Our Porcelain Stoneware

What is porcelain stoneware?

Porcelain is a type of compact stoneware created from natural raw materials of mineral origin such as clays and feldspars. It is fired at over 1200ºC, resulting in almost zero porosity and such spectacular durability that it has become the product of choice for architecture and construction

Porcelain stoneware is considered to be any ceramic
material with a water absorption coefficient
equal to or less than 0.5%.

The absorption coefficient is particularly important because
it affects the physical properties of the product: the lower the absorption percentage,
the greater the resistance of the material.

All Rosa Gres products are made from porcelain stoneware
with an absorption coefficient of less than 0.1%.

Rosa Gres products have an absorption coefficient lower than that specified
by the standard for the porcelain stoneware category, which
means that they are among the most durable on the market.

Every property of porcelain stoneware provides an advantage for you

Porcelain stoneware is in fashion, find out why


There are no limits to the colors and textures of porcelain stoneware. This allows us to explore every style and create aesthetic finishes that are visually perfect.


With practically zero porosity and water absorption, porcelain stoneware is a highly durable and long-lasting material.


Porcelain stoneware has an extremely high resistance to abrasion. It will not break or scratch. It has high flexural strength and impact resistance. It is one of the hardest materials available.


Porcelain stoneware is not affected by drastic temperature changes, exposure to the sun, extreme cold, frost or snow.


Porcelain stoneware is resistant to chemical cleaning products. This is essential for pool liners which are subject to water treatments.


As an inert and non-porous material, it protects against humidity and the development of microbial colonies and germs.


Unlike wood, marble and other porous materials, porcelain stoneware does not absorb spilled liquids or oils and does not retain dirt.


With just warm water, neutral soap and minimal effort, porcelain stoneware always looks as good as new.


Porcelain stoneware does not change color over time and is not affected by continuous exposure to the sun.

Rosa Gres porcelain stoneware is 100%
manufactured at our plant in Vallmoll, Tarragona.

Integrated manufacturing system

We manufacture all Rosa Gres base pieces using the pressing method to obtain the perfect size and caliber. Thanks to this system, our base pieces can be installed with a narrower joint.

All Rosa Gres special pieces, steps, edges, channels, gratings and half-rounds, are manufactured by extrusion. This allows us to obtain much more robust, resistant and long-lasting pieces.

Unique colors + special pieces

At Rosa Gres, we love to create evocative, inspiring and beautiful colors. At the same time, we focus on designing innovative solutions for the most technically demanding construction projects: pools, terraces, stairs, drainage channels, anti-slip surfaces. We have over 40 years of experience in the creation of complete and functional systems, where each finishing piece plays an essential role. Our special pieces set us apart for their quality and perfection.

The value of Rosa Gres aesthetics

Thanks to our manufacturing system combining pressing and extrusion,
we are able to produce base tiles and special pieces in the same colors.
 This allows us to achieve maximum visual harmony.

Rosa Gres porcelain stoneware is ideal for tiling pools and terraces
 and coordinating indoor and outdoor flooring.
