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.
