About Dekton

Dekton is Cosentino's ultracompact sintered stone surface, engineered using TSP technology that applies 25,000 tons of pressure to compress over twenty natural minerals into a surface of null porosity. This revolutionary process perfects in hours what nature creates over thousands of years, producing a material that outperforms natural stone, porcelain, and quartz in virtually every performance measure. With complete resistance to stains, scratches, UV light, fire, and extreme temperatures, Dekton is equally at home on a kitchen worktop as it is on an exterior building facade. Our collection of over 45 Dekton colours spans the full breadth of contemporary design — from hyper-realistic marble reproductions in the Stonika and Pietra Edition collections to raw industrial textures in the Kraftizen range, dreamlike artistic veining in the Onirika collection, and coastal-inspired whites in the Silverkoast range. As the world's first cradle-to-grave carbon neutral surface, Dekton delivers premium performance with genuine environmental responsibility. At In2stone, our skilled craftsmen fabricate and install Dekton with precision CNC cutting and invisible joins — bringing this extraordinary material to kitchens, bathrooms, and living spaces across Portsmouth, Hampshire and the surrounding area.

Frequently Asked

Questions About Dekton

What is Dekton and how is it different from other worktop materials?
Dekton is an ultracompact sintered stone surface manufactured by Cosentino using their proprietary TSP (Technology of Sintered Particles) process. This process compresses over twenty natural minerals under 25,000 tons of pressure — 2.5 times the weight of the Eiffel Tower — creating a surface with null porosity that is virtually indestructible in everyday use. Unlike quartz, which uses resin binders, Dekton is created through extreme heat and pressure alone, making it fire-resistant (A1 certified), UV-stable, and suitable for both indoor and outdoor applications. Compared to natural stone, Dekton never needs sealing, won't stain from wine or coffee, and won't etch from acidic substances like lemon juice. It's arguably the most advanced surface material available for kitchen worktops in the UK today.
Is Dekton suitable for outdoor kitchens and exterior use?
Absolutely — Dekton is one of the very few worktop materials that performs flawlessly outdoors. Its complete UV resistance means colours never fade, even in direct sunlight over many years. Its null porosity ensures it won't absorb rain water, and its frost-resistant properties prevent cracking in cold weather. Dekton's A1 fire certification also makes it ideal for BBQ surrounds and outdoor cooking areas. This combination of properties is why Dekton is used for building facades and exterior wall cladding worldwide — the same performance that protects skyscrapers also protects your garden kitchen worktop.
How does Dekton compare to natural marble for kitchen worktops?
Dekton offers several significant advantages over natural marble while capturing much of its visual beauty. Collections like Stonika and Pietra Edition feature hyper-realistic marble reproductions that rival the genuine article in terms of veining depth and mineral character. However, unlike marble, Dekton will never stain from red wine, coffee, or cooking oils; never etch from acidic foods like lemon juice or vinegar; and never require periodic sealing or special cleaning products. Marble rates around 3 on the Mohs hardness scale, while Dekton rates approximately 8, meaning scratches from daily kitchen use are virtually impossible. For homeowners who love the marble aesthetic but want zero-maintenance performance, Dekton is the ideal solution.
Does Dekton need to be sealed, and what maintenance does it require?
Dekton requires no sealing whatsoever — not at installation, and not at any point during its lifetime. This is because the TSP manufacturing process creates a surface with null porosity, meaning there are literally no microscopic pores for liquids to penetrate. Daily maintenance is simply wiping with warm water and a mild soap or detergent. For stubborn stains, standard household cleaning products are perfectly safe to use. There are no special stone care products needed, no annual resealing appointments, and no restrictions on what you can place on the surface. This makes Dekton one of the lowest-maintenance premium worktop materials available.
What warranty does Dekton come with?
Dekton comes with a comprehensive 25-year warranty from Cosentino, covering manufacturing defects and product performance. This is one of the longest warranties in the premium worktop industry and reflects Cosentino's confidence in Dekton's durability. The warranty covers domestic installations and is backed by Cosentino's global infrastructure — one of the world's largest surface manufacturers with a presence in over 80 countries. When you purchase Dekton through In2stone, we register your warranty and handle any claims directly with Cosentino on your behalf.
Is Dekton environmentally friendly?
Dekton holds a unique distinction in the surface industry: it is the world's first cradle-to-grave carbon neutral surface. This means Cosentino offsets 100% of CO2 emissions across Dekton's entire product life cycle — from raw material extraction through manufacturing, distribution, installation, use, and eventual end-of-life. The manufacturing process uses 100% renewable electricity, and Cosentino invests in verified GHG emission offsetting projects. The company's carbon footprint is calculated and verified by accredited third-party organisations. For environmentally conscious homeowners, Dekton offers the rare combination of exceptional performance and genuine sustainability credentials.
What sizes and thicknesses is Dekton available in?
Dekton is available in large-format slabs measuring 320 x 144 cm, which allows for expansive worktop installations with minimal joints — ideal for creating visual continuity across large kitchen islands. It is also available in a smaller 71 x 71 cm format. Thickness options include 30mm and 20mm for worktops, 12mm and 8mm for wall cladding and furniture applications, and the ultra-slim 4mm Dekton Slim format designed specifically for lightweight vertical cladding and furniture surfaces. The Optimma format (260 x 100 cm in 4mm thickness) is specially optimised for the most common vertical cladding applications.
Can In2stone supply and install Dekton worktops?
Yes — In2stone is a specialist supplier and installer of Dekton worktops serving Portsmouth, Hampshire, Sussex, Surrey, Dorset and Berkshire. Our experienced stonemasons are fully equipped to template, fabricate, and install Dekton using precision CNC cutting technology, ensuring perfect fits with invisible joins. We work with you from initial design consultation through to final installation, including sink cutouts, hob recesses, drainage grooves, and edge profiles.

What Our Customers Say

★★★★★
"Excellent Service and Beautiful Results - Highly Recommended! I recently had In2stone install new quartz worktops in my kitchen, and I couldn't be happier with the results. From start to finish, the experience was completely stress-free. The team was not only competitively priced but also incredibly friendly and professional throughout the entire process. They handled everything seamlessly - removing the existing sink, hob, and old laminate worktops before fitting the new quartz surfaces. The finished worktops are absolutely beautiful and have transformed my kitchen into a modern, minimalist space that I love spending time in. The quality of workmanship is outstanding, and the attention to detail really shows. I'm a very satisfied customer and would highly recommend In2stone to anyone considering new worktops. Well done to the entire team - you've exceeded my expectations!"
