New sliding door for natura 4000
Discover our versatile series for bathtub solutions, continuously enhanced with the latest innovations. Pivot, bi-folding and sliding doors come together in a range designed to combine comfort, functionality and refined aesthetics. Proven technologies from other series ensure lasting quality and reliability. The new sliding door adds a distinctive touch to the collection. Refined details such as the curved shell handle, the support bar and the softly rounded corner underline the seductive design and elegant character of this solution.
Our bathtub solutions are designed to enhance every bathroom in the best possible way, even when installing a shower enclosure is not possible or when the bathtub is to be retained. They offer the same quality, comfort and elegant design that distinguish our shower enclosures. The latest innovations concern the natura 4000 and multi-S 4000 series: two solutions characterized by extensive customization options and a high degree of architectural flexibility.
Solution for bathtubs from the natura 4000 series
The sliding door for bathtubs from natura 4000 was introduced this spring to allow even those without a shower enclosure to benefit from the beauty and functionality of this series. Its details emphasize the seductive design of the solution and make it the ideal choice for anyone seeking high functionality without compromising on aesthetic quality. The series is available in a wide range of profile finishes, which can be freely combined with numerous glass finishes. Discover, for example, the new Bronze glass, characterised by its warm and intense colour, which creates a cosy and relaxing atmosphere in the bathroom. The visual effect is even more striking when combined with Pearl colours or the stainless steel look finish, giving the bathroom a refined and modern aesthetic.
Further highlights make it highly functional and easy to use:
- Equipped with the discreet ACS – Automatic Close & Stop system, the sliding door glides smoothly and precisely into position with just a gentle touch. During the final centimetres, the door automatically slows and aligns into its open or closed position, ensuring both ease and comfort in everyday use.
- The shell handle is mounted on a slim aluminium profile — an elegant and practical choice that enhances grip and makes cleaning easier.
- The upper horizontal profile and support bar blend harmoniously with the elegantly cut rounded upper corner, underlining the seductive character of the model.
- A discreet connection joins the support bar to the wall, further enhancing the transparency of the glass and the visual lightness of the solution

Solution for bathtubs from the multi-S 4000 series
The multi-S 4000 range is one of the most versatile and multifunctional solutions of Duka. Suitable for a wide variety of planning situations and any bathroom environment, it meets a broad range of requirements and offers effective solutions for renovations and for new builds. Thanks to its flexibility, it fits naturally into residential, contract and hospitality settings. The recent design restyling highlights greater aesthetic purity, defined by a more delicate formal minimalism, visible also in the details, and by even more advanced functionality. The particularly versatile character of the pivot doors and bi-folding doors of multi-S 4000 bathtubs is further enhanced by their simple and quick installation, easy cleaning and high product durability over time.
- The multi-S 4000 hinges allow a 180° outward opening and stand out for their fluid shape, in harmony with the soft lines of the model. They are bonded to the glass with UV Brillant bonding. This bonding technology from Duka lets the new shapes of the elements and the luster of the material show through and allows the glass to fully display its transparency.
- The cylindrical tubular hinge has been reduced to a minimum, allowing the transparency of the glass to take centre stage. Minimalistic in appearance, great in functionality: the proven „auto close“ closing system allows the pivot elements to engage exactly where required.
- The profile of the pivot solutions with fixed element and bi-folding door has also been reduced, while maintaining its technical function: the 20–25 mm wall adjustment on the side and fixed panels is guaranteed by the continuously adjustable tempered glass inside the wall profile.
- The pivot solution without fixed element can be easily adjusted by means of a telescopic screw within the specified adjustment range.
