Water disappears through gaps in Serafini's "sculptural yet functional" Piano washbasin
Italian brand Serafini has created a bespoke washbasin concept for high-end interiors, made from a rhythmic row of marble slabs that cleverly conceal the drainage.
The Piano washbasin, which features on the shortlist for Dezeen Awards 2025 in the product design (bathroom) category, was first envisioned ten years ago by architect Johannes Budde during his architecture studies.
The German worked with marble specialist Serafini to refine the concept, which consists of marble pieces that are arranged linearly to form a minimalist centrepiece.
Water flows between small gaps in the marble slabs, transforming the mundane act of hand washing into a more intriguing and engaging ritual.
"Piano challenges traditional washbasin design by shifting the conventional horizontal sink to a vertical composition," the brand explained.
"The name 'Piano' refers to both the musical instrument and the Italian words for 'flat' and 'slow', reflecting the design's key inspirations."
The Piano concept is fully customisable in proportion, material and finish, allowing it to be tailored to settings ranging from luxury hotels to high-end residences, boutiques and showrooms.
Customers can choose from Serafini's extensive marble collection and each product is manufactured to their specifications in Chiampo, a city renowned for its marble craftsmanship.
Once a slab is selected, the stone is then cut into smaller sections using a monoblade, before a waterjet is used to shape the finer details.
Serafini created an initial prototype measuring 170 centimetres in length from Verde Guatemala marble with a stainless-steel base.
A smaller version was built for a private client using Rosso Lepanto marble with a matching marble base and powder-coated red metal structure.
Piano's sculptural and minimalist design is enhanced by the absence of visible drainage, which is instead integrated into the basin.
The product's modular construction allows each slab to be individually removed, providing direct access to the drainage system for cleaning and maintenance.
The format also helps to minimise waste, with precise cutting techniques reducing material use and maximising yield from each slab.
Piano's timeless form and adaptability aim to promote longevity and reduce the likelihood of replacement. If repairs are required, individual slabs can be removed and replaced without the need to exchange the entire basin.
Serafini launched the Piano concept during Milan Design Week 2024. The collection comprises a wall-mounted version and a freestanding washbasin with integrated storage.
Budde and Meike Papenfuss founded their Cologne and Milan-based studio in 2020. The practice was shortlisted for Dezeen Awards 2024 in the emerging designer of the year category.
Budde applies his architectural background to projects ranging from commercial products to experimental collectible pieces, such as a multifunctional table made from anodised aluminium.
