Cavira is a made-to-order freestanding soaking bathtub carved and hollowed from one solid block of Natural Gray Charcoal Mist Granite. Its long, low organic oval, subtly irregular hand-shaped rim, textured gray exterior, and deep polished charcoal-gray interior create an architectural focal point for luxury residences, designer bathrooms, boutique hotels, resorts, spas, and wellness projects. Custom dimensions, stone selection, finish, drain coordination, and project details may be reviewed for technical feasibility.
Cavira is distinguished from a conventional symmetrical oval by its gently irregular outer rim and varied rim widths. The monolithic exterior is softly rounded toward the base, while the polished inner basin forms a deep, smooth soaking space. The offset drain and overflow slot shown in the supplied references must be coordinated with the project plumbing plan.
Charcoal Mist Granite is a dense natural gray granite known for its fine granular structure and charcoal-to-medium-gray mineral field. It is granite—not marble, travertine, limestone, or concrete. In Cavira, the rougher exterior emphasizes the stone’s tactile character while the polished rim and interior appear darker and smoother. Natural blocks vary in tone, grain, mineral concentration, markings, and visual direction; a made-to-order bathtub will not exactly duplicate a visualization or reference piece.
The gallery uses newly created styled and studio visualizations anchored to the supplied BT-017A real-product references, an OIXDESIGN technical dimension graphic, and selected fabrication, lifting, and packaging reference photographs. The original supplier-style product photographs are retained only as internal shape and material references and are not used as final gallery media. Styled scenes communicate design direction and do not represent a completed client installation. Process images illustrate granite bathtub fabrication or packing methods and should not be interpreted as documenting this exact Cavira order.
Final fabrication tolerances, empty and filled operating weights, water capacity, exterior and interior dimensions, drain and overflow configuration, plumbing interface, clearances, and installation requirements must be confirmed through verified factory documentation and the approved project shop drawing.
Available Charcoal Mist Granite block photographs can be reviewed before fabrication. Stone approval should consider the overall gray tone, grain, mineral distribution, markings, and how the chosen block relates to the sculpted rim, exterior wall, and polished interior. Natural variation is an inherent part of a one-piece stone bathtub.
Fabrication begins after the required project information and shop drawing are approved. The approved drawing confirms the final exterior and interior dimensions, organic rim profile, base, drain and overflow position, hole diameters, plumbing interface, finish, tolerances, and custom details. Reference images and dimensions must not replace the approved drawing for site planning.
Custom dimensions, stone block selection, exterior texture, interior polish, drain coordination, overflow configuration, and project-specific details may be reviewed for feasibility. Changes can affect block availability, proportions, structural integrity, weight, plumbing, access, production method, schedule, and price.
The revised reference drawing shows an offset drain and an overflow slot. A licensed plumbing professional must review the final drain position, diameter, fitting interface, overflow connection, waterproofing, rough-in, service access, and local-code requirements before fabrication and installation. Drain fittings and faucet hardware are not assumed to be included unless stated in the written quotation.
A qualified project team must verify floor loading, support, the confirmed empty and filled operating weights, doorways, corridors, stairs, elevator capacity, receiving route, lifting equipment, waterproofing, plumbing, and final placement. Professional heavy-object handling and installation are required. Crane service, rigging, stairs, indoor placement, unpacking, final positioning, plumbing connection, and installation are not included unless specifically quoted.
The bathtub is prepared for heavy-freight transport with protective materials and a reinforced export crate. The written quotation controls packing, freight, customs, import-duty, remote-area, and destination service terms. Inspect the crate before signing where possible, note visible damage on the carrier receipt, photograph the crate and product, preserve all packaging, and notify OIXDESIGN promptly under the written freight terms.
Clean the polished interior and textured exterior with a soft cloth, sponge, or soft brush and a pH-neutral cleaner formulated for natural stone. Avoid acidic cleaners, bleach, harsh descalers, abrasive powders, and abrasive pads. Rinse oils, salts, dyes, cosmetics, and residue promptly. A compatible sealer or maintenance plan should be evaluated for the approved 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, plumbing requirements, access details, 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.
