I think this is brilliant. One bin for each person. When the bin gets full of shoes, we send it to their room and they put them away (this needed to happen when I was a kid because my brother and I would wear a different pair of shoes everyday and kick them off in the mud room instead of putting them away)
How-to corrugated steel shower surround. (How about using a "rainscreen" system to hold the panels out from the wall ~1/2" and waterproofing the wall behind?) Wouldn't it be cool to use bold color painted steel roofing panels for this application!
