We recently saw ads for a new style of toilet. It has a cistern as usual, but the top of it is actually a basin and tap. So the water from washing your hands then goes into the cistern and is used to flush the toilet.

Instant use of your grey water with minimal plumbing and pipes – sounds like a great idea to us! Could save space in msall rooms, too.

We can’t give you a price or brand name, but it’s certainly something to think about next time you need a new toilet.
