By embarking on a design development process for its Miranit countertop washbasins, FRANKE had a clear goal in mind: to design attractive products for public and semi-public sanitary settings, with target groups in the fields of architecture and planning. The challenge lay in translating the design vocabulary of existing washbasin fittings, also developed by CULTURE FORM in a previous project, to another product type. The results speak for themselves. Crowned German Design Award winners, the QUADROtop and RONDAtop are the result of our productive, longstanding collaboration with FRANKE. This project also gave CULTURE FORM the opportunity to demonstrate its special strengths. Besides the product design, the agency also drew up the communication concept for the brochures to introduce the new FRANKE products, along with a 360° visualisation on the FRANKE website.


As winners of the German Design Award, the countertop washbasins are the stars of the FRANKE product range.

Translate existing design vocabulary to a new product family.

Innovative design in harmony with the brand identity.

The design of the Miranit countertop washbasins clearly follows the FRANKE design vocabulary. Despite similarities to the shape of the standard fittings, translating and evolving these elements represents a considerable challenge. The delicate rim affords these washbasins a stylish, premium-quality character. In addition, the innovative sealing concept sidesteps unclean silicon joints and further enhances the washbasins’ elegance. We created two variants of these washbasins: a somewhat rectangular model (QUADROtop) and a round model (RONDAtop).

The design process: iteration and evolution



Firing the starting shot with thorough preparation

Following a joint kick-off workshop, we launched into an intensive research phase focused on the target group. This allowed us to identify aspects that formed the basis for the next stages of the design process.



Approximating the design language

In the design concept phase, we use graphic techniques to approximate difference approaches to the design language. Even at this early stage, we had to take specific material properties and manufacturing characteristics into account.



Making design elements tangible

In the next phase, design development, we created and visualised all the essential design elements for our preferred design and also created 1:1 models. Working closely with the client’s development team, we then examined the ergonomic properties and tested other aspects.



Down to the finest detail

In the final stage, we detailed the most design-intensive surfaces with apertures, shaping and surface transitions. We then produced the CAD data for different size variants in line with all known production-technical requirements.
