Replacing wall tiles after changing shower.

So I changed out my shower and I'm left with a bit of a hole in the wall.



I'm installing the new shower mixer today and then I need to replace the tiles

when I replace the tiles how should I do it?

I assume that doing it all at once won't work and I should smooth out the wall and let it set for a bit before trying to stick the tiles.

How long should I let it set? Do I need to scratch? What ratios for the mortar would be best for this?

How are you going to fasten the new faucet ?
Are you planning to just "cement" it in ?

Is that some kind of poured wall.

Precious faucet was secured with a piece of bailing wire.

I guess I could chisel a little deeper and loop a new piece of wire around what ever it was tied to. but I had sort of figured that securing it to the pipes would keep it in place until it was "cemented in". I'm not changing the shower head part of the pipe so that is secured at the top.

Here's the top of the shower which is staying

It's appears to be a brick wall covered in plaster.

Ok, got the soldering done and there appear to be no leaks.

I was thinking about what you said about holding it in place so was thinking about putting tapcon ing a small clamp over the shower valves to hold it inplace

The other tiles are stuck with a much darker grey mortar than whatever the wall coating is. So it definitely seems like I need to do it in two steps.


What should I pack the pipes in with?

The guy at the hardware store said 1:4:12 (cement, cal, sand) while a handy friend said to half the cement so 1:8:24

I ended up securing it with some bailing wire to a piece of rebar behind it. Everything checks out with the level and nothing leaks, now I just need to go about packing it in and sticking the tiles. Any suggestions on the type of mortar to use and how long to let it set before sticking the tiles?

Here's how it looks now:

Copper never should have been in direct contact with the cement, it will corrode.
Made it a whole lot harder on yourself by using a two handle faucet.

The copper was and will be taped.

It was in near new condition when I took it out and it had been in that wall for almost 30 years.

If cement is a problem should I just use a cement free mortar to fill it in? If no cement, what proportion of lime to sand?

And yes I know the two handle faucet made everything more difficult but trust me the set (which matches everything else) is really quite beautiful.

Ok I went with 1:8:24 (Cement-Lime-Sand) mix and packed it in. How long should I let it set before trying to stick the tiles on?

The problem was the decorative guard, I couldn't find replacements and it was impossible to drill even with a carbide bit. I ended up having to cut out a little notch with a diamond disk which was fortunately covers by the fixture. Even that took time, not sure what material it was, but it was far harder than any tile I've cut.
