Belfast Sinks & Butler Sinks

Belfast and Butler sinks may look similar, but their dimensions, features and fitting requirements can vary considerably. These FAQs explain the traditional distinction and the practical details to check before ordering.

 

What is the difference between a Belfast and a Butler sink?

Belfast and Butler sinks both look very similar but differ in terms of size and drainage placement. Belfast sinks, smaller and deeper, fit a 600mm unit and have the drain closer to the tap. In contrast, Butler sinks are wider, fitting an 800mm unit, with a slightly more shallow bowl and the drain situated in the middle. Traditionally, Belfast sinks had a deep bowl and a weir overflow, while London Butler sinks were generally shallower and did not include an overflow.

 

Should I choose a single or double bowl Belfast sink?

A single bowl Belfast sink provides one uninterrupted washing area, which can make it easier to accommodate trays and larger pans. A double Belfast sink is usually wider, and gives you separate spaces for tasks such as washing, rinsing and food preparation.

 

Do Belfast and Butler sinks have an overflow?

Some do, but not all. Although an overflow is traditionally associated with Belfast sinks, modern Belfast and Butler designs vary. Check whether your chosen sink has an overflow and which waste it requires. The waste, overflow kit and plumbing fittings may not all come with the sink, so confirm what is included before ordering.

 

Do Belfast and Butler sinks need additional support?

Yes. The cabinet must support the sink securely from beneath rather than leaving its weight to the surrounding worktop. Ceramic models can be particularly heavy, especially when filled with water. Due to this, the sink may require a reinforced cabinet, supporting shelf or frame.

 

Should a Belfast sink sit above or below the worktop?

It very much depends on the sink and its approved fitting method. The rim may sit slightly below, level with or above the adjoining worktop while the apron remains visible at the front.
