The location of the puddle on the floor can give you a tremendous hint when trouble shooting.
With respect to the car's position on the garage when parked, what was right over the puddle? The radiator, the water pump housing? The coolant reservoir tank?
If the car was moved, let it again sit until a puddle developes and locate the component right above it.
The leak will not be on top, because if the car was not driven, the water would have settled on the bottom.
