Noctira is a made-to-order freestanding soaking bathtub carved and hollowed from one solid block of Natural Absolute Black Granite. Its asymmetrical oval profile, gray-black lychee-textured exterior, polished black bathing interior, and two opposing chiseled rim notches create a distinctive architectural statement for luxury residences, designer bathrooms, boutique hotels, spas, resorts, and wellness projects. Custom dimensions, stone selection, finish, drain coordination, and project details may be reviewed for technical feasibility.
Noctira combines a tactile, hand-finished exterior with a smooth polished interior. The two opposing rim notches are integral to the BT-061A design and must be preserved in the approved shop drawing. The visual contrast between the lighter textured exterior and the deeper black polished bathing surface emphasizes the tub’s monolithic construction.
Absolute Black Granite is a dense natural black granite valued for its dark, relatively uniform mineral field. It is granite—not marble, travertine, limestone, quartzite, concrete, or an artificial composite. Tone, mineral distribution, fine speckling, natural markings, and how the stone responds to texture and polish vary by block.
The gallery uses new styled and studio visualizations generated from the supplied BT-061A shape and material references, a verified public dimension graphic, and selected shared granite fabrication and packing references. The supplier-style white-background images are not used as final gallery media. Styled scenes communicate design direction and do not represent a completed client installation. Process and packing photographs illustrate general granite-bathtub methods and do not document this exact Noctira order.
Final dimensions, tolerances, interior profile, rim-notch geometry, drain and overflow interface, empty and filled operating weights, structural loads, plumbing clearances, and installation requirements are subject to the approved project shop drawing and verified factory documentation.
Available-block photographs can be reviewed before fabrication. Approval should consider black tone, mineral uniformity, fine markings, exterior texture, and how the chosen block will appear when the rim and interior are polished. Natural variation is inherent to a one-piece stone bathtub.
Fabrication begins after the required project details and shop drawing are approved. The drawing confirms final exterior and interior dimensions, asymmetrical profile, notch geometry, base, drain and overflow positions, hole diameters, plumbing interface, finish, tolerances, and custom requirements. Reference images and published dimensions must not replace the approved drawing for site planning.
Custom dimensions, block selection, exterior texture, interior polish, drain coordination, overflow configuration, and project-specific details may be reviewed for feasibility. Changes can affect proportions, stone availability, structural integrity, weight, plumbing, access, production method, schedule, and price.
The verified drawing shows a centered drain. A licensed plumbing professional must review the final drain location, diameter, fitting interface, overflow requirements, waterproofing, rough-in, service access, and local code before fabrication and installation. Drain fittings, overflow hardware, and faucet equipment are not assumed to be included unless stated in the written quotation.
A qualified project team must confirm floor loading, support, the verified empty and filled operating weights, doorway and corridor clearances, stairs, elevator capacity, receiving route, lifting equipment, waterproofing, plumbing, and final placement. Professional heavy-stone 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 using protective materials and a reinforced export crate. The written quotation controls packing, freight, customs, import-duty, remote-area, and destination service terms. Inspect and photograph the crate before signing where possible, note visible damage on the carrier receipt, preserve all packaging, and follow the written claims procedure promptly.
Clean the polished interior and textured exterior with a soft cloth, non-abrasive sponge, or soft brush and a pH-neutral natural-stone cleaner. Avoid acidic products, bleach, harsh descalers, abrasive powders, and abrasive pads. Rinse away oils, salts, dyes, cosmetics, and residue promptly. Sealing and maintenance recommendations are project-specific and depend on the approved stone block, finish, water chemistry, and installation environment.
OIXDESIGN supports residential and contract projects with stone review, finish coordination, shop-drawing submittals, dimensional and plumbing coordination, quantity planning, production scheduling, export crating, and destination logistics. Include 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 and overflow fittings, 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.
