a tile drill (6mm likely). Take it slow and do not apply pressure otherwise you'll crack the tiles. Once through the tile and into the surface behind, you can then use a masonry bit (not on hammer) or wood bit depending upon what you're drilling into.
