The Aveline Portoro Black Marble bathtub combines a low, sculptural oval soaking form with a deep black ground and natural pale mineral movement. Its softly rounded exterior, substantial rim, and gently tapered base suit refined residential, spa, hotel, resort, and wellness interiors.
Natural marble varies in tone, veining, mineral lines, texture, and pattern placement. Each finished bathtub is one of a kind, so a new order will not be visually identical to reference imagery.
Before fabrication, OIXDESIGN coordinates the selected material, key dimensions, exterior profile, interior basin, finish, drain position, overflow requirement when applicable, and relevant project notes. Fabrication begins after the required details and shop drawing are approved.
Custom dimensions, material selection, finish, drain coordination, and project-specific detailing can be reviewed subject to material, structural, and fabrication feasibility. Floor-mounted and wall-mounted faucet layouts can be coordinated; faucet hardware, plumbing components, and installation services are not included unless specifically quoted.
Project teams may submit floor plans, plumbing information, required dimensions, finish direction, destination, access conditions, quantity, and target schedule for technical review, shop drawings, project pricing, and delivery planning.
This is an extremely heavy product. Before ordering, confirm floor loading, doorway and corridor clearances, stairs or elevator access, lifting and rigging strategy, final placement, and plumbing coordination with qualified professionals. Protective foam and reinforced export crating are used for heavy freight. Standard freight excludes indoor placement, stairs, elevators, crane service, rigging, unpacking, debris removal, and installation unless specifically quoted.
Clean with warm water, a soft cloth or non-scratch sponge, and a pH-neutral surface-safe cleaner suitable for the approved material and finish. Avoid harsh acids, concentrated bleach, abrasive powders, metal scouring pads, and impact from hard objects. Confirm sealing and periodic maintenance recommendations before use.
Production timing begins after required approvals and varies with material availability, customization, and project scope. Because each bathtub is made to order, it is not eligible for return or exchange. Inspect the crate and product promptly at delivery, document any visible transit damage, and notify OIXDESIGN and the carrier according to the delivery instructions.
OIXDESIGN Special Stone Bathtubs are carved from distinctive materials such as onyx, sandstone, limestone, riverstone, and other selected natural stones. Each block carries unique translucency, banding, veining, pores, or mineral movement.
Care, finish, sealing, lighting, and installation requirements vary by stone and are reviewed for the selected material before fabrication.
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.
