This foot washing station may not be the most practical idea out there. Judging by the Facebook comments on this one, you’d think it was suggesting you cut off your legs and regrow them before walking into the house.
Anything with this many parts to the whole setup is bound to end up being a headache in the long run. Keeping track of those sandals and stocking clean towels probably won’t last too long. Even so, it’s a cool enough idea to help keep a house clean. Instead of going all out with the entire setup, a simple chair next to a hose with the rock setup to help filter out dirt will be a much more practical solution.
