From format to application: guide to Atlas Plan slab thicknesses
In contemporary design, the choice of porcelain stoneware thickness is an integral part of the project: it is not just a technical detail, but an element that directly affects performance, safety, aesthetic appeal and application possibilities.
Atlas Plan slabs are designed to meet advanced design requirements and are available in three large formats designed to expand the compositional possibilities.
The large unrectified tiles are available in sizes 162x324 and 159x324, designed to ensure maximum freedom in the creation of various furnishing elements: kitchen tops and backsplashes, washbasin tops and integrated washbasins, worktops, tables, desks and counters, as well as solutions such as ventilated facades. These are complemented by the 160×320 cm rectified format, characterised by a wide range of graphic variations, ideal for floors, wall coverings or elements with a high visual impact, where precision and visual continuity are central elements of the project.
Three thicknesses, multiple design possibilities
Atlas Plan offers porcelain stoneware slabs in three main thicknesses – 6 mm, 12 mm and 20 mm – each designed for specific uses. This range allows you to choose the most suitable solution based on the type of surface, the expected load and the installation environment. Using the same material in different areas of the project allows you to maintain aesthetic consistency and optimise technical performance.

In the kitchen, the thickness of the porcelain stoneware is crucial to ensure long-term reliability and safety of use. Worktops and islands are subjected to daily impact, heat and stress, which is why 12 mm and 20 mm thicknesses are the ideal choice.
Large slabs allow for the creation of continuous surfaces, where aesthetic versatility and technical performance converge.


In the bathroom, the 6 mm thickness is ideal for vertical coverings. The lightness of the slab makes it easier to install and allows you to create continuous surfaces on walls, niches and shower areas, enhancing the perception of space.
The use of large slabs reduces visual interruptions and facilitates maintenance, a particularly important aspect in humid environments.




In living rooms and day areas, the choice of thickness is often guided by aesthetic as well as functional requirements. The 6 mm and 12 mm thicknesses allow walls, fireplaces, architectural volumes and decorative surfaces to be clad without weighing down the space.
In these contexts, the slabs become true design elements, capable of interacting with other materials such as wood, metal and glass, where material and architecture merge into a single language.

For outdoor applications, the 20 mm thickness guarantees the necessary strength to withstand atmospheric agents, temperature changes and structural stresses. It is the ideal solution for façades, skirting boards and surfaces that require high performance.
Using the same material indoors and outdoors creates visual continuity between rooms, reinforcing the design concept and enhancing the architecture as a whole.

Choosing the thickness of the porcelain stoneware is a fundamental step in transforming a design idea into a concrete, functional and durable solution. Thanks to the variety of sizes and thicknesses available, Atlas Plan slabs allow you to tackle any application with technical expertise and creative freedom.
