The Opus Onyx Bathtub

ARTISAN MADE | DUTIES COVERED | FREE INTERNATIONAL SHIPPING

Exclusively designed and produced by Cultheir, The Opus Onyx Bathtub is carved from a single block of Indonesian onyx by a small group of master stone artisans. The result is a vessel of extraordinary translucence — when backlit, the onyx glows with warm amber, honey, and ivory tones that shift throughout the day.

Custom made to order, no two Opus bathtubs are alike. The natural banding and veining of each onyx block determines the final character of the piece, ensuring your bathtub is genuinely one of a kind.
