Assuming the bathroom is upstairs you can do this quite easily by
siphoning it. If a hose is full of water with one end in the bath,
then providing the outlet at the other end is lower, all the water
in the bath will flow through the hose, even uphill, and out through
the bathroom window. Except for the final amount when you'll need
to hold up the end of the hose to allow the water to flow down
and through the window.

So first fit a stopper on the butt end. Then go back upstairs
and fill the hose from a tap on the bath just trickling will do
if you don't want a shower as well - until it's full, then put
your finger over it and put that end under the bathwater and keep
it there somehow. Then go back downstairs and put the other end
under the water in the butt and take the stopper off....

How easy is it to fill the hose with water if you've put a stopped in
the bottom end? - if you do it at a trickle, then the air can escape,
but try and run the water in too fast and don't you get problems?
