As one of the most commonly used and looked at parts of your bathroom, they are a really important feature in terms of solidifying the style of the room. If you are wanting to refresh your existing sink, hot and cold basin pillar taps are for 2 holed sinks whereas a mixer tap is ideal for a one holed sink. Both have various designs that can offer either a traditional or contemporary feel. They can come in a range of colours such as a classic chrome or a modern black.
