Floor-to-Ceiling Tall Cabinets Without Ceiling Trim – Seamless Integration for Your Kitchen
Space Marvel
Utilise elegant heights and design spaces with refined purpose — creating a harmonious and sophisticated atmosphere throughout.



Elegance in Height
A seamless floor-to-ceiling tall cabinet run is achievable without the need for a ceiling trim, as the fronts extend above the carcass in height. Structural elements, such as ventilation ducts, can be elegantly concealed in this way.
Technical details about our upward door extension
Everything you need to know about upward Türverlängerung in kitchen planning, all in one place.
How can a full-height tall cabinet row be achieved without a ceiling panel?
A full-height tall cabinet run can be achieved through the use of Frontverlängerung above the carcass.
What are the advantages of the LEICHT solution?
- Continuous vertical joint pattern with no visible separation line
- Seamless concealment of structural elements such as ventilation ducts
- Precise adaptation to varying ceiling and room heights
- Compatible with optional storage extension for enhanced functionality
What aesthetic advantage does an upward Frontverlängerung offer?
The gap between wall cabinets and the ceiling is traditionally concealed by a horizontal ceiling panel running the full width of the kitchen. By introducing a Türverlängerung, this horizontal element is removed entirely — allowing the vertical lines of the cabinetry to flow seamlessly upward, creating a clean, uninterrupted transition to the ceiling.
How far can the door extend above the cabinet?
We recommend an overhang of no more than 13.25 cm, which also allows for the effective concealment of ventilation ducts from range hoods.
Is the gap between the wall cabinet and the ceiling, for example, just 10 cm?
To maximise storage capacity, a combination of cabinet height adjustment and Frontverlängerung is recommended.
