Dekton Umbra Description: Raw Clay With Zero Porosity
The name Umber derives from the Italian ‘terra d’ombra,’ which translates as “earth of Umbria”, a mountain region in Italy where the mineral was first discovered.
Dekton Umber takes inspiration from this raw clay in a brown earth colour comprising natural minerals, known as ‘raw umber’, and blends it with modern sintered stone technology. As a result, the surface is non-porous, unaffected by sunrays, and highly resistant to scratches and burns.
This surface has a reddish-coloured body. Thus, the shade of the worktop is consistent throughout.
The ultra-compact surface comprises zero porosity, making them stain and water-resistant—ideal for modern and traditional styles.
The beauty and functionality of Dekton Umber worktops.
This sintered stone is influenced by raw clay, which offers a natural crimson tint and modern technology, providing a non-porous, scratch-resistant, and UV-protected surface.
Umber is part of an environmentally conscious collection with a focus on sustainability. Explore its large sizes, thickness options, and matte finish. Benefit from its durability, stain resistance, and effortless maintenance, making it the perfect addition to any kitchen.
Dekton Worktops Vs. Quartz
Explore the nuances between Dekton and quartz, two popular choices for worktops and splashbacks.
- 1. Dekton stands out with its unparalleled stainproof quality, offering superior resistance to staining compared to stain-resistant quartz.
- 2. Dekton is fireproof and highly heat-resistant, making it ideal for outdoor use and direct contact with heated cookware. In contrast, quartz is susceptible to heat and sunlight, leading to potential discolouration.
- 3. Dekton takes the lead in UV protection, remaining unfazed by sunlight exposure, while quartz, particularly in darker shades, may experience colour changes.
- 4. Both materials boast scratch resistance, yet Dekton, with its subtle matte finish, is more prone to chipping upon strong impact, unlike the glossy finish of quartz.
- 5. Dekton is highly impact resistant, but quartz is a more flexible surface, offering high impact resistance.
Choose Dekton for superior stain resistance, heat resistance, and UV protection, or opt for quartz for impact resistance and a broader spectrum of colours and patterns, considering your specific needs and aesthetic preferences.

Dekton worktops provide numerous advantages for both home and office environments. They meet all technical criteria to transform any interior or outdoor design into a highly durable surface.
A Wide Range of Colours
With fifty different colours across seven collections, Dektonworktops offer endless combinations of colour, finish, and thickness. Whether you prefer traditional or contemporary designs, the seven collections—Natural, Tech, Solid, Industrial, Liquid, and Stonika—cover every design style and theme.
Scratch and Abrasion Resistant
Dekton countertops offer superior scratch and abrasion resistance, with a wear volume average abrasion of 116 mm3. This makes them almost 5.5 times more resistant than marble, with an abrasion wear of 22.23 mm3, making them ideal for high-use areas.
Unrivalled Thermal Shock Resistance
Unlike natural stones like marble and granite or engineered stones like quartz, Dekton worktops withstand extreme temperature changes. They can handle up to 300 degrees Celsius, letting you place hot items directly on the surface without fear of cracking, burning, or scorching.
Fireproof
Dekton is rated Class A1 according to the UK's BS EN 13501-1 regulation, the highest performance rating for fire resistance. This means it can tolerate direct contact with heated cookware and devices without getting burned, ensuring your kitchen remains safe and durable.
Easy to Clean
Unlike other materials, a Dekton kitchen worktop isn't affected by bleach or acids. Spray any household cleaner on the surface for quick clean-ups, making it perfect for kitchen and bathroom areas where messes are frequent.
Low Maintenance
One of Dekton's biggest advantages is its low maintenance. The surface doesn't require sealants, additional coatings, primers, or enhancers, which translates to significant time and cost savings over other worktop materials that demand regular upkeep.
Stain Resistant
Dekton can withstand common kitchen ingredients like wine, turmeric, coffee, lemons, and ketchup, ensuring your work surface remains pristine. Use a spray like Windolene or water and neutral soap for daily cleaning.
Dimensional Stability
Dekton's large slab sizes of 3200 x 1440 mm allow for efficient planning and installation, reducing material waste and cost. The slabs expand minimally, ensuring tight seams between worktops.
High Mechanical Strength
The pressing process, with up to 25,000 tonnes, gives Dekton its unmatched mechanical strength. Its compactness offers versatility in five thickness options, making it suitable for areas requiring high-impact resistance.
UV Light Resistance
Ideal for indoor and outdoor applications, Dekton worktops are highly resistant to UV light, ensuring they do not fade or deteriorate over time.
High Resistance to Hydrolysis
Dekton's superior resistance to hydrolysis makes it perfect for application in bathrooms, spas, and outdoor pools. The surface does not split or deteriorate, ensuring long-term durability.
Resistant to Freezing and Thawing
Designed to withstand diverse weather conditions, Dekton's resistance to freezing and thawing ensures it performs exceptionally well, even in extreme climates.
CHEMICAL FORMULATION
Because this stone contains no resins or organic ingredients, Dekton does not employ a polymerisation process during its manufacture, and its chemical makeup is entirely inorganic.
In addition, DEKTON uses several formulas that vary according to the surface type, meaning that the final chemical structure can change without affecting its chemical or physical qualities.
Aluminium silicates, amorphous silica, crystalline silica, zircon, and inorganic colours are a few examples of DEKTON's chemical makeup. The crystalline silica component in all colours and formulations is always less than 11% by weight.

COLOUR AND TONES
Cosentino assigns numbers to describe tones in the colours (slight changes in colour intensity), and each slab is defined by Colour & Tone.
Here are the factors that determine Dekton colours and tone variation:
- Colours in solids: E variant (control with) The slab unit label with Colour and Tone Code reflects the colour and tone.
- The label determines the slab's tracing and history. As it progresses through the industrial manufacturing operation, it is sent via the slab number (batch).
- Spectrophotometer settings: Lab/D65/10o).
- Colours with veins: visible differences (of pattern)
Dekton: 25-year warranty
Besides technical superiority, originality, and style, Dekton offers a 25-year warranty on its designs.
You need to provide your invoice/receipt when filling out the Dekton warranty form within 6 (six) months of your purchase to activate your warranty.
If you don't activate your warranty within this period, you will enjoy the same benefits for 2 (two) years.
Dekton Umber slabs measure up to 323x147 cm and offer a usable area of 320x144cm.
Dekton Umber offers two finishes: a standard matte texture and a grooved slab with the Ukiyo finish.
While both Dekton and Neolith are ultra-compact surfacing materials with high durability and resistance, their slab sizes, thicknesses, finishes, and composition differ. The choice between the two may depend on specific needs, such as thicknesses, finishes, designs, and aesthetic preferences.
