Spanish firm Studio Inma Bermúdez has created Nu, a collection of taps designed to reference vibrant Mediterranean colours and featuring a hidden detail.

The Nu collection taps have a playful feel that is evident when the taps are turned on.

"The red and blue dots that indicate cold and hot are discreetly placed under the handles so that when the tap is turned on, the design creates a smiling face, a bit like that of a little English Guardsman with a top hat and raised sword," the studio said.

The faucets, which were designed for Spanish brand Roca, are made from brass, which the studio says is known for its longevity and durability, while the handles are made from lightweight Zamak.

The taps are finished with Cr3, a trivalent chromium compound that Studio Inma Bermúdez says is resistant to corrosion and ensures the taps last longer.

"Using Cr3 in finishes helps minimise the release of harmful substances during the manufacturing process, reducing pollution and environmental impact," Studio Inma Bermúdez said.

The collection comes in six colours – green, blue, yellow, black, white and chrome – that were "inspired by Roca's Mediterranean DNA," according to the studio.

It has been shortlisted for a 2023 Dezeen Award in the product design (bathrooms and kitchens) category.

Nu takes its name from the French word for 'nude' and Studio Inma Bermúdez sought to design a minimalist collection, "eliminating unnecessary elements and retaining only what they deemed essential".

"From the outset of the project, consideration for people and the planet played a central role," said Studio Inma Bermúdez. "Nu is manufactured in Europe to avoid unnecessary transportation."

"The design is slim, with a diameter of 35 millimetres, to minimize weight and material usage," continued the designers.

The taps feature Cold Start technology, which means that when the tap is turned on, the water is cold by default.

Users can turn the handle to the left to introduce hot water, which results in saving energy on household bills as the boiler's engagement is limited.

Nu also features flow limiters, including a fine mesh that captures and blocks particles. According to the studio, this ensures clean water and extends the faucet's lifespan by preventing blockages or damage.
