So last night John finished the glass-block shower wall. The 2 coolest features involved John cutting one of the blocks in half so we could have a rounded cap piece over our 4'' blocks (we could not find 4'' rounded blocks). He also put in some rebar and a bracket which I fashioned so that our shower rod would serve as a structural support and anchor the glass block.
Otherwise, I spent my time staining the new trim pieces, trying to match them up to the old. Here are a couple of shots showing the work.
