Justin Metzler on Instagram: "I wanted to build a bench across this shower, but wanted it to be open underneath - no intermediate supports. So this is how I reinforced it. Basically a small flitch beam. 1/4” x 3” steel plate bolted between two 2x4s. No noticeable deflection while standing on it, so I’m fairly confident the tile will be just fine. #shower #bathroom #bathroomdesign #showerdesign #diy #remodel"
