Kitchens are places to live and feel good in.We develop places of modern lifestyle.


Elegant, stylish Italian design and high-grade, precision German functionality: that is synonymous with rational.
Whether contemporary and avant-garde, urban and inspiring or modern and rustic, across the globe, our kitchens reflect people's personal way of life and living. In our kitchen models, design excellence and innovative technologies go hand in hand. And have done for over 55 years in over 50 countries.

Doing so, we always place the most exacting of demands on quality and precision in terms of workmanship and finish so that we can offer you first-class, bespoke solutions that are designed to last. Right from the early days of our company's history, we developed our very own product philosophy that gives all of our kitchen models a character that is truly unmistakable.

Based on cutting-edge production technologies and expert craftsmanship, we always endeavour to combine functionality and design excellence at the pinnacle of quality. This is confirmed by the "Golden M" quality seal awarded by the Deutsche Gütegemeinschaft Möbel, the German Furniture Quality Assurance Association, and highly acknowledged across the world.
In addition to this, we are not only proud of being a member of the German Design Council since 2018 but also of winning the German Brand Award in the category of "Excellence in Branding" for our new marketing strategy.

In the international project business, our customers and partners appreciate our experience, competence and integrity, particularly in exceptional projects, such as "The Palm Jumeirah" in Dubai or "Doha Oasis" in Qatar.

The combination of design and functionality has made rational an international brand that unites the best of two worlds: German engineering skills, practicality and work ethic combined with Italian craftsmanship and that extra pinch of elegance and style.
