The quick verdict

If you want the widest possible choice of colours and veining at a slightly lower price, for a strictly indoor kitchen, quartz is superb. If you want maximum heat and scratch resistance, a surface that can also go outdoors, and a through-body look, Dekton has the edge. Both are excellent; the right answer depends on how you use your kitchen.

What each one is

Quartz worktops are made from roughly 90% or more crushed natural quartz bound with around 7 to 10% polymer resin and pigments. That resin is what holds the slab together and gives quartz its consistency, but it is also the source of its main limitation around heat and sunlight.

Dekton is a sintered ultracompact surface made by Cosentino from a blend of around twenty minerals, with no resin, fused under extreme heat and pressure. The lack of resin is the key difference, and it is why Dekton tolerates heat and ultraviolet light so well.

Dekton vs quartz, side by side

Heat: the biggest practical difference

This is where the two really diverge. Because Dekton contains no resin, you can place hot pans on it without fear of scorching, and it is even used for fireplace surrounds and outdoor cooking areas. Quartz, by contrast, can discolour or develop a mark if a very hot pan is left directly on it, because the resin binder reacts to high heat. With quartz, a trivet is essential; with Dekton it is simply good practice. Our guide on whether Dekton is heat resistant goes into detail.

Indoors or outdoors?

If you dream of an outdoor kitchen or a sunny garden bar, Dekton is the clear choice. It is completely stable under ultraviolet light, so its colour will not fade, and it resists frost. Quartz is designed for indoor use; prolonged sunlight can cause some quartz colours to fade over time. For anything outside, Dekton wins comfortably, as covered in our guide to Dekton for outdoor kitchens.

Looks and feel

Both materials offer marble effects, solid colours and concrete looks. Quartz arguably still leads on the sheer breadth of dramatic veined designs, and some people prefer its slightly warmer feel underhand. Dekton offers striking designs too, often with colour that runs through the body of the slab, which keeps mitred edges looking consistent. Browse popular Dekton colours to see the range.

Price and value

Quartz typically costs a little less than Dekton when supplied and fitted, though the ranges overlap and a premium quartz can match a mid-range Dekton. Both are long-lasting, low-maintenance investments. If budget is the deciding factor and the kitchen is indoors, quartz makes sense; if you want the ultimate in resilience and outdoor capability, Dekton justifies its premium. See our cost guide for figures, and 0% finance is available either way.

How they are fabricated

One practical note: Dekton is harder and more demanding to cut than quartz, requiring diamond tooling and careful handling, which is part of why it costs a little more to fabricate. Quartz is slightly more forgiving in the workshop. Either way, the skill of your fabricator matters, and we cut both in-house. See how Dekton is cut and fabricated.

Hygiene and food safety

Both Dekton and quartz are non-porous, which is good news for hygiene. With no pores for liquids or bacteria to penetrate, neither surface harbours germs in the way a porous, unsealed stone can, and both are easy to keep clean with everyday products. For food preparation, both are safe and practical, though a chopping board is wise on either to protect your knives and the surface. This is one area where the two materials are genuinely equal.

Designing with each

Dekton’s large-format slabs, up to around 3.2 metres, mean fewer joints across long runs and islands, and because colour often runs through the body, mitred and waterfall edges look seamless. Quartz also comes in generous slab sizes and offers some of the most dramatic veined patterns available, which can make a real statement on an island. If your design hinges on a particular bold vein or a specific shade, the determining factor may simply be which material offers the exact look you want.

Longevity and resale

Both materials are long-term investments that can comfortably outlast the rest of a kitchen and add appeal for future buyers. Dekton’s 25-year manufacturer warranty and outdoor capability are attractive selling points, while quartz’s familiarity and colour range are widely loved. Whichever you choose, a quality engineered surface fitted well is a feature that holds its value, and our guide on whether Dekton worktops are worth it explores this further.
