Most of you probably remember this fabulous Before & After: $1,000 Bathroom Makeover that we featured this summer. I, on the other hand (with my failing memory), forgot about it until I saw it again on Remodelista. What I was particularly drawn to on a second viewing of this bathroom was the corrugated tub surround and its $21 price tag.
In theory, corrugated metal sounds like a rust disaster waiting to happen, it's actually quite durable and corrosion resistant. Janet over at Remodelista explains that most corrugated metal comes with corrosion-resistant coatings (such as zinc). Also, "aluminum siding is great for indoor applications as it is softer to work with, and because the aluminum reacts with moist air to form aluminum oxide. This reaction creates a very hard coating that then seals the aluminum surface from future deterioration."
For the remodel from Country Living, the galvanized sheets were cut to fit (ask a carpenter for help) and then finished with Rust-Oleum Crystal Clear Enamel before screwing them in place. Self-sealing roofing screws and metallic caulk were used to prevent leaks.
