Product Introduction
Quick Summary
100% Natural White Onyx Integrated Washbasin – Translucent Freestanding Onyx Vanity Sink with Gold Metal StandKA UNITED custom white onyx integrated washbasin is milled from 100% genuine solid natural White Onyx, a premium translucent semi-precious stone selected for ultra-luxury bathroom decoration. The stone displays a milky white translucent background with natural wavy golden-amber and light coral banded mineral veins, forming warm flowing patterns that cannot be replicated by artificial stone. The whole vanity top and inner sink cavity are integrated from one thick onyx block without splicing joints, helping maintain continuous veining across the visible surfaces. Every interior and exterior face is mirror polished to enhance the stone's translucent luminous texture, while concealed LED backlight modules can be added to create a soft glowing effect through the light-permeable onyx body.

Integrated and Wall-Mounted Basin ConceptsIntegrated Onyx Sinks can be developed for freestanding vanity units, gold-frame basin structures, and project comparisons with Wall Hung Onyx Stone Basins. |
Single-Block Basin Fabrication and Gold Metal Stand StructureWhite Onyx Marble Sinks from KA UNITED are fabricated through block selection, rough shaping, cavity milling, edge profiling, internal polishing, exterior polishing, faucet-hole drilling, and waterproof sealing. Because each basin is made from natural onyx, raw block clarity and vein distribution must be reviewed before production. The brushed golden stainless steel frame uses a hollow grid storage rack structure to combine structural support, visual lightness, and practical bathroom storage. For projects comparing a Wall Hanging Onyx Marble Vanity Basin with freestanding onyx units, KA UNITED can review installation drawings, support method, sink weight, wall condition, and plumbing layout before quotation. This image position is suitable for a fabrication photo showing raw onyx block selection, basin cavity milling, polishing, faucet-hole drilling, golden frame assembly, or workshop inspection. |

This basin works well with brushed gold fittings, warm indirect lighting, travertine walls, beige marble floors, microcement finishes, dark wood cabinetry, and luxury hotel bathroom palettes. Before installation, the project team should confirm water supply, drainage, LED access, waterproof protection, support frame position, and site maintenance requirements.

Care and Maintenance for White Onyx Integrated Vanity Washbasins
White onyx vanity sinks should be cleaned with a soft cloth, clean water, and pH-neutral stone-safe cleaner. Avoid acidic bathroom cleaners, vinegar, lemon products, abrasive powders, rough pads, strong solvents, bleach-heavy products, and harsh chemical cleaners because they may affect the polished surface, sealing layer, or natural onyx appearance.
Cosmetics, toothpaste, soap residue, perfumes, oils, colored liquids, and standing water should be wiped promptly. For backlit installations, LED access, wiring route, waterproof protection, heat management, frame support, and future maintenance access should be planned before site installation.
