1 Bowl Granite Composite Kitchen Sinks

If you’re one that likes to break away from the norm then our collection of single bowl granite composite sinks might be just the right jam for your doughnut. They’re a brilliantly hygienic material which comes in a number of different colours so if you’re sick of stainless steel you’re in the right place. Kitchen sinks can have multiple bowls however a single bowl sink will tend to offer larger bowls and draining areas so choose wisely depending on your needs and how you wash up. Designs range from contemporary to ultra-modern so either way your kitchen is going to be looking extra stylish.

How do I choose the right sink size for my kitchen?

Look at the actual sink dimensions and how you use the space; this range includes lengths from around 300mm up to 1,100mm and common widths of 400–599mm, so there's plenty of choice. If you need a large bowl for pans and roasts, options such as the 1000 x 500mm models give a roomy single bowl and draining area. For a small galley or utility you might prefer a compact sink that still fits most tasks. Measure your cabinet and worktop space first, then match the sink length and width to what you need.

Are granite composite sinks hygienic and durable enough for daily use?

Yes. Granite composite sinks are hygienic and are offered in robust finishes that stand up to everyday kitchen use. Many models come with included wastes and practical extras, which helps keep the bowl clean and functional. You'll also find established brands such as Reginox, Rangemaster and Clearwater offering high‑quality options across the range.

Do I need a drainer, and how do I decide left or right handed models?

A drainer gives you a convenient drying area and room to rest pots, while drainerless sinks create a sleeker look and leave more counter space. Choose a left or right drainer to match your usual workflow and tap position so water drains away from the busiest side. For example, if you usually prep on the left, a right‑hand drainer keeps the working area clear.

How do bowl shape and depth affect practical use?

Rectangular bowls give a long, practical floor for baking trays and big pans, while square bowls suit compact or minimalist layouts. Most sinks in the range sit in the 200–299mm depth band, which is deep enough to soak large pots without splashing. Pick a deeper rectangular model if you wash roasting trays, pans and casseroles often, or a shallower compact square for quick tasks.

Which colours and finishes work best with different kitchen styles?

The range includes black, white, grey, cream, concrete, brown and even red finishes, so you can match many looks from contemporary to ultra‑modern. Black silvery or charcoal sinks add contrast against pale worktops for a modern kitchen, while pure white or cream gives a clean, integrated feel in a shaker or bright kitchen. Concrete and pebble tones are great if you want an industrial or natural aesthetic without stainless steel.
