We did our bathrooms, and learning the plumbing aspect was probably the most interesting still addition for me. My father in-law taught me how to do copper pipe soldering, and stupervised the upstairs plumbing.

Feeling emboldened, I ordered a shower kit off of Amazon. Ye gods... the 4 head unit came with a tin template and a 'good luck'. Ended up putting together a 4 head double loop with pressure equalization.... after many, many attempts.

After those projects, I'm reasonably OK with it. Will be using coper piping when the zen 3 threadrippers finally hit the store.
