Is Neolith Right For You?

Neolith surfaces are well suited for kitchen worktops, bathroom vanity tops, splashbacks, feature walls, commercial surfaces and outdoor kitchens. The range is highly stain-resistant, scratch-resistant, heat-resistant and exceptionally hard-wearing, making it a practical choice for busy households and high-traffic areas. With strong UV resistance, these surfaces are also suitable for areas with direct sunlight — including conservatories and south-facing kitchens. No sealing is required, keeping ongoing maintenance simple.

About Neolith

Neolith is a range of ultra-compact sintered stone surfaces manufactured by TheSize Surfaces S.L. in Castellon, Spain. Created by sintering natural minerals, clays, feldspar and silica at 1200 degrees Celsius under extreme pressure, Neolith delivers extraordinary performance across every measure that matters in a kitchen or bathroom worktop. The surfaces are completely non-porous, require zero sealing, and resist stains, scratches, heat, and UV damage with equal confidence. Available in slabs up to 3200 by 1600mm and in thicknesses from 3mm wall cladding panels to substantial 20mm worktops, the range encompasses 64 designs across six collections including the marble-inspired Classtone, the bold metallic-effect Iron series, the natural wood-look Timber range, and the pure-colour Colorfeel palette. Every Neolith surface is backed by a 25-year warranty and is certified food-safe, making it one of the most versatile and durable surface materials available to UK homeowners. At In2stone, we supply and install the complete Neolith range with expert stonemason craftsmanship and transparent pricing.

Frequently Asked

Questions About Neolith

What is Neolith sintered stone?
Neolith is an ultra-compact sintered stone surface manufactured by TheSize Surfaces S.L. in Castellón, Spain. It is created by compressing natural raw materials — including clays, feldspar, silica, and natural mineral oxides — under extreme pressure and then firing them at temperatures exceeding 1,200°C. This sintering process fuses the particles at a molecular level, producing a surface that is completely non-porous, extraordinarily hard, and resistant to stains, scratches, heat, chemicals, and UV radiation. Unlike engineered quartz, which uses resin binders, Neolith contains no resins or artificial additives, making it one of the purest and most durable surface materials available for kitchen worktops, bathroom vanities, wall cladding, and flooring.
How much do Neolith worktops cost in the UK?
Neolith sits within the premium pricing bracket for kitchen worktops, reflecting its advanced manufacturing process and exceptional performance characteristics. The final cost of a Neolith worktop depends on several factors, including the specific design chosen, the slab thickness selected (ranging from 6mm to 20mm for worktop applications), the complexity of the kitchen layout, edge profile detailing, and any cutouts required for hobs and sinks. At In2stone, we provide fully inclusive quotes covering templating, fabrication, and professional installation by experienced stonemasons. We are always happy to discuss your project in detail and provide a transparent, no-obligation quotation tailored to your specific requirements.
Is Neolith better than quartz for kitchen worktops?
Neolith and engineered quartz are both excellent worktop materials, but they differ in several important ways. Neolith offers superior heat resistance — you can place hot pans directly on the surface without risk of damage, which is not recommended with most quartz surfaces. Neolith also delivers better UV resistance, meaning it will not yellow or discolour when exposed to direct sunlight, making it suitable for outdoor kitchens and conservatory installations where quartz would struggle. Additionally, because Neolith contains no resin binders, it achieves a harder, more scratch-resistant surface. However, quartz typically offers a wider colour range at lower price points and is available from a greater number of suppliers. The best choice depends on your priorities, budget, and how you use your kitchen.
Do Neolith worktops need sealing?
No, Neolith worktops never need sealing — not at installation and not at any point during their lifetime. Because the sintering process creates a completely non-porous surface with zero water absorption, there are no microscopic pores or channels for liquids, bacteria, or stains to penetrate. This is one of Neolith's most significant practical advantages over natural stone surfaces like granite and marble, which require regular sealing to maintain their stain resistance. With Neolith, the surface you install on day one performs identically twenty-five years later, with no maintenance treatments, no resealing, and no specialist cleaning products required.
What warranty does Neolith offer?
Neolith surfaces are backed by a comprehensive 25-year warranty that can be registered online after installation. This warranty covers manufacturing defects and provides homeowners with long-term peace of mind that their investment is protected. The warranty reflects the genuine durability of the sintered stone manufacturing process — Neolith surfaces are designed to last the lifetime of a kitchen without degradation in appearance or performance. At In2stone, we also stand behind the quality of our fabrication and installation work, ensuring that your Neolith worktop is fitted to the highest professional standards.
Can Neolith be used outdoors?
Yes, Neolith is one of the very few worktop materials that is genuinely suitable for outdoor use. Its complete UV resistance means it will not fade, yellow, or discolour when exposed to direct sunlight over extended periods — a significant advantage over engineered quartz and many other surface materials. Neolith is also resistant to freeze-thaw cycles, meaning it will not crack or delaminate in cold British winters. This makes it an excellent choice for outdoor kitchens, barbecue areas, garden bars, and patio dining surfaces. The 3mm and 6mm formats are also widely used for external wall cladding and facade applications, where their weather resistance and dimensional stability provide long-term architectural performance.
How do you clean and maintain Neolith worktops?
Neolith worktops require remarkably little maintenance. For everyday cleaning, simply wipe the surface with a damp cloth or sponge and a mild household soap or detergent — that is genuinely all that is needed. Because the surface is completely non-porous, spills cannot penetrate and stains cannot form, so there is no need for specialist stone cleaners, sealants, or protective treatments. For stubborn marks, a non-abrasive cream cleaner can be used without risk of damaging the surface. Avoid using abrasive scourers or steel wool, as these can dull certain finishes over time — although the stone itself will not be damaged. The surface is also naturally hygienic and food-safe, as bacteria cannot colonise the non-porous surface.
What collections does Neolith offer?
The Neolith range is organised into six distinct collections, each with its own design identity. Classtone features marble-inspired designs that replicate the beauty of Calacatta, Statuario, and other prestigious natural marbles. Fusion offers a diverse range of natural stone, concrete, and textured surfaces inspired by geological formations from around the world. Colorfeel delivers pure, solid colours in pristine whites, creams, and blacks for minimalist design schemes. The Iron collection captures the distinctive character of oxidised and brushed metals in surfaces ranging from warm copper to cool gunmetal. Timber recreates the warmth and grain of natural wood without any of its maintenance demands. Finally, the Iconic Design collection presents statement surfaces of extraordinary visual drama. Together, these collections offer over sixty unique designs covering virtually every aesthetic preference.

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!"
