Sinks in our range

  • Stainless steel undermount, one bowl: a single bowl fixed beneath the worktop, in square-edged designs that suit a modern kitchen.
  • Stainless steel undermount, two bowls: two bowls side by side, so you can wash up in one and rinse or drain in the other.
  • Black granite composite: a single bowl made from granite particles bound in resin, with the look of natural stone.

What to look for in a kitchen sink

  • Undermount fitting: the sink is fixed beneath the worktop, so there is no rim on top. You can wipe crumbs and water straight into the bowl.
  • Stainless steel: a durable grade of steel that takes hot pans and years of use. Brushed finishes hide fine scratches best.
  • Granite composite: granite particles bound in resin give a hard, matt surface that resists scratches, heat and stains, in black to contrast with a pale worktop.
  • Bowl layout: a single bowl from compact to generous, or two bowls side by side, so you can match the sink to your base cabinet and the way you wash up.

How to choose

Bowl size

One large bowl takes oven trays and big pans flat, while a compact single bowl suits a narrow cabinet or a second prep sink. Check the bowl’s depth as well as its width; the capacity is on each product page.

Your tap

If you’re choosing the tap separately, you could fit one of our boiling water taps. Check the tap’s reach suits the bowl.

One bowl or two?

A single large bowl is best if you wash big pans and trays by hand. Two bowls suit a household that likes to keep washing up and food prep apart, or to leave something soaking while the other bowl stays free. Two-bowl sinks need a wider base cabinet, so check the minimum width on the product page.

Stainless steel or composite?

Stainless steel is tough, takes hot pans and shrugs off most stains, though it shows water marks and fine scratches as it ages. Granite composite has a matt, stone-like finish that hides marks well and makes a strong contrast against a pale worktop. Both clean with a soft cloth and mild washing-up liquid.

Before you buy

  • Measure the base cabinet. The product page gives the smallest cabinet width the sink needs, and the overall sink size for your fitter’s cut-out.
  • Check your worktop. Undermount sinks need a solid worktop such as stone, quartz or solid surface, so the cut edge can be sealed and polished.
  • Plan the services. Agree where the water supply, waste and tap will run with your fitter, especially for a two-bowl sink with a single waste.
  • Book your fitter. The sink is fitted with the worktop, so agree the cut-out with your kitchen fitter or worktop supplier before they start.

Sinks: your questions answered

What is an undermount sink?

It is a sink fixed beneath the worktop rather than dropped in from above. There is no rim on the surface, so the worktop is easy to wipe down.

What sizes do your sinks come in?

From a compact single bowl for a narrow cabinet to a wide two-bowl sink. Each product page gives the overall size and the smallest base cabinet it needs.

Is a tap included?

The sinks here are listed as the sink alone, so you choose the tap. Any of our kitchen taps will suit, including a boiling water tap; check the tap’s reach suits the bowl.

Can I fit an undermount sink under a laminate worktop?

Usually not. Undermount sinks need a solid, water-resistant worktop such as stone, quartz or solid surface. Ask your worktop supplier if you’re unsure.

Is a granite composite sink easy to look after?

Yes. It resists scratches, heat and stains, and water runs off it well. A wipe with a soft cloth and mild washing-up liquid is usually enough.

Should I choose a stainless steel or granite composite sink?

Stainless steel is hard-wearing and suits most kitchens, but shows water marks. Granite composite has a matt, stone-like finish that hides marks and gives a darker, bolder look.
