You use a wash basin multiple times a day, whether at home, work or in a café. Each time, like clockwork, you turn on the faucet, wash your hands or face and turn off the tap. What you often fail to notice is a small element at the bottom of the basin that helps drain out all the wastewater with ease.

This tiny feature is called a waste coupling - the most overlooked element yet one of the most vital parts of a healthy and clean bathroom. In other words, it is the unsung hero of your bathroom.
