The standard number of plates for both electric and gas hobs is four. There are hobs though, which can have the number of plates ranging from one to six.
Hobs with enamel surfaces are available in a variety of colours. Ceramic hobs have a black surface but their frames are available in a wide selection of colours. Stainless steel surfaces do not offer variety in terms of colour although the stainless steel may be brushed which offers two alternative effects.
