Domestic floor are designed for an imposed load of 1.5kN/m2
(30lb/ft2); you've got 1.05m of water = 10.3kN/m2 (218lb/ft2) - 7
times the load.

Does this mean when I stand with my feet together the floor is over
loaded
?

I weigh about 180 lbs and both my feet would fit within a square foot,
if
you'll pardon the pun (not intended)

No because you are a single point load. But if you put one of you in
every
square foot the floor would indeed be overloaded.

I've been to parties like that.

Yeah. Seem to recall BBC news showing a balcony collapsing at a party some
years ago which sort of proves the point.
