Yeah, minimalism is great to reduce dirt/dust collection points.

By the way, I think toilets which are attached to the wall instead of to the floor are great because you can easily mop under them.

I like the stealth treatment you apply to the loo to reduce edges. Without wishing to imply my own bathroom needs a clean this would actually be handy in people's homes too (even though generally people are less wayward than they are in public loos)
