Plumbing Question - Pipes serving shower

Norroy

I have taken over a property where the tiles on one side of a shower cubicle were coming away. We have now removed these tiles to reveal the hot and cold water pipes serving the mixer shower (exposed valve). There are no visible leaks.

What would be the best way of filling in the area around the pipes before re-tiling ? Sand and cement has been suggested. This is an outside wall.

Should the pipes be protected in some way before the gap around them is filled in, and do they need isolation valves ?

Ideally they should be boxed in.

I used a pipe cover and rendered them in. Im hoping there isnt a huge problem but its all easily isolated if there is.

I protected the pipework as pipes move a little and they can condense quite a bit of water which i cant imagine copes well with cement and pipework.

Great, thanks.

What sort of pipe cover did you use ?

I have seen those pipe insulation tubes, but I thought they were to stop external pipes from freezing.

Duct tape then fill with rapid set tile adhesive

Lime will eat the copper so you must cover with tape

I used radiator pipe covers.

The modern "professional" way is to use expanding foam, trim flush and tile over !
