OK- so he didn't use a 'real' floor box! Let's at least give the guy credit for having his heart in the right place; there is a gasket, the cover will keep stuff from dripping in, and -if all are placed like this one- they are out of the way of foot trafic.
Not that I expect the covers to last very long!
Even a rated floor box would allow stuff to drip inside, and surely wouldn't keep mopwater out whereever there was a plug inserted. I think this application would be better served by "tombstone" pedestals for stuff under the counters, and drop cords for everything else.
As nice, reliable, and prooven GFCI's are, they are no substitute for good design.
