What type of sink do I need for a granite worktop?


When you decide on buying a granite worktop then you can still choose from a wide range of sinks. The 3 types of sinks that you have to choose from are shown below, with a brief explanation.

Undermounted Sink

An undermounted sink is just that. It is placed into a kitchen unit that allows the sink to sit underneath the granite worktop. This allows you to get the most from your granite and see the shiny edges that drop off into the sink.

The other benefit of a granite worktop is that you do not need to buy a draining board. This is because you can have the draining board grooves cut straight into the granite worktop, giving you a stylish worktop as well as more work space when required.

Inset sink

An inset sink is a sink the sits on top of the granite worktop complete with draining board. The hole for the sink has to be cut out of the granite, as well as the taps, so you need to ensure you know what sink and tap you are going to have before the granite is cut to size and with the cut-outs required.

Belfast sink

A Belfast sinks rest upon a kitchen unit and butts up to the underside of the granite. This can look very effective with a contrasting granite worktop.

There are some more examples below to see how a Belfast sink could look in your kitchen with a granite or solid surface worktop.

Personally, if I was making an investment in a granite worktop then I would opt for the undermount or Belfast sink with the draining board groves cut into the worktop. It looks very stylish and the draining area is so much easier to clean than the traditional stainless steel ones that many kitchens have.

    I want to use a composite/granite undermount sink, underneath a quartz worktop. I understand the fitters will seal in the sink. I believe I need a bracket to brace the sink to take the weight? Where do I get these from, I’ve seen one in your showroom and a picture of it on your help pages but I’ve no idea where to purchase?

      Hi, we would advise that a support is fitted to the underside of the sink after installation but this can be done with either an additional shelf or simply a baton to the underside.

      Hi, if you have the under mount sink on site when the suppliers come to install the worktop then the sink will be fitted and bonded to the worktop. What you would need to do is plum the sink in.

    Can you tell me if grooves on a granite worktop for draining are usually pre cut at the Factory or on site ?

      When you arrange for a granite worktop to be fitted the 1st stage is templating where some people come to your home and measure up for the worktop lengths and cut-outs (& drainer). All the cutting and modifications to the worktop are done at the factory, so that when the worktop is delivered, all that remains is the fitting.

    there seems to be quite a difference in price on undermount sink brands, is there any reason not to buy a cheap undermount sink? difference in steel quality, leading to leaks etc? they all seem similar designs.

      Hi, prices of stainless steel sinks do vary considerably in price. The main reason is the quality of the steel. Cheaper sinks are more prone to rust spots and scratching over time, but there is usually more longevity with the more expensive sink, which is normally a thicker grade steel with a higher aluminium content.

      Franke is a market leader in the making of sinks and is a well known brand. It is worth paying the extra or researching the quality of the sink that you wish to buy. There is considerable work in removing an undermounted sink and fitting a new one and resealing it in position. For peace of mind I would suggest buying a recognised brand, after all the sink is used many times per day and is a vital part of any working kitchen.

    if i buy an undermounted sink & quartz worktop (with fitting) from you will the fitter install the sink?

      The people that measure, template and fit the quartz worktop will fit the undermount sink into position, glue and seal it around the edges for you. You will however need a plumber to do all the plumbing work.

      Hi Gary,
      Yes you can use a Belfast sink with a granite worktop. Hopefully we will have these worktops on our website in the next few weeks with a quote calculator that will allow you to add tap holes & drainers etc. Prices vary Group 1 granite is £133.10 per sqm & Group 10 granite is £533.30 per sqm.
