===Butler's sink===
{{Anchor|butler|bs|butlers}}A ''butler's sink'' is a rectangular ceramic sink with a rounded rim which is set into a work surface.<ref name="Blower232">Blower, 2006, p. 232.</ref> There are generally two kinds of butler's sinks: the London sink and the Belfast sink.<ref name="Blower232" /> In 2006, both types of sinks usually were {{convert|62|cm|in}} across and {{convert|46|cm|in}} front-to-back, with a depth of {{convert|22.5|cm|in}}.<ref>Blower, 2006, p. 232-233.</ref> London sinks were originally shallower than Belfast sinks.<ref name="Blower232" /> (One plumbing guide in 1921 suggested that the Belfast sink was {{convert|38|cm|in}} deep.)<ref>Fletcher, 1921, p. 96.</ref> Some believe this was because London had less access to fresh water (and thus a greater need to conserve water), but this theory is now contested. It is more likely the two sinks had different roles within the household.{{citation needed|date=August 2019}} But that difference usually does not exist in the modern era, and both sinks are now shallow.<ref name="Blower232" /> The primary difference both in the past and today between a Belfast and London sink is that the Belfast sink is fitted with an overflow [[weir]] which prevented water from spilling over the sink's edge by draining it away and down into the wastewater [[plumbing]].<ref>Blower, 2006, p. 233.</ref>
