Our Story
Three Centuries of Custodianship
RareBath was born from a singular obsession: to rescue the most extraordinary specimens of Earth's geological heritage from obscurity and transform them into objects of enduring beauty. We serve discerning American clients from Beverly Hills to the Hamptons, delivering pieces that transcend interior design and become personal legacies.
A Generational Legacy
For generations, our family maintained relationships with geologists, estate managers, and private collectors across three continents. These relationships give us exclusive access to specimens that never reach the open market — fossils of such rarity that each represents a once-in-a-civilization opportunity for the American collector.
The Artisan Tradition
Each bathtub represents months of meticulous handwork by master artisans trained not merely in carving, but in the deep understanding of each specimen's geological narrative. They do not impose a design upon the material — they reveal what has been latent for 300 million years.

Questions & Answers
Everything You Need to Know
Petrified wood is ancient organic wood that has been replaced, molecule by molecule, by minerals — most commonly silica — over millions of years through a process called permineralization. The result is a material with the external appearance and grain of wood, but the density and durability of stone.
Our specimens range from approximately 150 million to 300+ million years old, sourced from geological formations across multiple continents. Each piece is independently dated by geological laboratory analysis, and the results are included in the certificate of authenticity.
Yes. Once fully polished and sealed, petrified wood is non-porous and completely safe for bathing. Our artisans apply food-grade, hypoallergenic sealants that protect the surface and make it easy to maintain. Every piece undergoes structural integrity testing before delivery.
Care is simple. Use pH-neutral cleansers, avoid abrasive scrubbing materials, and apply our proprietary mineral sealant annually — available exclusively to RareBath clients. Full care documentation is included with every piece.
Due to the singular nature of each specimen, pricing in USD varies considerably. Our collection ranges from investment pieces beginning in the mid-five figures to exceptionally rare specimens that have sold well into six figures. We share pricing privately during your consultation call.
All transactions are processed through a professional third-party USD escrow service. Your funds are held securely and only released upon your written confirmation of receipt and satisfaction — providing American buyers with complete protection at every step.
Yes. We deliver and install across all 50 US states. Every piece is custom-crated by specialist art handlers, fully insured during transit, and installed by our white-glove team. We regularly serve clients in California, New York, Florida, Texas, Illinois, and beyond.
