In case you're wondering how we mopped the concrete subfloor, because admit it, that's the kind of stuff that keeps you up at night, it wasn't with a regular sponge mop. That would get torn up pretty quickly.
Instead, I used a string mop, along with one of these...
Look, it even matches the walls! It's like being inside a banana peel.
And yes, I am a neat freak, but no, I do not own a commercial grade mop bucket. It's actually on loan from my mom, who purchased it years ago when she redid all of her flooring.
