In its narrowest sense, it can be taken to refer to appliances such as wc bowls, cisterns, bidets, urinals, and washbasins (and sometimes sewerage pipes) that have traditionally been manufactured from porcelain (a ceramic material made from clay that might be described as ‘vitreous china’ when coated with enamel). This might be referred to as ceramic, porcelain or china sanitary ware, and is often white.
However, sanitary appliances are now made from a wide range of materials, including metals, acrylics, glass and so on and ‘sanitaryware’ is sometimes now interpreted to include a wider range of appliances that might be found in sanitary installations such as baths, showers, bins, incinerators, macerators and so on.
Sanitation, hot water safety and water efficiency, suggests that the term ‘sanitary appliance’ means a ‘… WC, urinal, bath, shower, washbasin, sink, bidet and drinking fountain. It also includes appliances that are not connected to a water supply (e.g. composting toilet) or drain (e.g. waterless urinal).’
