Natural Black Granite has fine-grained mineral movement and tonal variation; every block is unique.

Stone photographs can be reviewed before fabrication. Exact color, grain, and surface character cannot be duplicated from one natural block to another.

Use a pH-neutral stone-safe cleaner with a soft cloth or non-abrasive sponge.

Avoid acidic cleaners, harsh bleach products, abrasive powders, steel wool, and aggressive descalers.

Rinse and dry bath-product residue and standing water promptly to reduce visible mineral deposits.

Clean routinely with warm water and a pH-neutral stone-safe cleaner.

Use soft microfiber cloths or non-abrasive sponges.

Do not use vinegar, lemon, acidic bathroom cleaners, abrasive pads, or metal tools.

Rinse bath oils, salts, dyes, cosmetics, and soap residue promptly.

Dry visible standing water and mineral residue, especially on the dark polished interior.

Confirm any project-specific care or treatment after the final stone block and finish are approved.

Protected and secured in a reinforced export crate for heavy freight.

Project-specific freight quotation and delivery route review are required.

Standard freight does not include stairs, indoor placement, crane service, rigging, unpacking, final positioning, plumbing, or installation unless specifically quoted.

The receiving team must confirm truck access, unloading equipment, doorway and corridor clearances, lift path, safe storage, and site readiness.

OIXDESIGN supports designers, architects, contractors, wellness, and hospitality teams with shop drawings, stone approval, quantity planning, packing documentation, and access coordination.

Is the Rivelle carved from one solid granite block? Yes. It is carved and hollowed from one selected block of Natural Black Granite.

What is Natural Black Granite? It is a dense igneous stone with fine mineral grain and natural tonal variation. The fluted exterior may read lighter than the polished interior because the two finishes reflect light differently.

Will the color and mineral pattern vary? Yes. Every block varies in tone, grain, and surface character. Available-stone photos can be reviewed before fabrication.

What are the reference dimensions? 1730 × 910 × 500 mm, with an approximately 80 mm rim and a 1000 × 600 mm reference base.

Can the size be customized? Project-specific size and profile changes can be reviewed for feasibility before quotation and fabrication.

Can the stone be approved before production? Yes. OIXDESIGN can provide photos of available stone for project-team review.

Are shop drawings provided? A project-specific shop drawing can be prepared for approval before fabrication.

Can the drain location be coordinated? Yes, subject to engineering feasibility and final shop-drawing approval. The reference drawing shows a centered drain.

Is an overflow included? Overflow requirements must be confirmed before fabrication; do not assume one is included from the reference images.

What structural planning is required? The project team must review floor loading, support, waterproofing, service access, and the final placement route.

Does delivery include indoor placement? No, not unless specifically quoted in writing.

Are crane service or rigging included? No. Lifting, rigging, crane service, stairs, and final placement require separate site coordination unless quoted.

How is the bathtub packed? It is protected and secured in a reinforced export crate suitable for heavy freight.

How should the granite be maintained? Use pH-neutral stone-safe cleaner, soft tools, prompt rinsing, and avoid acidic or abrasive products.

Can OIXDESIGN support architects and hospitality projects? Yes. Support can include stone review, custom sizing, shop drawings, quantity planning, packing documentation, and delivery-access coordination.
