As the world of plumbing has evolved and changed over time, the age of separate taps for hot water and cold water has come and gone. Basin mixers are - essentially - two taps in one. One spout allows for water of all temperatures to flow out into your basin.
The use of a single spout for both hot and cold water allows for easier temperature control than when using two - making it much safer for the vulnerable, such as children and the elderly. Such a feature also allows for a far more elegant appearance - looking stylish and modern with a smoother, more streamlined flow. A mixer also frees up more space on the limited surface of a basin and makes cleaning and maintaining it easier.
When it comes to purchasing, these faucets are the more economic choice, as the quality of the product far outshines anything that has come before it - with the amount of water less than that coming from two individual taps. They vary widely in size and shape - making it easier to find one that best suits your basin and, essentially, your home. Given the wide range to choose from, it may be difficult to select a basin mixer tap on your own.
