Why Choose a Belfast Base Unit?

Belfast and Butler sinks need a purpose-built home. Unlike standard base cabinets, a Belfast base unit is designed specifically to house and support the deep ceramic farmhouse sinks found in traditional kitchens, country cottages, and modern Shaker designs. Because these sinks are heavy and sit at a specific height, a dedicated unit isn't optional, it's essential for a proper, level fit.

This unit is manufactured in our Manchester workshop and dispatched using the rigid Quickcab system, giving you the strength and stability of a fully built cabinet with the speed of a 2-minute assembly. No tools, no glue, no flat-pack frustration, just slide the panels into place, snap the connectors, and the cabinet is ready to fit.

Belfast Base Unit Sizes

600mm Single, 455mm Height – Suits standard Belfast sink models. Pairs with a single 450mm × 596mm door.

600mm Single, 495mm Height – Suits taller Butler sink models. Pairs with a single 490mm × 596mm door.

800mm Double Base – A wider option for installations needing extra cupboard space alongside the sink, using two 495mm × 396mm doors instead of one wide door.

Doors are sold separately across all sizes, so you can match the colour and finish to the rest of your kitchen.

Construction & Quality

Every Belfast base unit ships with gable ends, a solid 18mm back panel, and colour-matched cover caps for a clean, finished look. The 18mm back panel is specifically engineered to support the weight of a heavy ceramic Belfast sink, built around the load-bearing requirements of a typical Belfast or Butler installation rather than a standard base cabinet.

As part of our rigid Quickcab range, the unit arrives semi-assembled, with most of the structure already built at the factory. You simply slot the remaining panels and connectors into place, a process that typically takes around 2 minutes with no specialist tools or equipment required.

Sizing & Compatibility

Available in 4 in-stock colours, White, Light Grey, Dust Grey, and Oak, at a standard 560mm depth across all sizes. Both heights are built to UK kitchen industry standards and fit all major Belfast and Butler sink brands, including Caple, Lamona, Reginox, Villeroy & Boch, and Howdens.
