The traditional difference
| Belfast sink | Butler sink | |
|---|---|---|
| Overflow | Has a built-in overflow weir | Traditionally no overflow |
| Depth | Usually deeper | Traditionally shallower |
| The story | Belfast had a plentiful water supply, so its sinks were built deep with an overflow | Associated with the butler's pantry, where shallower sinks were used for washing glass and silver |
Today many manufacturers use the names loosely, so check the specification: depth, and whether there is an overflow.
What to check before you buy
- Weight: fireclay sinks are very heavy. The base unit must be built to carry the sink when full of water.
- Base unit: most need a dedicated sink base unit, usually 600 mm wide or more.
- Taps: these sinks have no tap holes, so taps are mounted on the worktop or wall. Bridge taps and pillar taps suit the style.
- Waste: check the waste size, and whether a basket strainer is included.
- Crockery: ceramic is unforgiving, so a sink grid or mat protects glasses and china.

Frequently asked questions
What is the main difference between a Belfast and a butler sink?
Traditionally, a Belfast sink has a built-in weir overflow and a deeper bowl, while a butler sink has no overflow and is shallower. Many modern butler sinks now include a small overflow, so check the specification.
Why were butler sinks made shallower?
They are traditionally associated with London, where water was scarcer and shallower sinks used less of it. Belfast had a plentiful supply, so its sinks were made deeper.
Do Belfast sinks need special taps?
They have no tap holes, so taps are mounted on the worktop or the wall. Bridge and pillar taps suit the style.
