Half-inch rigid PVC pipe was part of my plumbing-supply purchases.
The featured Amazon option is Seven-Inch Clear Half-Inch PVC Section.
Nominal Pipe Size versus Tubing Bore
I used SketchUp to plan the interior and put body openings ahead of the framing, floor and wall panels.
My Interior Preparation notes included the shower drain and openings for three water tanks in that preparation sequence.
I removed cargo tie-down hardware for later framing mounts and door trim for the later insulation and paneling.
The cargo floor during my preparation session before sound deadening.Removing stuck-on residue during the floor cleanup.
My Takeaway for the Build
The tank and shower openings were included in my early interior plan. For the half-inch pipe purchase, the comparison keeps the size description clear. The clear and white sections use nominal PVC pipe sizing, while the Eastman option is flexible tubing measured by inside diameter, changing both dimensions and routing format.

Current Option
Clear Schedule 40 PVC
Nominal Size
1/2 inch
Length
7 inches
The current clear Schedule 40 option is a seven-inch section of nominal half-inch PVC. Nominal pipe size and physical outside diameter are different measurements. For a small pipe-layout project, compare the actual pipe and fitting system, then mark the finished cut length with the socket engagement included. Keep this short current option distinct from the original pipe purchase.
Does Nominal Half-Inch Mean A Half-Inch Outside Diameter?
No. Nominal pipe sizing identifies a pipe system. Use the actual dimensional reference and matching fittings when checking the physical fit.

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.
