Porcelain stoneware is a ceramic tile that becomes extremely dense when fired at very high temperatures. As a result it absorbs almost no water and is practically frost-proof, scratch-resistant and abrasion-resistant. It is available in many looks: imitating wood, natural stone, concrete or marble, and in polished, matt or textured finishes.\n\nDuring production the raw mix is pressed, dried and fired. A distinction is made between full-body (unglazed) porcelain stoneware, where the colour runs through the entire tile, and glazed porcelain stoneware, which gets its appearance from a fired-on surface layer. It is laid in a thin-bed mortar on a stable, level substrate; clean grouting and suitable slip-resistance classes are decisive.\n\nPorcelain stoneware is needed wherever durability matters: in the kitchen, bathroom, entrance area, on terraces and balconies, or in heavily used living and commercial spaces. Thanks to its low water absorption it is particularly suited to outdoor areas and wet rooms.\n\nPay attention to the slip-resistance class (R-value) for floors and wet areas, the abrasion class for high-traffic surfaces, and the format and joint pattern. Common mistakes are an unsuitable or uneven substrate, oversized tiles laid without proper technique, and a wrongly chosen finish that becomes too slippery in the bathroom. Ask to see samples and have the suitability for your specific location confirmed.
Porcelain stoneware
Porcelain stoneware is an especially dense, hard-fired ceramic tile made from fine clays, feldspar and quartz fired at very high temperatures. It is considered the most robust type of tile and is used for floors and walls both indoors and outdoors.
Example
A family in Winterthur wants to replace the ageing carpet in their living room with low-maintenance porcelain stoneware in a wood look and continue the same surface seamlessly onto the adjoining terrace. The tradesperson checks the substrate, chooses a matt version for indoors and a slip-resistant one for outdoors, and lays large-format tiles with a narrow joint. This makes the transition from living room to terrace look seamless while staying safe underfoot even when wet.
Frequently asked
What is the difference between porcelain stoneware and regular ceramic tiles?
Porcelain stoneware is fired at higher temperatures and is therefore denser, harder and absorbs less water than conventional ceramic tiles. This makes it more robust, more frost-proof and suitable for outdoor areas and heavily used surfaces. Classic ceramic is better suited to indoor walls.
Is porcelain stoneware suitable for bathrooms and terraces?
Yes, thanks to its very low water absorption, porcelain stoneware is ideal for wet rooms and outdoor areas. The right slip resistance is important: in bathrooms, showers and on terraces you should choose a slip-resistant surface. Ask your specialist to recommend the suitable R-class for your location.
What determines the cost of porcelain stoneware?
The cost depends on factors such as the quality and format of the tile, the finish (polished, matt, textured), the area to be laid and the installation effort. The condition of the substrate, necessary preparatory work and the region also play a role. It is best to obtain several quotes from local specialists and compare material and labour separately.
