Raquel Martínez, general manager at Alttoglass Group, discusses the different surface material options for modern pool applications
When designing contemporary swimming pools, selecting the right surface is a critical decision where aesthetics, safety, and longevity intersect. As a manufacturer specialising in pool materials, Alttoglass Group produces both glass mosaic and small-format porcelain. This dual perspective allows us to understand that while both offer exceptional durability, they cater to distinct architectural expressions and technical requirements.
Glass mosaic has long been the gold standard for luxury pools due to its unparalleled interaction with light. From a technical standpoint, glass is completely non-porous. This zero-porosity provides an immense practical advantage: it is naturally antibacterial and prevents the growth of mould and algae, ensuring a hygienic environment.
Furthermore, the material has undergone a profound design evolution. Historically limited to flat, solid colours, advanced digital printing techniques are now available that significantly expand design possibilities. This innovation allows for intricate patterns, textures, and shade variations that transform water into a dynamic visual feature, all while wrapping seamlessly around complex curved pool geometries.
On the other hand, porcelain brings a refined architectural language to outdoor spaces, available in numerous sizes to suit diverse project needs. A popular contemporary trend is using large-format tiles to achieve seamless visual continuity from the terrace deck directly into the pool. However, these large formats require flawless technical installation to prevent structural issues under water pressure.
To mitigate these challenges, small-format porcelain options offer a highly versatile alternative. They provide superior structural density, adapt effortlessly to pool shapes, and deliver excellent slip resistance. Today, manufacturing allows us to offer a vast range of finishes and authentic designs—from minimalist surfaces to rich textures—that align perfectly with any aesthetic requirement.
A balanced approach
Ultimately, the choice depends on the desired atmosphere and technical scope. Glass mosaic excels in creating a luminous, highly hygienic finish enhanced by modern printing, while porcelain offers outstanding structural cohesion and finish variety. At Alttoglass Group, our focus remains on driving these innovations forward, ensuring that global design professionals do not have to compromise between technical precision and creative freedom.
