Then we add the fittings to attach the tubing too. Notice we've also added a fitting at the top (bottom left corner) for water to be sent to the shower head.
Time to put some heat to it!

First you heat the joints up with a blow torch.

You get it to just the right temperature

And then bring in the solder. Can you see the silver solder at the joints?

The solder is pulled into the joints

And seals them up.
Once the shower mixing valve is soldered and cools off, it's time to install it in the shower.

We place a 2x4 behind the hole cut in the center of the shower for mounting the mixing valve to.

The mixing valve is placed in the opening, against the 2x4 on the back side.

This way we can make sure the mixing valve is placed exactly center in the opening. Then it's just screwed to the 2x4 through the front.
We also have to mount the shower valve up top.

The opening for the shower is much smaller, so we attach it first to another 2x4 block

And attach that to the studs in the wall behind the shower.

Then we can screw the shower head arm on

And the showers are done! We will still need to add the decorative plates and the shower head, but that comes after we finish up drywall and flooring. Cannot wait for that!
So have you installed a shower before? Have you done a tiled in shower? Would love to hear about your experiences as well!
