How to Install a Belfast Sink Unit

If you're thinking about making changes to your kitchen or just want to update the main part of it, putting in a Belfast sink can really improve how it looks and works.

The Belfast sink is well-liked because of its pretty ceramic look. It mixes old-fashioned beauty with usefulness, making it a great pick for any kitchen wanting to look good and be practical.

This guide will help you easily put in a Belfast sink by yourself.

Getting to Know the Belfast Sink

Let's start by looking at what makes a Belfast sink special. It has a big, deep bowl that gives you plenty of space for washing big items like pots and pans.

It's useful and also has a classic look that brings a cosy, country feel to your kitchen.

The Belfast sink works well in all kinds of kitchens, from modern to traditional, so it's a good choice for anyone looking to update their kitchen.

Key Features:

  • Deep basin: Provides ample space for washing large kitchenware.
  • Ceramic construction: Offers a durable and easy-to-clean surface.
  • Stylish design: Enhances the kitchen's aesthetic with its traditional charm.

Preparing for Installation

Choosing the Right Cabinet

A Belfast sink typically requires a 600mm wide cabinet for a snug fit, check out our Belfast Sink Base Units.

The cabinet should be approximately 450 to 500mm high, featuring a single door that can be mounted to open from either the left or right.

This versatility allows you to customise the installation to suit your kitchen's layout and your personal preferences.

Selecting the Worktop

The choice of worktop is crucial for the installation of a Belfast sink. Opt for solid materials like timber, quartz, or solid surface composites.

These options not only complement the aesthetic of the Belfast sink but also provide the durability needed to support the sink's weight and usage.

Laminated worktops are not recommended, as cutting into them for sink installation can lead to damage and require premature replacement.

Step-by-Step Installation Guide

Step 1: Position the Cabinet

Start by placing the cabinet in the desired location for the Belfast sink. Ensure it is level and securely positioned, as it will be supporting the weight of the ceramic sink.

Step 2: Install End Panels

Attach an end panel to each side of the base unit. These panels are essential for covering the sink's edges, offering a polished and neat finish to the installation.

Step 3: Prepare Waste Holes

On top of the cabinet, outline the waste hole with a pencil before cutting. This hole should be large enough to fit the sink's waste, allowing for efficient plumbing and waste disposal.

Step 4: Install Taps

It's easier to install the taps into the worktop before placing the Belfast sink. This pre-emptive step simplifies the process, preventing any awkward manoeuvres once the sink is in place.

Step 5: Fit the Sink

With the cabinet, worktop, and taps ready, carefully position the Belfast sink onto the cabinet. Ensure it aligns properly and sits securely on the cabinet, ready for the final connections.

Finishing Touches

Once the Belfast sink is installed, you can focus on the finishing touches that will complete your kitchen's transformation. Consider the following to enhance the functionality and aesthetics of your new sink:

  • Sealing the Edges: Apply a waterproof sealant around the edges of the sink where it meets the worktop to prevent water damage and leakage.
  • Backsplash Installation: A backsplash not only protects the wall from splashes but also adds a decorative element that can complement the sink and worktop.
  • Accessories: Sink grids, strainers, and cutting boards designed for Belfast sinks can enhance usability and protect the ceramic surface.

Maintenance Tips

To ensure your Belfast sink remains a stunning and functional feature of your kitchen, follow these maintenance tips:

  • Regular Cleaning: Use a mild detergent and a soft cloth to clean the sink daily, avoiding abrasive materials that can damage the ceramic.
  • Stain Prevention: Wipe up spills and stains promptly, especially from acidic substances like lemon juice or vinegar, which can etch the surface.
  • Chip Repair: In the event of chips or scratches, use a ceramic repair kit designed for sanitary ware to maintain the sink's appearance.


By choosing to install a Belfast sink, you're not just adding a practical item to your kitchen; you're also bringing in a piece that has a timeless appeal.

This sink type is perfect for anyone who wants to combine good looks with functionality.
