Single taps, normally called pillar taps, are usually mounted one on each side of a washbasin, through purpose-made holes, or side-by-side on the bath. Each tap is secured by a backnut screwed onto the threaded portion, or tail, which fits through the hole. The threaded portion is normally ~4in BSP for basins and sinks, and Y4in BSP for bath taps. (Note Kitchen sink taps are usually much taller than basin taps. This allows room for a bowl to be placed in the sink, underneath the taps.)

Pillar taps |
There are several types of pillar tap:
• The rising-spindle type, where the whole spindle moves as the tap is opened.
• The more common, non-rising spindle type, where the spindle lifts the washer assembly.
• The Supatap, no longer made, but for which replacement washers are still available.
