Zefiro · The collection

Water held
in pure form.

Sculptural volumes with a quiet presence, designed to turn bathing into a spatial experience.

Transparent colour reveals depth and reflection. Mineral white brings softness and visual calm. Across the collection, each freestanding form is conceived to be viewed from every angle.

01 — Freestanding basins

A vertical
gesture.

Zefiro transforms the washbasin into an independent volume. Its 45 × 45 cm footprint and 90 cm height create a slender architectural presence for indoor and outdoor spaces.

03 — The material

Warmth,
held longer.

Seiko Hydroaluminite is a high-performance mineral composite created for strength, comfort and a refined tactile quality.

Used for the white Zefiro bathtubs, its smooth surface feels pleasant rather than cold and helps the bath retain heat. It is resistant, durable and simple to maintain in residential, hospitality and wellness settings.
