Keeping afloat with your water supply
A typical bath might hold about 100 litres of water – but we don’t usually fill the bath right to the top.
So we usually calculate that we use 80 litres of water when we run a bath.

That’s the same amount of water as in 80 of these one litre bottles! And all of that water then goes down the plughole.
