The ‘Half’ toilet flush design by Jonathan Liow uses suggestive aesthetics to conserve water. Like many dual-flush conserving toilet tanks, the button presents two sides split in the middle that will either give a low or high-pressure flush.
However, you will notice that the low pressure side is white, smooth and inviting while the high pressure side is black, jagged and uncomfortable. The reason for this is to make people more conscious about their water usage. It appeals to the notion that you would more likely want to push something that entices you than something that is pushing you away. Therefore, Liow uses design to stir people away from unnecessary wasteful thinking. The Half toilet flush makes you think twice about sustainability.
