Listening is pure enjoyment. From the gentle rustle of leaves tickled by a breeze to a virtuoso violin concerto by Mozart – music, voices and gentle sounds give us unique moments of well-being and help us to relax. Bringing together the joy of bathing with the delights of music and sound was an obvious choice for Kaldewei. SOUND WAVE is the ultimate combination of relaxing spa and unique sound experience – above and below the water.

Spa meets sound

SOUND WAVE isn’t only a winner with spa lovers. Professionals like sound engineer Bryan Gallant from The Warehouse Studio in Vancouver, Canada, are big fans of this Kaldewei innovation. “We put in a Kaldewei sound bath tub for certain clients who decide they like a soak (a bath) after work, the great thing is, they can listen to the music they made while dropping the soap!” says the studio manager.

A sustainable steel enamel Kaldewei bathtub fitted with SOUND WAVE recently took up residence at The Warehouse Studio in Vancouver. Opened by Bryan Adams in 1997, The Warehouse Studio consists of four studios of varying sizes and fit-out, housed in an historic building in the west coast metropolis. Rock greats have been regular visitors here for years: REM, Nickelback, Billy Joel, Muse, Metallica and AC/DC have all recorded tracks or entire albums at The Warehouse Studio. Bryan Adams himself has also made most of his recordings here.

After finishing work, the musicians can now enjoy the special mix of sound and relaxation and literally immerse themselves in their new songs – like in a symphony in enamel.

How it works

Suitable for any bathroom, SOUND WAVE is the acoustic innovation that turns a steel enamel bathtub into a resonant sound box. Compatible with all Kaldewei bathtub models, this bathroom audio system is installed at the same time as the bathtub. Six acoustic panels and two transducers are attached to the outside of the bathtub; these remain entirely invisible behind the panelling. SOUND WAVE can play every kind of audio file via Bluetooth from a smartphone, laptop, tablet or PC. The chosen digital device then works as a remote control which is automatically recognised after the first sign-in. Up to eight devices and individuals – a biggish family, for example, or an entire band – can be paired with SOUND WAVE at the same time.

“Unfortunately a whole band can’t fit into the bathtub, but we’re talking with Kaldewei about designing one!” says studio manager Bryan Gallant with a twinkle in his eye.

Bryan Adams has had a close connection with Kaldewei for some time: in 2020 the Canadian rock musician and photographer was asked by Kaldewei to present the subject of hand hygiene in pictures. With “Naturally Connected” he created an emotional visual rendering of connectedness in turbulent times.
