Thirteen stones carry the collection. Each behaves differently under water, light and time — this is what to expect from yours, and how little it asks of you.
Sedimentary · warm
Honey Travertine
Laid down in layers by mineral springs, warm to the touch before the bath is ever filled. Pores filled and sealed at the workshop; hones to a soft matte skin. The Monolith
Translucent · in the body
Honey Onyx
The one stone here that genuinely passes light. Lit from behind, the body of the vessel glows amber — but the rim is carved heavier for strength and reads as a dark band above it. The light lives in the walls, not the edge. Calcite: softer than marble, unhappy with acid. Candela
Crystalline · opaque
Green Marble
Deep green marble veined like light through leaves. It was offered in green onyx until the workshops told us blocks that large are not currently quarried — so it is marble, it is opaque, and it will not glow. To our eye it is the more serene of the two. Verde
Onyx · surface light
White Onyx
Bone-white and close-grained. Where honey onyx passes light, white onyx holds it on the surface — this is a piece for stillness rather than spectacle. If you want a vessel that glows, choose Candela instead. Alba
Riverbed · monumental
Black River Stone
A boulder lifted whole — outer face exactly as the water made it, the bathing bowl hollowed and finished smooth. At 900 kg it is specified with the floor, not placed on it. Erebus
Crystalline · blush
Rosa Marble
Blush veins through warm marble, polished to a soft sheen that takes the colour of every sunrise it faces. Calcite — keep acids out of the room. Rosa
Crystalline · architectural
White Calacatta Marble
Bright white threaded with grey and gold, carved into the broadest sweeping bowl of the marbles. Genuinely rare Italian stone — and a great deal of what is sold as Calacatta is not. Polished it holds a mirror; honed it holds a hush. Calacatta
Crystalline · dramatic
Black Marquina Marble
Deep black threaded with lightning-white veins, honed to a still matte that reads almost like ink — architecture you bathe in. Nero
Crystalline · velvet green
Jade Green Marble
Reads as a solid, velvet green — denser and quieter than banded onyx — with a sheen that deepens with the light around it. Imperial
Sedimentary · porous
Golden Sandstone
Soft banding the colour of late afternoon. The most porous stone in the collection — it most rewards the 12–18 month re-sealing rhythm. Dune
Igneous · hardest
Black Granite
Charcoal flecked with silver mica — effectively immune to scratching in domestic life, the least demanding stone to keep, and the heaviest piece we make. Atlas
Volcanic · even
Black Basalt
No veining at all — a deep matte charcoal that holds the heat of a bath long after the water stills. Some rooms need an object that stops asking for attention. Vulcan
Sedimentary · quiet
Cream Limestone
No veining, no pattern — a soft, chalky uniformity that turns the vessel into pure form. Porous like sandstone; same re-sealing rhythm. Aura
On thickness, and why these are heavier than you might expect
A carved vessel is never a uniform shell. It is thinnest in the body and thickens toward the rim and base, because that is what survives carving, an ocean crossing and daily use. Where a workshop has confirmed the wall it would build, we publish that figure; where it is still our estimate, we say so. Every number, in metric and imperial, is on the specifications page.
The practical consequence: filled and occupied, these vessels weigh between roughly 980 kg and 1,425 kg (2,160–3,140 lb) over a small footprint. On a ground-floor slab that is rarely a question. On a timber upper floor it usually needs checking. Have your architect or structural engineer confirm the floor before you order.
Care
Every vessel is sealed before despatch. After that, the routine is deliberately small:
- CleanpH-neutral soap and warm water. Nothing acidic, nothing abrasive — no vinegar, no citrus, no scouring cream. A soft cloth is enough.
- Re-sealEvery 12 to 18 months in use. Sandstone and limestone keep to the shorter end; granite and basalt barely notice. Any competent stone restorer can do it in an hour, and we will point you to one in your region.
- Standing waterDrain after use rather than leaving the vessel filled for days. Stone is happiest in the rhythm of use it was carved for.
- ChipsSmall edge chips in natural stone are repairable in place. Write to us before anyone drills, grinds or “polishes out” anything.
Natural fissures, colour movement and vein lines are characteristics of the material rather than faults; no two blocks are alike, and the piece that reaches you will not be identical to the one photographed. That is the point.
