Half-inch rigid PVC pipe was part of my plumbing-supply purchases.
The featured Amazon option is Seven-Inch Clear Half-Inch PVC Section.
Where it fits my build
My Day 87 plan put the body openings ahead of the aluminum framing, flooring and wall panels. I specifically included the shower drain and the openings for three water tanks in that order of work.
I removed cargo tie-down hardware to leave mounting points for the extrusion framing, and removed door trim for the later insulation and paneling. SketchUp helped me plan how those separate jobs would fit together.

My build notes
The useful part of this diary entry is the sequence. I wanted to finish the drilling while the interior metal was bare, so later work would not mean opening finished surfaces again.
The photographs show my preceding floor-preparation session. Sweeping, washing and removing residue created the starting point for the interior work I described next.
I planned the openings and mounting access before enclosing the interior.
Alternative products
Two alternatives to compare
The clear seven-inch section and longer white pipe use nominal half-inch pipe sizing. Eastman offers flexible tubing measured by its inside diameter, giving a different routing format from the rigid pieces.
VENTRAL Half-Inch White PVC Pipe
This white Schedule 40 PVC pipe uses a nominal half-inch size. The linked cut length is forty-eight inches long.
