Modern brand kitchens with tradition.


For more than 50 years rational has been combining excellent design, innovative technology and outstanding functionality. Simply unmistakable, always carefully thought out and of solid lasting value, our kitchens appeal to the individual furnishing tastes and lifestyles of international target groups – from purist and design-oriented through timeless modern to stylishly elegant. Early on rational developed its own product philosophy, lending each model a distinct typically rational character and widening the scope for personal creativity and customized solutions.In terms of technology, quality and functionality we set high standards. The use of modern production technologies coupled with traditional craftsmanship and the choice selection of materials are part of the corporate concept. The award of the “Golden M”, the prestigious certification mark of the Deutsche  ütegemeinschaft Möbel e.V. (German Quality Assurance Association) underlines this claim.

The outstanding quality standard has made rational a sought-after brand not only at home but also abroad. In international business circles, rational is held in high esteem for its expertise in handling large-scale projects. Today rational is  represented in more than 50 countries across the globe. On numerous occasions exceptional projects, such as parts of the luxury villas of “The Palm Jumeirah” in Dubai and the apartments of “The Pearl” in Qatar, have been equipped with Rational kitchens.

Carcase and removable shelves 19 mm thick
rational_removable_shelvesThe rational carcase and removable shelves are made of
19 mm thick 3-layer quality particle board (E1) with a direct
coating of high-quality velvet-white laminate on both sides.
This guarantees a long service life and a high degree of
stability – particularly in the case of pull-outs. In addition, the
carcase front edges are provided with a protective thick edge.
Fronts 22 mm thick
fronts_22mm_thickAlmost all the fronts have a material thickness of 22 mm.
As such the company provides customers with real added
value in terms of the quality and combination variety of
the various product lines.
Extremely sturdy hinges
rational_kitchens_sturdy_hingesIn everyday use hinges and fittings are subjected to
a great deal of stress. That’s why rational uses
exclusively brand products from Blum which have passed all
the simulated stress tests performed in the test lab.
This involves testing the service life of a hinge by
subjecting it to as many as 200,000 door movements.
Optimum hanging system
rational_kitchens_hanging_systemAll wall-mounted units and shelving are supplied with high-
quality sturdy steel hanging systems.The easy adjustment
function is particularly installation-friendly.


5-year guarantee
In order to illustrate our high quality standard, we voluntarily extend to our contracting parties a 5-year guarantee covering free-of-charge replacements with regard to the product’s functionality and quality of workmanship for any proven cases of manufacturing or material defects.
Soft and high-gloss lacquer

The soft lacquer produced at rational is a water-based
paint that is free from solvents and therefore extremely
eco-friendly.A special process gives the soft lacquers
an even, soft-textured surface.Thanks to UV technology
the soft lacquer is extremely light fast andeasy to clean.
Its excellent chemical resistance is confirmed by the
product-testing institute, LGA QualiTest GmbH.

Rational_kitchens_atmosAt Rational these materials are used for decorative surfaces,
such as fronts, carcase and worktops,
which are exposed to extreme wear and tear.
rational_unitsSuper-matt lacquer with its saturated colour and calming
effect, boasting a unique level of sheen close to zero,
impresses on account of the subtle softness of both its look
and feel. No reflections are produced, allowing theeye to
focus fully on the furniture’s shapes and forms. What’s more,
the surface, lacquer finished in a patented process, offers
a high degree of resistance, thereby affording matt
surfaces exceptional durability.
Safety glass
Rational_glass_kitchenThe types of glass used are subjected to special glass breakage
tests according to DIN/EN 1153 (safety requirements and test
methods for built-in and free-standing kitchen units).
Most of the glass used by rational is safety glass.
Rational_kitchens_sheffieldVeneered means that a thin layer composed of individual
strips of fine quality wood is glued and pressed to the
surface of a high-quality substrate. Book-matched veneers
look particularly classy. In this process the veneer for
a kitchen is selected from one single tree trunk and put
together specifically for the fronts of that particular
kitchen. This ensures that there is a harmonious and
uninterrupted matching of the grain pattern across all
the fronts. Thus every kitchen produced in this way has
its own unique appearance.


“Golden M“
rational is one of the first kitchen manufacturers to have been awarded the “Golden M”, quite possibly Europe’s most important quality mark. The Deutsche Gütegemeinschaft Möbel e.V.“ (German Quality Assurance Association) only awards the “Golden M” to furniture which has passed extensive and stringent testing. The furniture must be sturdy, safe, durable and well made and may not contain any substances that could pose a health threat. This gives the kitchen consumer the assurance that the furniture being purchased is of the best possible quality and has been reliably tested and approved as being non-harmful to health.
planningTo ensure that working in the kitchen doesn’t become a
back-breaking experience, rational offers its units, plinths
and worktops in a choice of different heights to meet individual
requirements. The key factor to choosing the ergonomically
correct working height is the height of the elbows when bent.
The AMK (Work Group “Modern Kitchen”) recommends that the
distance between the worktop and the elbows when bent
should be 15 cm.
Planning variety
planning_qualityIndividuality is the key! With a broad range of product lines,
