since the dimension of the room is 6 x 6 it has only a floor of 6units lenth and 6 units width,
if it has side walls a third numeral should be there with 6 x 6 (for example 6 x 6 x 8)
so there no side walls
you can walk out away from the floor in any direction you want
be carefull not to fall in the drain ,it might be dirty
