The Company Behind the Brand

Neolith is the flagship product of TheSize Surfaces, a Spanish manufacturer based in Almazora in the province of Castellón. When people talk about Neolith they are really talking about TheSize, the company that took the idea of sintered stone and turned it into a surface for kitchens, bathrooms and buildings around the world.

Knowing who makes a worktop matters. The manufacturer controls the recipe, the technology, the quality checks and the warranty. A brand with a long track record, strong investment in research and a clear commitment to sustainability gives you far more confidence than an unknown name. This guide looks at where TheSize came from, what it has achieved and why its reputation matters when you choose Neolith for your home.

For homeowners in Bedford and across the region, it also explains why buying from an established supplier who works with genuine Neolith slabs is so important.

A Short History of TheSize

TheSize Surfaces was established in 2009 by the Esteve family, whose members brought more than 40 years of experience in the natural stone industry. Their goal was to design and produce large format sintered surfaces that combined the beauty of stone with the technical performance of advanced ceramics. The first Neolith slabs were launched in 2010 and quickly attracted attention from architects and designers.

The company chose Castellón deliberately. The province is the centre of the Spanish ceramics industry, with generations of expertise in pressing, firing and glazing. Building its plant there gave TheSize access to skilled people, specialist suppliers and a deep pool of technical knowledge. The timeline below shows some key milestones.

How TheSize Grew Into a Global Name

From a single Spanish plant, TheSize built a distribution network reaching more than 80 countries. Investment firm Investindustrial supported the business during a period of expansion, with the company employing around 550 people according to the investor’s own summary. In North America alone the brand lists more than 55 distribution points, alongside networks across Europe, the Middle East and Asia Pacific.

Neolith surfaces have been used on building facades, in hotels and restaurants, in high end retail and in countless private kitchens. That breadth of use reflects the versatility of the material, which can be cut thin enough for cladding and furniture or supplied in thicker formats for demanding worktops.

Innovation at the Core

TheSize has built its reputation on technical innovation. Its sintering process presses natural minerals at up to 400 bars before firing them above 1,200°C. On top of that, the company has developed a series of proprietary technologies that shape the look and feel of every slab.

These developments have helped Neolith stay ahead in a category that now includes several competing brands. Each innovation addresses a practical concern, such as how a mitred edge looks or how a matt surface feels, rather than simply adding marketing claims.

A Strong Focus on Sustainability

Sustainability is central to how TheSize presents itself. Neolith slabs are made from 100% natural raw materials and are fully recyclable. Some colours contain up to 98% recycled material. The company reports that all of its electricity comes from renewable sources, that its process water is recycled and that more than 96% of its industrial waste is recycled or reused.

It also holds independent certifications, including a Bureau Veritas Zero Waste certificate at Excellent level and an EcoVadis Gold rating. In 2024 it announced silica free formulations, a move aimed at making fabrication safer for the craftspeople who cut and shape worktops.

Why the Manufacturer Matters to You

The reputation of TheSize brings real benefits for homeowners. Consistent quality means the slab you see in a showroom should closely match the one delivered for your kitchen. A long established brand is also more likely to support its products with a meaningful warranty, which is typically honoured when slabs are bought and installed through authorised channels.

It is worth being cautious about lookalike products. The popularity of Neolith has led to many cheaper sintered surfaces that borrow similar design names. These can vary widely in quality. Buying from a supplier who can confirm the slab is genuine Neolith protects both the look and the long term performance of your worktop.

What TheSize Means for UK Homeowners

For a household in Bedford or Milton Keynes, the story of a Spanish manufacturer may seem distant. In practice it shapes your experience in very real ways. Consistent manufacturing means colours and patterns are predictable, so the slab you approve at the showroom should be what arrives for your kitchen. Detailed technical data from the manufacturer helps fabricators plan cut outs, supports and joins with confidence.

An established brand also brings continuity. Popular designs tend to remain available for years, which is reassuring if you later want a matching splashback, a utility room worktop or a repair. Lesser known brands may change or discontinue designs with little notice.

Finally, a respected manufacturer gives your installer a reputation to uphold. Authorised fabricators work to the standards the brand expects, which helps protect the quality of your finished kitchen and the value of the investment you have made.
