Ceramic or mineral composite washbasin: Differences and selection criteria
The choice of washbasin shapes the design and function of a wash area, with the material playing an important role alongside its shape and size. Ceramics and mineral composite castings differ in terms of their manufacturing processes, their surface finishes and the design possibilities this affords.
A blanket recommendation for either of the two materials is therefore short. Whilst ceramics are characterised by their hard, solid surface, the mineral composite casting process allows for flexible shaping, enabling functional details to be integrated directly into the washbasin, depending on the model. There are also differences in the feel. Which of these features are relevant to your selection depends on the planned wash area and the desired design.
HEWI offers washbasins made from both materials for a variety of interior designs and applications. The comparison shows how ceramic and mineral composite differ and which criteria can be taken into account during the selection process.

What makes a ceramic washbasin stand out?
Sanitaryware has a hard, non-porous surface that absorbs hardly any water, which is one of the essential reasons why this material has long been used for sanitary products. Sanitaryware also demonstrates a high degree of resistance to the various influences encountered in the bathroom. Please refer to the relevant product specifications to find out which resistance properties apply to the specific design.
Another characteristic feature is the manufacturing process, in which the ceramic is first shaped and then fired at high temperatures. This produces the characteristic ceramic surface; at the same time, the process sets a frame for the possible shapes and sizes. For a specific washbasin area, a ceramic model is therefore selected whose dimensions and design are suited to the relevant plans.
As well as its technical properties, the material’s feel also shapes how it is perceived. The solid ceramic surface gives a different impression to that of mineral composite. As this difference can only be conveyed to a limited extent through photographs, the immediate feel of the material can also play a role during the selection of a washbasin.
The HEWI DUO washbasin demonstrates how ceramic materials can be incorporated into the design of a washbasin area. The round countertop washbasin, made from high-quality ceramic, measures 42.6 cm in diameter and 15 cm in height, whilst the basin itself is 12 cm deep. Its circular shape makes the washbasin a design feature in its own right within the wash area.As a countertop washbasin, DUO can be combined with matching bathroom furniture, thus allowing for a variety of bathroom furniture designs featuring a ceramic washbasin.
The colour scheme can also be incorporated into the interior design concept. The interior is white on all models, whilst the exterior is available in glossy white and grey finishes. Alternatively, it is available in black matt.


What are the advantages of a mineral composite washbasin?
Mineral composite is moulded, which allows for flexibility in the contours and size of a washbasin; however, this malleability is not only relevant to its external design. Depending on the model, functional areas may also already be incorporated into the design of the washbasin. Storage surfaces or gripping options can, for example, be integrated directly into the design, meaning that the design and required functions can be considered together right from the conception stage of the washbasin.The casting process can also open up additional possibilities in terms of size.Models with variable lengths demonstrate how washbasins can be adapted to specific spatial requirements within the parameters intended for the respective product.
This may be particularly relevant when existing areas are to be used for specific purposes or when certain dimensions need to be taken into account in the planning process.

Another difference compared with ceramic lies in the way the surface is perceived. Mineral composite has a dense, low-porosity surface and is often perceived as warmer or pleasantly cool to the touch, meaning that the choice of material also influences the tactile experience at the washbasin.
HEWI utilises these features in a range of washbasin designs. As well as models available in various lengths, the product range includes designs with integrated grab rails, whilst in other models, storage areas are already an integral part of the washbasin’s design. The material’s malleability thus serves a specific design function, as the design of the washbasin can be tailored to the intended layout of the room and the required functions.

Compact mineral composite washbasins: Solutions for small-space designs
When space is limited, people often look first at the width and depth of a washbasin. However, when it comes to making the most of the available space, the layout of the washbasin area is also crucial, as the position of the fitting can be just as important as a designated storage area.
It is precisely here that the design possibilities offered by mineral composite can be put to practical use. HEWI is expanding its product range to include compact washbasins, with designs tailored to suit a variety of room layouts. In one model, the fitting is positioned to the side, whilst another features a side shelf integrated directly into the washbasin. A rounded, reduced design also offers a further way of adapting the washbasin’s contours to a limited space.
For small washbasin units, ‘compact’ does not therefore refer solely to small external dimensions, as the layout of the features within the available space is just as important. When planning, it is therefore worth considering the specific design rather than just the width and depth of the model.

What criteria are important when choosing between a ceramic or mineral composite washbasin?
The decision on which material to choose – a ceramic or mineral composite washbasin – is best made in light of the specific requirements of the washbasin area in question. If an existing ceramic mould is to be integrated into the design concept, the available models and their sizes form the basis for the selection. If, on the other hand, specific contours or functions already integrated into the washbasin are required, the design options offered by mineral composite may be worth considering.
The desired feel of the material may also influence the decision, as ceramics and mineral composite differ in terms of their texture, even though their surfaces may look very similar. It is even this difference that can easily be overlooked when making a selection based purely on visual criteria.
However, the intended use alone does not determine the material, as ceramic and mineral composite washbasins can be used in different types of sanitary rooms. In a private bathroom, the layout of the room or your design preferences may influence your selection. In the case of washbasin areas used in public or institutional settings, specific functional requirements may take on greater importance, although the suitability of the particular washbasin design for its intended use remains crucial.
The key question, therefore, is not which material is fundamentally better, but which of its properties are actually utilised in the specific washbasin and whether the particular design is suitable for the planned wash area.
What should you bear in mind when caring for ceramics and mineral composite castings?
Care requirements depend on the material and the specific surface. As specific surface finishes may vary, general care recommendations cannot be applied to every washbasin without further consideration.
For ceramic and mineral composite washbasins, the care tips for the specific product are therefore decisive, as they take into account the specific material and surface finish and should be followed to ensure the long-term preservation of the product.
Select ceramic and mineral composite finishes to match your washbasin area
Washbasins made from ceramic and mineral composite offer different material properties and design options. The specific washing area is therefore the key factor in the selection: Which design is best suited to the layout of the space and fulfils the intended functions? The HEWI product range offers washbasins made from both materials, which can be integrated into a variety of interior design schemes.
An essential difference lies in the manufacturing process: Ceramics are shaped and then fired, whereas mineral composite castings are cast. This opens up a range of design possibilities; furthermore, the materials differ in terms of their texture.
The casting process used in mineral composite allows for a variety of contours and can facilitate the integration of functional details, such as grip options, into the washbasin mould. With ceramic products, on the other hand, the selection is made from the available ceramic shapes and sizes.
Yes. Both materials are suitable for different types of sanitary room, although the specific design of the washbasin and its suitability for the intended use are the decisive factors
The appropriate care routine depends on the specific surface and product design, which is why the care tips for the specific washbasin are decisive.
