I have a shower that I totally gutted out. I plan to implement a regular shower head and another rain shower head. I already have the majority of the work done and have only one thing left: to run a piece of pipe to the attic, then stick it out back to the shower (around 3-4 feet through the attic).
I have a couple ideas, but not sure which to pursue:
- To build a box in the attic (ceiling drywall, plus add a piece of plywood on top of the joists in the attic to create an air tight space for the pipe) and cover with insulation
- add some heating element round the pipe
- just leave it as is but make sure that the pipe is sloped. This will allow the water to get out of the pipe when there is no pressure (my distribution valve will leak it through the on-the-wall shower).
What is the best way of doing this?
