A worktop is usually chosen after the fronts and ordered only once the base units are in, because the stonemason templates it on cabinets that are already standing in the kitchen. That’s often when a question from the consultation comes back: a pale worktop with grey veining should look the same in five years, even though four people cook in this kitchen every day. Marble can give that look, and so can quartz or sintered stone, but each reacts differently to a hot pan, lemon juice and a frying pan knocked against the edge.
Natural stone covers several different materials
Natural stone is a label for materials that behave differently in a kitchen. Granite is hard, has a grainy pattern with visible crystals and takes hot pans. Marble has soft veining that runs through the whole slab, but acids etch it: lemon juice, vinegar, wine or tomato sauce leave dull marks on a polished surface. Limestone and travertine react the same way and soak up liquids as well. Quartzite is harder than marble, but stone that also reacts to acid sometimes gets sold under that name. Before ordering, test a sample with a drop of vinegar: if it leaves a dull mark after a few minutes, the stone will behave like marble in your kitchen.
Every slab has its own pattern, and a small sample can’t show how the veins will fall across a whole worktop. That’s why you look at the slabs at the stone yard before they’re cut. Stone needs sealing, and how often depends on the type: when a drop of water leaves a dark patch after a few minutes, it’s time to reseal. A stonemason can grind out dull patches and scratches and repolish them on site, without taking the worktop out.
Granite and marble are heavy, so the cabinets under a long run or an island need to be built for the load. The price depends on the stone: common granites cost about the same as quartz, while rare marbles and quartzites are among the most expensive worktops.
Quartz composite has a repeatable pattern
Quartz composite is quartz aggregate bound with resin and pigments and pressed into slabs. The pattern is even and repeats, so a sample from our workshop gives a fair idea of the whole worktop. The colour runs through the full thickness, usually 2 or 3 cm, so the edge can be rounded or chamfered and drainer grooves can be routed next to an undermount sink. Coffee, wine and oil don’t soak in, so it doesn’t need sealing. It’s also less brittle than sintered stone, and a stonemason can fill a small chip with resin tinted to match.
The resin is the weak point. A hot pan put down without a trivet can leave a permanent pale mark or even crack the slab, so keep a board or trivet next to the hob. Years of strong sun change the colour of the resin, which rules quartz out for a terrace or an outdoor kitchen. Oven cleaners, drain unblockers and solvents dull and discolour the surface.
Sintered stone contains no resin
Sintered stone is made in a different way from quartz: a mix of minerals is pressed and fired at high temperature, with no resin at all. That’s why hot cookware leaves no mark on it, the surface doesn’t absorb stains or need sealing, and the colour holds in sunlight. It works by large glazed walls and outdoors as well.
Sintered slabs are thin, often 12 mm, and the same material can clad the wall behind the worktop or the side of an island. In many slabs the marble, concrete or stone pattern sits only on the surface, and the body is a different shade. So the edges stay square with a small chamfer, or the stonemason mitres them at 45° to make the worktop look thicker. A rounded edge or routed drainer grooves would expose the body of such a slab.
Sintered stone is hard, and brittle with it. A heavy pan knocked against an edge or corner can chip it, and a resin repair stays visible. Glasses break more easily on such a hard surface, and knives blunt quickly, so a chopping board is a must. Grey streaks from the bottom of a pan are usually traces of metal that come off with a gentle cream cleaner. Fabricating sintered stone takes a stonemason longer than quartz, so the finished worktop costs more.
Joints, cut-outs and thickness
Slabs of stone, quartz or sintered stone only come so long, so a long run or an L-shaped kitchen usually needs a joint. We decide where the joint goes at the design stage, away from the sink and hob, where it would take the most water and heat. The stonemason polishes the cut-outs for an undermount sink and an induction hob and rounds their inside corners, because a sharp corner cracks more easily. Thin sintered stone looks light, while 3 cm of granite or quartz gives the worktop a heavier edge.
Worktops compared in a table
We give cost in relative terms, as the final price comes down to the type of stone, its thickness, the number of cut-outs and the length of the worktop.
| Material | Look | Durability | Care | Relative cost |
|---|---|---|---|---|
| Granite | grainy pattern with crystals, every slab different | high: takes hot pans, hard to scratch; porous types soak up oil unless sealed | pH-neutral cleaner, sealing as the type requires | varies by type; common granites about the same as quartz |
| Marble | soft veining through the slab, patina with age | low: acids etch it and it scratches easily | wipe up acids at once, regular sealing, coasters under glasses | high; rare types among the most expensive worktops |
| Quartz composite | even, repeating pattern, colour through the full thickness | high against stains, lower against hot pans and sun | soapy water, trivets under pans, no harsh chemicals | medium |
| Sintered stone | any pattern, in many slabs only on the surface | high against heat, stains and sun; brittle edges and corners | mild detergent and water, no sealing | high, usually above quartz |
Matching the worktop to the kitchen and the household
A family with small children
Spilt juice, crayons and toy bricks banged against the edge come with the territory. A mid-toned quartz with a light fleck hides marks well, resists stains, and a chip can be filled. Sintered stone handles stains just as well, but its edge takes knocks less kindly, so on an island that children run around we choose an edge with a generous chamfer. Marble in a kitchen like this soon collects dull juice marks.
A kitchen for serious cooking
If you often move pans straight off the hob and put oven trays down on the worktop, sintered stone or granite will serve you better. Both take the heat, and granite handles knocks on the edge better than sintered stone. Quartz works too, as long as there’s always a trivet by the hob. We don’t recommend marble here, because lemon, wine and vinegar will mark it quickly.
A flat to let
Tenants don’t always remember the trivet, and they won’t reseal stone. The safest choice is quartz in a plain, not too dark colour or, on a tighter budget, a compact HPL worktop, which is waterproof all the way through and cheaper than stone.
A kitchen by a big window or on a terrace
Strong sun discolours the resin in quartz, and outdoors there’s frost and rain as well. Here we choose sintered stone, which holds its colour in the sun and doesn’t absorb water.
A classic interior and a taste for patina
Marble makes sense if you like a worktop that shows years of cooking. Dull lemon marks and fine scratches build into a patina over time, and when you want a smooth surface back, the stonemason will repolish it.
Stone, quartz and sintered stone samples sit next to the front samples in our workshop, so you can put a worktop beside your cabinet colour in daylight. Book a visit and bring a photo of your kitchen, or a door sample if you already have one.
