The knob reminds the elegance of a water droplet due to the volume curvature and transparent material.
The body shell surface, mirroring the gentle ripples of a droplet, complements the knob’s motif.
Thanks to the recessed geometry, the interface design provides more space for the hand rotating the knob.

A drop of water

Elevating the water-heating experience beyond utility, the design embraces everyday comfort in a pure, minimal form,
balancing geometric clarity with an intuitive interface, reflecting a lifestyle where technology serves quietly in the background.
