Of all the bathroom taps the bath tap has the greatest number of different types. The bath filler is the simplest, a hot and cold control feeding a single outlet that mixes the water before it enters the bath. The bath shower mixer has a diverter that allows the mixed water to be directed to a shower handset on the end of a hose. This is used for washing hair without needing a full shower. Bath pillar taps are seperate taps for hot and cold water. All types can also be mounted directly on the bath, on the wall or as freestanding taps on standpipes. The freestanding taps are popular with freestanding baths.
