Our sourcing team works with trusted excavation crews deep in the forests and riverbeds of Central Java, where petrified wood deposits have been forming for over 200 million years. Locating a piece of the right scale, density, and colour is itself a months-long process — most are rejected before they ever reach our workshop.

Process - Custom Order

Every bathtub begins millions of years before we touch it.

Ancient trees were buried beneath volcanic ash across the forests of Java, Indonesia. Over millions of years, silica from groundwater replaced every cell — wood became stone, preserving the grain, rings, and texture of the original tree with extraordinary precision.

Our process is not manufacturing. It is uncovering — excavating a singular object, reading its structure, and shaping it into something that can be lived with.

Once at the workshop, the log is assessed from all angles before the first cut is made — an irreversible decision that defines the entire shape. Diamond-tipped blades and heavy angle grinders begin removing mass, while chisels and hand tools reveal the interior basin. This stage is where the bathtub's form is born.

Before any piece leaves our workshop, it is filled completely with water and held for a minimum of 72 hours. We inspect every millimetre of the exterior for seepage, micro-cracking, or drain seal failure. Only bathtubs that pass this test without a single drop of leakage are approved for shipping. No exceptions.

The final shaping is the most time-intensive stage — weeks of progressive grinding, from coarse diamond pads down to ultra-fine grits that bring the surface to a mirror polish. At this stage, the true character of the stone reveals itself: the grain, the fossil wood rings, the amber and black mineral gradients that have been locked inside for millions of years.

A petrified wood bathtub can weigh between 800 and 2,500 lbs. Getting it safely from a workshop in Java to a bathroom in New York, Los Angeles, or Miami requires engineering as precise as the carving itself. We work with specialist art-freight carriers experienced in handling irreplaceable stone objects.

Each bathtub is crated in a custom-built hardwood frame, padded with industrial foam on all six faces, and strapped internally to prevent any movement during ocean and road transit.
