Outdoor shower: Frame and sides
Each wing wall has a 6-foot-long corrugated metal roof panel that’s screwed to a frame made of 2-by-4 lumber.
Each frame requires two 90-inch side pieces and four 26½-inch crosspieces.
We used redwood for the frames, which was protected with a water-based sealer prior to attaching the panels. A less expensive option is pressure-treated lumber.
Panel options include clear, frosted, or colored fiberglass roofing, aluminum flashing, or colorful oil or acrylic cloth.
