roca turns to altherr désile park for updating its meridian collection

INTERVIEW WITH JANNETTE ALTHERR OF STUDIO ALTHERR DÉSILE PARK

Spanish bathroom brand, Roca, turned to the Barcelona-based studio Altherr Désile Park (ADP) for a contemporary update of its Meridian collection, seeking a studio that could demonstrate a sensitivity to an existing design, be respectful of its legacy, yet capable of bringing a new, fresh perspective. The updated Meridian collection successfully merges these requirements, offering a system of basins, furniture, and WCs characterized by fine materials and soft geometry. In this exclusive interview with designboom, designer Jannette Altherr shares insights into how the studio approached the sensitive task of evolving a classic bathroom design for the modern age, transforming its functional pieces with an architectonic quality.

‘We believe that everything is related – the user and their emotions, cultural context, the build and the natural environment, the materials, colors, production and resources. Every element is a matter of context. Meridian already has a powerful name that represents one of its important aspects: the arch as a symbol of Mediterranean architectural culture. This was crucial to preserve,’ begins Jannette Altherr.

ROCA’S MERIDIAN CULTIVATES A SENSITIVE, ARCHITECTURAL APPROACH

Altherr Désile Park’s sensitivity to context was vital when approaching Roca’s Meridian line. The original collection’s crucial DNA was the arch, a powerful symbol of Mediterranean architectural culture. ADP translated this spirit by drawing inspiration from the austere, vernacular expressions found in the Spanish, Portuguese, or Greek countryside. This design choice reflects a commitment to reduced, elemental shapes, the interplay of strong light and shadow, and the use of noble materials like ceramic, wood, and metal. While ADP also works in the luxury sector, this project offered a unique opportunity to translate the quality, care, and attention typical of luxury design into products that are accessible to a broader audience — a core value shared with the Spanish brand. Rejecting the idea of constant invention, their approach favors an evolution that is subtle and deeply sensed.

‘There is this hype around the idea of breaking things and starting completely anew. I think that is, to a large degree, a myth. Sometimes it’s more important to keep, to care, and to delicately evolve things instead of throwing away and starting again,’ explains Altherr. ‘We spent hours defining a concept together with Roca, and “timeless balance” really captures the essence of the collection. When I think about timelessness, it relates to what we call collective memory. We preferred designing something that doesn’t seek to provoke or be aggressive. We looked for the opposite: something that makes you feel at ease and adds quality to your space. Something that speaks to all the senses including sound and touch — the subtle elements that create atmosphere, rather than just what is captured in a photograph.’

CONTEMPORARY UPDATES FOR A LIGHTWEIGHT AND DELICATE COLLECTION

ADP studio’s update focused on refining and lightening the Meridian collection. The original washbasin felt too heavy in its appearance to fit the modern aesthetic of bathroom design. The solution was to utilize Roca’s Fineceramic® material, which permitted the use of super thin and delicate dimensions that were previously unachievable. This aesthetic reduction was paired with an increased function, adding a subtle frame and a dry zone. The soft, curving shape of the basin was inspired by the cultural importance of water, specifically referencing a drop falling onto a water surface, creating a gentle ripple.

‘If you have a small room and use thick, solid furniture, it can look out of proportion. To create something that feels refined and carefully done in a small dimension requires delicate detail. We had to translate the original pieces into a design way more contemporary and easy to use in real life. This meant adding storage, using the ceramic in a more up-to-date way, and utilizing Roca’s capacity with fine ceramic to do something more lightweight and delicate instead of a thick block. The pieces needed to become more practical, but also more refined and a bit more luxurious,’ states the designer.

To create a richer ambiance, the material selection went beyond pure hygiene to enhance a sensuous quality. The furniture units use FSC-certified wood with a textured surface, and the metal elements feature a slightly rough lacquer finish that resembles cast metal. The color palette — white, black, and gold — is inspired by the Spanish light, which is characterized by strong white light and deep black shadows, balanced by the golden light of the early morning.

‘We wanted to think about materials as something that enhances a rich perception, rather than being driven only by hygiene. The aim was to create a “nice to touch” sensation. The surface of the wood is always textured and not finished with a lacquer. The metal is a bit rough, like cast metal. It has little pigments on the surface that break the light in a more complex way than a flat lacquer. This avoids the feeling of industrial dryness and adds more complexity to the surface,’ she shares.

A key technical and aesthetic victory was the redesign of the often-neglected backpack toilet where the water tank is sitting behind the toilet. While the in-wall flush is often preferred in high-quality projects, the backpack version is essential for older buildings lacking space to construct a double wall, or for hospitality and public settings requiring quick, inexpensive repairs. ADP worked with Roca’s expertise to achieve a much straighter, more architectural language for this highly needed version, shifting the object’s perception from a bowl saddled with a backpack to a column that supports the bowl. This change brings a sense of solidity, fulfilling the studio’s ethos of providing quality design to a broad audience. Furthermore, the toilets utilize innovative flushing technologies such as the Rimless® Vortex System and dual-flushing systems to improve hygiene and optimize water consumption.

‘We realized there is a real need for this backpack version. With Roca’s excellent development team and expertise, we managed to create a much straighter shape. We wanted to relax the gesture and make a connection to the architecture. Instead of the bowl carrying the water container, the water tank serves as a column supporting the bowl,’ adds Altherr to describe the design details that bring character to the collection.

The Meridian collection has already received important recognition, including a Red Dot Award in 2025. Functioning as an ‘alphabet of simple elements’ in multiple sizes, it allows for a wide range of configurations across diverse project needs. The system includes several washbasin options, from compact wall-hung versions to models designed to pair with furniture. These are complemented by two furniture lines: a wall-mounted wood container and a floor-standing metal structure that combines with wood drawers. By providing these flexible components, Altherr Désile Park has created a robust system that adapts easily to diverse spatial, aesthetic, and functional requirements, ensuring the collection can continue to evolve with the user and remain part of the home for many years.
