Oria is a deep circular soaking bathtub carved and hollowed from one solid block of Natural Charcoal Mist Gray Granite. Its perfectly round opening, substantial rim, rugged textured exterior, and polished charcoal interior create an immersive centerpiece for large residential bathrooms, private spas, resorts, and wellness projects.
Unlike a conventional oval bathtub, Oria is defined by its circular plan and deep bowl-shaped interior. The rough exterior and polished inner basin create a deliberate material contrast while the centered drain reinforces the radial geometry.
Charcoal Mist Granite is a dense dark-gray granite with a fine, consistent mineral structure. Bush-hammering or lychee-texturing creates a lighter tactile outer surface; polishing reveals a deeper charcoal tone inside. Every natural granite block varies in background tone, mineral concentration, granular pattern, markings, and visual direction. A made-to-order bathtub will not exactly duplicate a photographed reference.
The gallery uses newly created styled visualizations and studio visualizations anchored to the supplied product references, plus a public technical dimension graphic. The original supplier-style white-background photographs, logos, and watermarks are not used as final gallery media. Styled scenes communicate design direction and do not represent a completed client installation.
The published dimension graphic is provisional only. Final dimensions, tolerances, drain and overflow configuration, plumbing interface, structural requirements, and clearances must be replaced or confirmed through a corrected BT-046A factory drawing and the approved project shop drawing.
Available stone photographs can be reviewed before fabrication. The approved shop drawing confirms the final exterior and interior dimensions, rim, base, drain and overflow configuration, finish, plumbing interface, tolerances, and approved custom details. Reference dimensions and visualizations must not replace the approved drawing for site planning.
Custom dimensions, stone selection, exterior and interior finish, drain coordination, and project-specific detailing may be reviewed for technical feasibility. Changes can affect block selection, proportions, structure, weight, access, production method, schedule, and price.
A qualified project team must confirm floor loading, the verified empty and filled operating weights, plumbing rough-in, waterproofing, access, lifting, final placement, and professional installation. Faucet hardware, drain fittings, crane service, rigging, and installation are not assumed to be included unless listed in the written quotation.
The bathtub is prepared for heavy-freight transport with protective materials and a reinforced export crate. Doorways, corridors, stairs, elevators, loading areas, receiving equipment, and final placement must be planned in advance. Standard freight does not include indoor placement, unpacking, stairs, crane service, rigging, or installation unless specifically quoted. Freight, customs, and import-duty treatment is governed by the written quotation for the destination.
Clean with a soft cloth and a pH-neutral stone-safe cleaner; avoid acidic cleaners, bleach, harsh descalers, abrasive powders, and abrasive pads. Rinse oils, salts, dyes, cosmetics, and cleaning residue promptly. A compatible sealer or maintenance plan should be evaluated for the selected granite block, finish, water chemistry, and installation environment.
OIXDESIGN supports residential and contract projects with stone review, finish coordination, shop-drawing submittals, quantity planning, production scheduling, export crating, and destination logistics. Send floor plans, access information, plumbing requirements, project location, quantity, and target installation date with the inquiry.
Final price, verified weight, capacity, production lead time, drain-fitting inclusion, and project-specific installation requirements remain quotation-confirmation items.
Each OIXDESIGN granite bathtub is carved from one solid natural granite block. Dense stone construction and hand-finished surfaces create a permanent focal point for residences, spas, villas, resorts, and selected outdoor projects.
Granite does not require a resin coating, topical waterproof membrane, surface film, or routine sealer to function as a bathtub. Normal stone-safe cleaning is sufficient.
OIXDESIGN can coordinate stone review, custom dimensions, finish, drain position, shop drawings, access constraints, multi-unit requirements, reinforced packing, and delivery documentation.
Structural support, access, lifting, plumbing, and professional installation must be confirmed by the project team before ordering.
